ReferenceTo configure an NMC to be a member of a Synchronized Control Group, refer to the "Sync Control Page" section in this chapter.
- To initiate a control action for the UPS of this NMC only, select "No" for "Apply to Sync Control Group?"
- To initiate a control action for all members of a Synchronized Control Group to which this NMC belongs (if the option is allowed), select "Yes" for "Apply to Sync Control Group?".
Note: The option to apply an action to a Synchronized Control Group is displayed only if the UPS supports Synchronized Control Groups and if the NMC is an active (enabled) group member.
Synchronized Control Group Guidelines
- All UPSs in a Synchronized Control Group must be the same model.
- In a Synchronized Control Group of 3-phase UPSs, the shutdown mode (set at the UPS) must be either Normal or Secure for each UPS.
The Synchronization Process
If you apply an action to a Synchronized Control Group, enabled members of the group behave as follows:
- Each UPS receives the command regardless of output status.
- The action uses the delay periods (such as Shutdown Delay, Sleep Time, and Return Delay) configured for the initiating UPS.
- When the action begins, a UPS that is unable to participate retains the present output status while the other UPSs perform the action. If a UPS is already in an output state that the action requires (a UPS is already off when the Reboot UPS action starts), that UPS logs an event, but performs the rest of the action, if any.
- All participating UPSs synchronize the performance of the action (within a one-second time period under ideal conditions, but sometimes longer.
- In reboot and sleep actions:
- Immediately before the initiating UPS begins waiting the time specified as Return Delay. By default the UPS waits up to 120 seconds for any UPS that does not have input power to regain that power. Any UPS that fails to regain input power during that delay does not participate in the synchronized restart. The UPS waits until the input power returns before restarting.
- The LEDs on the front of the UPS are not sequenced the same as a normal (not synchronized) reboot or sleep action.
- UPS status and events are reported in the same way for synchronized actions as for actions on individual UPSs.
Actions (for a single UPS and Synchronized Control Groups)
- All actions except "Put UPS In Bypass" and "Take UPS Off Bypass" are supported for individual UPSs
- Put UPS in Bypass and Take UPS Off Bypass are supported only for individual UPSs, not for Synchronized Control Groups
ReferenceFor more information about the delays and settings in the following table, refer to the "Configuration Pages" section and the "Sync Control Page" section in this chapter. To apply" UPS Alarm Test to a Synchronized Control Group", refer to the "Diagnostics Page" section in this chapter.
| Action | Definition |
|---|---|
| Turn UPS On ("Web Interface") "ups -c On" ("Command Line Interface") |
Turns on power at the UPS. For a UPS model with outlet groups, this action then turns on the outlet groups according to the value for "Power On Delay" for each group. Refer to the "The Settings Option (including automatic load-shedding)" section in this chapter. For a Synchronized Control Group, after a delay of a few seconds, the action turns on all enabled group members that have input power. |
| Turn UPS Off ("Web Interface") "ups -c Off" ("Command Line Interface") |
Turns off the output power of the UPS and (for a UPS model with outlet groups) of all the outlet groups immediately, without a shutdown delay. The UPS and all the outlet groups remain off until you turn on the power again. For a Synchronized Control Group, this action turns off power at all enabled members of the group. No "Shutdown Delay" value is used. The UPSs turn off after a few seconds and remain off until you turn on the power. refer to the "The Shutdown Option" section in this chapter. For a synchronized turn-off action that uses the value of the "Shutdown Delay" of the initiating UPS, use SNMP. For the "upsAdvControlUpsOff OID", set the value to "turnUpsSyncGroupOffAfterDelay". |
| "ups -c GraceOff" ("Command Line Interface") | Turns off outlet power of the UPS and (for a UPS model with outlet groups) all the outlet groups after the "Maximum Required Delay" and the configured "Shutdown Delay". |
| Reboot UPS ("Web Interface") "ups -c Reboot" ("Command Line Interface") |
Restarts the attached equipment by doing the following: Turns off power at the UPS after "Shutdown Delay". Turns on power at the UPS after the UPS battery capacity returns to at least the percentage configured for "Minimum Battery Capacity" or can support the load for the time configured for "Return Runtime Duration". (The parameter differs by UPS model.) The UPS then waits the time specified as "Return Delay". Refer to the "The Shutdown Option" section in this chapter. For a UPS with outlet groups, "Power On Delay" occurs after the UPS turns on and before an outlet group turns on. On the UPS tab, configure "Power On Delay" for each outlet group by using the settings option under "Outlet Groups". Refer to the "The Settings Option (including automatic load-shedding)" section in this chapter. For a Synchronized Control Group action: 1. This option turns off power at the UPSs that are enabled group members after waiting the time configured as "Shutdown Delay" for the initiating UPSs. Refer to the "The Shutdown Option" section in this chapter. 2. The initiating UPS waits up to the number of seconds specified as "Power Synchronized Delay" to allow time for group members to regain input power. If all group members already regained input power, this delay is omitted. If all group members regain input power during the delay, the rest of the delay is canceled. To configure "Power Synchronized Delay", refer to the "Configure a Synchronized Control Group Member" section in this chapter. 3. "Return Delay" starts when the initiating UPS is at the configured "Minimum Battery Capacity" (or "Return Runtime Duration"). Refer to the "The Shutdown Option" section in this chapter. "Minimum Battery Capacity" (or "Return Runtime Duration") of the initiating UPS is also required of group members. However, you can reduce a group members requirement by configuring that members "Minimum Battery Capacity Offset" (or "Return Runtime Duration Offset"), if the initiators "Minimum Battery Capacity" is 50 percent, and the members "Minimum Battery Capacity Offset" is 5 percent, that member needs battery capacity of 45 percent to reboot. Refer to the "Configure a Synchronized Control Group Member" section in this chapter. |
| "ups -c GraceReboot" ("Command Line Interface") | This action is similar to "Reboot UPS", but with an additional delay before the shutdown. Attached equipment shuts down only after the UPS (or the initiating UPS, for a Synchronized Control Group action) waits the "Maximum Required Delay". For a UPS with outlet groups, "Power On Delay" occurs after the UPS turns on and before an outlet group turns on. On the UPS tab, you configure "Power On Delay" for each outlet group through the settings option under "Outlet Groups". Refer to the "The Settings Option (including automatic load-shedding)" section in this chapter. |
| Put UPS To Sleep ("Web Interface") "ups -c Sleep" ("Command Line Interface") |
Puts the UPS into sleep mode by turning off the output power for a defined period: The UPS turns off output power after waiting the time configured as "Shutdown Delay". Refer to the "The Shutdown Option" section in this chapter. For a synchronized control group action, the NMC of the initiating UPS waits up to the number of seconds configured as "Power Synchronized Delay" for enabled group members to regain input power before the UPS starts the "Return Delay". If all group members already regained input power, the "Power Synchronized Delay" is omitted. If all group members regain input power during the delay, the rest of the delay is canceled. Refer to the "Configure a Synchronized Control Group Member" section in this chapter. |
| "ups -c GraceSleep" ("Command Line Interface") | Puts the UPS into sleep mode (turns off power for a defined period): The UPS turns off output power after waiting the "Maximum Required Delay" and the "Shutdown Delay". Refer to the "Maximum Required Delay" section and "The shutdown option" section in this chapter. When input power returns, the UPS turns on output power after two configured periods of time: the "Sleep Time" and "Return Delay Time". Refer to "The shutdown option" section in this chapter. For a synchronized control group action, the Management Card of the UPS initiating the action waits up to the number of seconds configured as the "Power Synchronized Delay" for enabled group members to regain input power before the UPS starts the "Return Delay". If all group members have already regained input power, the "Power Synchronized Delay" is omitted. If all group members regain input power during the delay, the remainder of the delay is canceled. Refer to the "Configure a Synchronized Control Group member" section of this chapter. |
| Put UPS In Bypass and Take UPS Off Bypass ("Web Interface") "ups -b Enter ups -b Exit" ("Command Line Interface") |
Controls the use of bypass mode. |
Configuration Pages
The Configuration Pages are not available on all UPSs
The Power Option
ReferenceThe available settings differ based on the UPS model. For detailed information about fields and values available through the power option and specific to your UPS model, see the online help or contact your Caterpillar dealer.
You can configure the following types of model-specific items:
- Voltage settings that determine the voltage at which the UPS begins to use automatic voltage regulation or switches to battery operation and that determine how sensitive the UPS is to voltage variation.
- Bypass settings define conditions under which the UPS can switch to bypass mode.
- Alarm thresholds based on available runtime and redundant power and on UPS load.
The Shutdown Option
| Setting | Definition |
|---|---|
| Low Battery Duration | How long the UPS can run on battery power after a low-battery condition occurs. |
| Maximum Required Delay | Reports the delay defined by the "Maximum Required Delay" setting. |
| Shutdown Delay | How long the UPS waits before the UPS shuts down in response to a turn-off command. |
| Basic Signaling Shutdown | When enabled, provides safe system shutdown and notification, but without the advanced features available with advanced signaling. Enable basic-signaling shutdown if your computer is connected to the UPS by a basic-signaling cable, and the type of UPS either does not support advanced signaling or is configured to communicate in basic signaling. |
| Basic Low Battery Duration | Available only for some UPS models. Defines the amount of available battery runtime at which the UPS sends the signal for a low-battery shutdown if basic-signaling shutdown is enabled. |
| Sleep Time | How long the UPS sleeps (keeps the outlet power turned off) when you use the "Control" option "Put UPS To Sleep". |
| Return Runtime Duration | Most UPSs support one of the following settings to ensure that the UPS batteries have time to charge. Then, if input power fails soon after the UPS restarts, the UPS can perform a graceful shutdown. (The UPS must also wait the time defined as "Return Delay" before the UPS turns on.) "Return Runtime Duration": How long the UPS must be able to support the load by battery power in order for the UPS to end the sleep time (or turn back on when rebooted) and resume providing output power "Minimum Battery Capacity": The minimum battery capacity, as a percentage of full capacity, required in order for the UPS to end the sleep time (or turn back on when rebooted) and resume providing output power. |
| Minimum Battery Capacity | |
| Return Delay | How long the UPS waits before the UPS turns on after a shutdown that was caused by a power failure or after a scheduled shutdown. NOTE: The UPS must also have the capacity specified by the "Minimum Battery Capacity" setting or the available runtime specified as "Return Runtime Duration" before the UPS can turn on. |
The General Option
Settings vary by UPS model. Each UPS model supports only some of the following:
| Setting | Definition |
|---|---|
| UPS Name | A name to identify the UPS. Maximum length: eight characters. |
| UPS Position | The physical orientation of the UPS, rack, or tower. |
| Audible Alarm | Enable or disable the audible alarm of the UPS, and, for some UPS models, define the condition that will cause the alarm to sound. |
| Last Battery Replacement | The month and year of the most recent battery replacement. |
| Number of Batteries or External Batteries |
The number of batteries, excluding built-in batteries, that the UPS has. Some models that have more than 16 batteries must add batteries in quantities of 16 (16, 32, 48), but can then be adjusted to the correct value. |
| External Battery Cabinet | The battery cabinet Amp-Hour rating of an external battery source. |
The Reset UPS Defaults Option
Mark this checkbox to reset all UPS configuration settings to the default values, except "UPS Name" and "Output Voltage". The time required to reset configuration settings may be a minute or more.
The Self-test Schedule Option
Use this option to define when the UPS will initiate a self-test.
Diagnostics Page
You can run a self-test or a run-time calibration for any UPS. The UPS audible alarm test is model-specific and may not be available for your UPS.
Note: The Diagnostics Page is not available on all UPSs
| Field | Description |
|---|---|
| Self-test | The result (passed, failed, or unavailable) and date of the last UPS self-test. |
| Calibration | The result of the last runtime calibration. A calibration recalculates remaining runtime and requires the following: Because a calibration temporarily depletes the UPS batteries, you can perform a calibration only if battery capacity is at 100 percent. For some UPSs, the load must be at least 7 percent for a calibration to be performed. |
| Initiate | Select a diagnostic procedure to perform immediately: a test of the UPS audible alarm, a UPS self-test, or a run-time calibration. When you test the audible alarm of a member of a Synchronized Control Group: In the "Web Interface", this option tests the alarms of all enabled members of the group. In SNMP, you can set the OID "upsAdvControlFlashAndBeep" to "flashAndBeep" to test the alarm of an individual UPS or to "flashAndBeepSyncGroup" to test the alarms of all enabled group members. |
Outlet Groups
ReferenceOutlet grouping is available on some UPS models only. To determine whether your UPS model supports outlet groups, see your UPS documentation.
The available settings differ based on the UPS model. For detailed information about fields and values specific to your UPS model, see the online help or contact your Caterpillar dealer.
Main Outlet Groups
Some UPS models provide AC power to one main outlet group.
Note: The main outlet group controls the distribution of power to all switched outlet groups for the UPS.
- If the main outlet group is off, the switched outlet groups cannot be turned on.
- If you turn off the main outlet group, the UPS turns off the switched outlet groups first, then turns off the main outlet group.
- To turn on a switched outlet group, the UPS must turn on the main outlet group first, and then turn on the switched outlet group.
Switched Outlet Groups
Some UPS models provide power to switched outlet groups. Each group can perform actions independently of the other groups. By controlling each outlet group remotely, you can start or stop devices sequentially and restart locked devices.
How outlet groups turn on and off depend on how the groups are configured and how you turn the UPS on or off:
- Until you configure the actions described in "The Control Option" section of this chapter and the related delays described in "The Settings Option (including automatic load-shedding)" section of this chapter, when you turn on the UPS output, any outlet group that is off turns on by default and applies power to all devices attached to the outlets in that group.
- After you configure the actions and delays, the actions and delays control how outlet groups turn on and off when you turn the UPS on or off from the user interface of the Network Management Card or the display interface at the UPS.
The Control Option
While the output of the UPS is on, select the "UPS" tab and then the "Control" option under "Outlets" or "Outlet Groups" to turn on, turn off, or restart any outlet group. This option lists by name and state (on or off) each outlet group that is configured through the "Settings" option.
You can select any of the following actions (or no action) for the group.
- When the state of the outlet group is "off":
On Immediately - Turn on the group immediately.
On with Delay - Turn on the group after the number of seconds configured as "Power On Delay".
- When the state of the outlet group is "on":
Off Immediately - Turn off the group immediately.
Off with Delay - Turn off the group after the number of seconds configured as "Power Off Delay".
Reboot Immediately - Turn off the group immediately, then turn on the UPS after the number of seconds configured as "Reboot Duration" and "Power On Delay".
Reboot with Delay - Turn off the outlet group after the number of seconds configured as "Power Off Delay", then turn on the UPS after the number of seconds configured as "Reboot Duration" and "Power On Delay".
- For some UPS models, when the state of the outlet group is "on" and the UPS is on battery:
Shut down Immediately, AC Restart - Turn off the group immediately. After the number of seconds configured as "Reboot Duration" and "Power On Delay", check that AC utility power has returned and the UPS can support the minimum return runtime demand, then turn on the group.
Shut down with Delay, AC Restart - Turn off the group after the number of seconds configured as "Power Off Delay". After the number of seconds configured as "Reboot Duration" and "Power On Delay", check that AC utility power has returned and the UPS can support the minimum return runtime demand, then turn on the group.
After you select an action, click "Next>>" to view a detailed description of the action, including the duration of any delays. Click "Apply" to confirm the action.
The Settings Option (including automatic load-shedding)
Click the name of an outlet group to view or configure the groups settings.
Outlet Group Name and Status
Define the outlet group name or view the state of the outlet.
| Setting or Field | Description |
|---|---|
| Name | A name for the outlet group displayed with the outlet group number wherever the interface displays that outlet group number. |
| State | Displays the state of the outlet group (on or off). |
Sequencing Settings
Settings vary by UPS model. Use the sequencing options to define how the UPS will respond to user-issued commands.
| Setting or Field | Description |
|---|---|
| Power On Delay | When this outlet group is off, the UPS waits this delay (up to 600 seconds) before turning on when "Delayed On", "Reboot", or "Delayed Reboot" is selected as the action. To override "Power On Delay", mark the "Never" checkbox. Only the "Immediate On" action will turn on outlets when "Never" is marked. |
| Power Off Delay | When this outlet group is on, the UPS waits this delay (up to 600 seconds) before turning off when "Delayed Off", "Reboot", or "Delayed Reboot" is selected as the action. (During a delayed reboot, the outlet group then waits the number of seconds configured as "Reboot Duration" and "Power On Delay" before the UPS turns on.) To override "Power Off Delay", mark the "Never" checkbox. Only the "Immediate Off" action will turn off outlets when "Never" is marked. |
| Reboot Duration | When this outlet group is on: If "Reboot" is selected as the action, the outlet group turns off immediately and then waits this delay (up to 600 seconds) before turning on. If "Delayed Reboot" is selected as the action, the outlet group waits these three delays: "Power Off Delay" before turning off, and "Reboot Duration" followed by "Power On Delay" before turning on. |
| Min Return Runtime | The minimum amount of time the UPS must be able to support the load before the UPS can turn on again. |
Load-shedding Options
Settings vary by UPS model. Use the load-shedding options to define how the UPS will respond to alarms. The UPS provides automatic, sequenced, load-shedding when a problem occurs with input voltage or battery capacity and provides automatic sequenced start-up of outlet groups when the problem is resolved.
| Setting | Description |
|---|---|
| Settings that turn off this outlet group | A power failure is longer than the number of seconds you specify. The remaining UPS runtime is less than the number of seconds you specify. The UPS is overloaded (the power demand of the devices connected to the UPS exceeds the amount of power the UPS can provide). Input power fails and the UPS battery capacity drops below the percentage you specify. Output drawn from the UPS exceeds the percentage of UPS output load you specify. Skip outlet off delays. (Turn the outlet group off immediately, without waiting the number of seconds configured as "Power Off Delay". By default, this option is disabled.) Stay off after power returns. (Remain off when AC utility power returns. By default, this option is disabled, and the UPS waits the number of seconds configured as "Power On Delay", then turns on the outlet groups.) |
| Settings that turn on this outlet group | The outlet group has waited the number of seconds you specify. The battery recharges to the percentage of full capacity you specify. |
Outlet Group Events and Traps
A change in the state of an outlet group generates the event" UPS: Outlet Group turned on" with a severity of Informational, or "UPS: Outlet Group turned off" with a severity of Warning. The format of event messages is "UPS: Outlet Group group_number, group_name, action due to reason". For example:
- UPS: Outlet Group 1, "Web Server", turned on due to user control.
- UPS: Outlet Group 3, Printer, turned off due to line fail.
By default, the event generates an event log entry, e-mail, and a Syslog message.
If you configure trap receivers for the events, trap 298 is generated when an outlet group turns on, and trap 299 is generated when an outlet group turns off. The event message is the trap argument. The default severity level is the same as for the event.
Scheduling Page (for Shutdowns)
Note: The Scheduling Page is not available on all UPSs
Select the type of shutdown to schedule, One-time Shutdown, Daily Shutdown, or Weekly Shutdown (at one, two, four, or eight week intervals), and then use these options:
Name - Define a name for the shutdown.
Shut down daily at, Shutdown, or Shutdown on - Define when the shutdown will begin, and for a weekly shutdown, the number of weeks between shutdowns.
Turn back on - Define whether the UPS will turn on at a specific day and time, "Never" (the UPS must be turned on manually), or "Immediately" (the UPS will turn on after waiting 6 minutes and the time specified as the Return Delay).
ReferenceTo configure the Return Delay, refer to the "Return Delay" section in this chapter.
Schedule a Synchronized Shutdown
All scheduled shutdowns will be synchronized when the UPS whose NMC initiates the shutdown is a member of a Synchronized Control Group and the UPSs status as a member is enabled. Always schedule all shutdowns through the same member of the group. For a scheduled synchronized UPS shutdown to occur, a network connection to each UPS in the group must exist at the time at which the action is scheduled to occur.
| NOTICE |
|---|
Do not schedule shutdowns through more than one group member. Such scheduling may cause unpredictable results. |
Edit, Enable, Disable, or Delete a Scheduled Shutdown
To access and edit the parameters of a scheduled shutdown, disable the shutdown temporarily, or delete the shutdown permanently, click the shutdown name in the list of shutdowns, and follow the on-screen instructions.
Sync Control Page
Note: The Sync Control Page is not available on all UPSs
Guidelines for Synchronized Control Groups
Before you configure this UPS as a Synchronized Control Group member, review these guidelines:
- All UPSs in a Synchronized Control Group must be the same model.
- In a Synchronized Control Group of 3-phase UPSs, the shutdown mode setting configured at the UPS must be the same (either "Normal" or "Secure") for all group members.
- When a members membership in a Synchronized Control Group is enabled, the NMC blocks UPS communications from a connected management device on the serial communications port. However, the NMC still allows access to the "Command Line Interface" on the serial communications port.
Display Status of a Synchronized Control Group Member
The following information is displayed about the Synchronized Control Group membership of this group member when the members group membership is enabled.
| Status item | Description |
|---|---|
| IP Address | The IP address of the Network Management Card of this group member (UPS). |
| Input Status | The state of the input power of this group member: "good" (acceptable) or "bad" (not acceptable). |
| Output Status | The status of the output power of this group member: "On" or "Off" |
Configure a Synchronized Control Group Member
| Parameter | Description |
|---|---|
| Group Membership | Determines whether this Synchronized Control Group member is an active member of the members group. If you disable group membership, this UPS functions as if the group were not a member of any Synchronized Control Group. When you enable or disable Group Membership, the change causes the management interface to reboot the next time you log out. The change takes effect at that time. |
| Control Group Number | The unique identifier of the Synchronized Control Group of which this NMC UPS is a member. This value must be a number from 1 through 65534. A UPS can be a member of only one Synchronized Control Group. All members of a Synchronized Control Group must have the same Control Group Number and Multicast IP Address. |
| Multicast IP Address | The IP address used to communicate among members of a Synchronized Control Group. For IPv6, any valid IPv6 multicast address can be used. For IPv4, the allowed range is 224.0.0.3 to 224.0.0.254. All members of a Synchronized Control Group must have the same Control Group Number and Multicast IP Address. |
| Power Synchronized Delay | The maximum time (120 seconds by default) that the initiating UPS waits, if necessary, for other group members to regain input power when the initiating UPS is ready to turn on. When this delay expires, the initiating UPS waits to recharge the battery to the runtime specified as Return Runtime Duration or the battery capacity specified as Minimum Battery Capacity, if necessary, then waits the time specified as Return Delay, and then turns on. NOTE: For information about configuring the Return Runtime Duration, refer to the "Return Runtime Duration" section in this chapter. For information about configuring the Minimum Battery Capacity, refer to the "Minimum Battery Capacity" section in this chapter. |
| Minimum Battery Capacity Offset or Return Runtime Duration Offset |
A UPS supports only one of these parameters, depending on UPS model. You can configure this value differently for each member of the Synchronized Control Group through the management interface of that member. Minimum Battery Capacity Offset: A percentage of battery capacity that is subtracted from Minimum Battery Capacity of the UPS that initiates a synchronized action to determine the battery capacity required for this group member to turn on during synchronized actions. For information about configuring the Minimum Battery Capacity, refer to the "Minimum Battery Capacity" section in this chapter. Return Runtime Duration Offset: A number of seconds that is subtracted from the Return Runtime Duration of the UPS that initiates a synchronized action to determine the available runtime required for this group member to turn on during synchronized actions. For information about configuring the Return Runtime Duration, refer to the "Return Runtime Duration" section in this chapter. |
| Authentication Phrase | The case-sensitive phrase (15 to 32 ASCII characters) used to authenticate members of a Synchronized Control Group. All members of a Synchronized Control Group must have the same authentication phrase. The default is "APC SCG auth phrase". |
| Encryption Phrase | The encryption key for the protocol that ensures secure communication among members of a Synchronized Control Group. All members of a Synchronized Control Group must have the same encryption phrase. The default is "APC SCG crypt phrase". |
| Synchronized Control Port | The network port that Synchronized Control Groups use to communicate. Use any nonstandard port from 5000 to 32768. |
