Firmware Update

Description

Firmware update is mandatory:

• At commissioning

• Machines that are in operation

• The next service call

If an update is needed:

1. Place the system in bypass mode.

2. Perform the update.

3. Make sure that the system is on-line.

This update can be made with no parts.

Required Software Files

The new installation must be purchased.

"UPSView.exe"

"Autoloader.exe"

Required Firmware Files

• "APSBootxxx.mot "

• "apc_xxx.ttf"

• "APSLI_COMPRESS_xxx"

• "APSLI_internal_xxx.mot"

• "pcc_xxx.ttf "

• "zzc_xxx.ttf"

Note: "xxx" represents the version number that will change with the new firmware releases.

Use the Auto loader to update the firmware files in a UPS. The "Auto Loader" is a Windows application. The "Auto Loader" will automate the process for the technician.

The first line in the window is the "command/status" window. The "command/status" windows will inform you of the progress of the application. If an input is required, directions will be listed.

Use the pull-down menu to select the "COM" port of the serial device on your computer.

The "Connect" button will establish communications over the selected COM port.

The "User Name and Password" fields will be accessible after communication has been established. Fill in the fields and click the "Start Button".

The larger window contains detailed information on the process. There are four columns of information.

• Target

• IS Rev

• ShB Rev

• Status

The "Target" column will have an arrow pointing to the item that is currently updating.

The "IS Rev" column displays each of the targets current revision prior to the update.

The "ShB Rev" column displays the information that each of the targets should be.

Illustration 1	g01274002

The "Status" column may contain the following information:

• "NA – not applicable, the UPS did not detect this equipment in the UPS."

• "Force – the UPS will update this file regardless of current revision."

• "Updating – this target is in the process of updating currently."

• "Pending – this target will be programmed when the target progression gets to it."

• "Skipped – this file is already at the required revision."

Procedure

Before starting the procedure, put the UPS into BYPASS MODE. Failure to be in BYPASS prior to beginning will allow the Auto load application to place the UPS into BYPASS for you.

The auto load application will not run with any instances of UPSView connected between the UPS and the computer.

1. Connect a PC to the UPS.

2. For MMS, select "MMU" #1 with the PCI rotary switch. Not required for SMS.

3. Open the application UPSView.

4. Establish a direct connection between UPSView and the UPS.

5. Enter a valid user name. Enter a valid password.

6. On the computer, press "Alt-Z". Record all of the "Operating Parameters" except for the defaults. The results will be used for a comparison later.

7. Click on the menu item "Clear Password".

8. Terminate communications in UPSView. "UPSView Menu: Connection > Disconnect"

9. Close UPSView.

   Make sure that the UPSView window is closed. Only one form of communication is possible over the serial cable.

10. Open the application "Autoload.exe".

11. Select the appropriate COM Port.

12. Click the "Connect" button.

13. Follow the instructions that are on the screen. One example of an instruction is entering a username and password when directed.

    Note: If the process has a problem, a message dialog will pop up in a separate window.

    If needed, attempts can be made to use the Auto load utility in recovery mode. The auto load will happen automatically by opening the file "Autoload.exe" again. After two failures, a manual insertion of the files for the firmware update will need to be completed.

14. If the process is successful, a message dialog will pop up indicating a successful update.

15. For MMS, turn the rotary switch to the next position on the board for the PCI and go to Step 10for each remaining MMU.

16. Open the application UPSView.

17. Establish a direct (serial) connection between UPSView and the UPS.

18. Enter a valid user name and a valid password.

19. On the computer, press "Alt-Z". Record all of the "Operating Parameters" except for the defaults for comparison.

    All firmware in the UPS should now be updated.

Bad Values

After performing an update of the firmware, there is a possibility that new parameters have been created in the UPS. Values have never been assigned to the new parameters. The parameters may contain bad values. When bad values are found, the UPS will notify the operator. The operator will be notified with a Notice. The notice will have a message in yellow text that is indicating the reason for the notification.

When a bad value is identified, the UPS will set that parameter to a default value.

To eliminate the bad values, enter your password. Find the parameter in the "Operating Parameters" menu.

After the "Operating Parameter" is selected, a new window will appear. In the new window, enter the new value. The new values will be the default values. Press the "OK" button. Performing the procedure will prevent bad values from being found for the parameter.

If the parameter cannot be found in the "Operating Parameters" menu, make sure that the user has the appropriate password authorization to make parameter changes. In this event, you can send the default value to all the restricted parameters by selecting the "Command" Menu.

In the "Command" menu, click the line that reads "Load restricted default Params to Flash". Following the procedure will set all of the parameters. Access to the default value is not needed.

Compare Operating Parameters

When the bad values have been cleared, compare the "Alt-Z" list that was created at the beginning of the procedure to the values in the UPS now.

Perform another "Alt-Z" and record the new information. The new "Alt-Z" should contain no new lines of text which cannot be explained. If there are unexplained lines of text, go into the "Operating Parameters" Menu and make the appropriate modifications. In most applications, the default values are typically the correct choices.
