SERVSWITCH™ SUMMIT
Figure D-1. The main window of the Update Utility.
4. Select the correct serial port (COM1, COM2, COM3, or COM4) and click on
the Activate Port button to initiate communication with the USM.
5. Click on “Load Hex File” and select the USM firmware contained in the
firmware-distribution file; these will be named “S10A-xxx,” where xxx is a
hexadecimal representation of the firmware’s version number. The text on
the first button in the “Upgrade Information” pane of the window should
change to “Send to Summit.”
6. Click on “Test Hex File.” The Utility will verify the file’s integrity.
7. Click on “Check Device Information” to confirm that the PC is successfully
communicating with the USM, and that it would in fact be desirable to
replace the USM’s current firmware with the version you’ve downloaded.
8. Click on “Send to Summit” to begin uploading the new firmware to the USM.
Both the PC and the USM need to remain powered on during the transfer,
and you should be careful not to disconnect the cable between them. (If
either device loses power or the cable comes loose, this will not cause the
USM to run with incomplete firmware or any other serious problems, but you
will have to restart the upload process from scratch.)
