APPENDIX D: Updating the Summit’s Firmware
The upload typically takes about two minutes. Once the USM successfully
finishes receiving the new firmware, it should beep and reset itself
automatically. (If the automatic reset doesn’t occur, you can manually reset
the USM by cycling power to it—no data loss will occur. If you do so, check
the firmware version that the USM reports when you click on “Check Device
Information” again. [The USM will also report this in the OSUI’s Information
Menu—see Section 5.5.] If the USM is still reporting the version it was
running previously, the upload wasn’t successful and you’ll have to start it
again.)
9. When the upload is finished, click on “Disable Port” and exit the Update
Utility. (Do this even if you’re planning on upgrading more USMs later.)
10. Disconnect the serial cable from the USM’s administration port.
11. Repeat steps 1 through 10 for each USM whose firmware you want to
upgrade.
To proceed to use the downloaded files and Update Utility to upgrade the
firmware of your Base Unit(s), take these steps unless the current release notes
specify otherwise:
12. Run the DB9 cable you’ve been using to upgrade the USMs between the PC
and the DB9 female administration port of an active Base Unit. You don’t
have to disconnect the Base Unit from any attached devices or existing
cascade; cascaded Base Units don’t have to be upgraded in any particular
order.
13. At the PC with the Update Utility installed on it, launch the Utility by double-
clicking on its icon.
14. Select the correct serial port and click on the “Activate Port” button to initiate
communication with the Base Unit.
15. Click on “Load Hex File” and select the Base Unit firmware contained in the
firmware-distribution file; these will be named “S03A--xxxx,” where xxxx 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.”
16. Click on “Test Hex File.”
17. Click on “Check Device Information.”
