52 Updating the Hub Firmware
Procedure 4: Update the Hub Device Agent Code
Caution The hub controller firmware must be updated before the device agent code.
The hub will not operate properly if the firmware is updated in the wrong
sequence. See If Firmware Upgrade Appears to Fail on page79 if the firmware
is updated in the wrong sequence.
1. From the Boot menu, enter 1 to update the device agent code. A prompt appears for you
to begin file transfer; for example:
Ready to download Device Agent code to RAM
Start ASCII file (S-record format) transfer now
<Refer to terminal emulator user manual for instructions>
Press control-C at any time to cancel
2. From the terminal emulator application, select the transfer option to send a text file.
The hub’s firmware files have a .frm suffix. Verify that the terminal emulator application
is displaying all file types.
3. Send the following file you downloaded from the web site. (Firmware filenames change
when updated versions are released. Always check the Hewlett-Packard Software
Depot for the latest firmware version and download instructions.) The default directory
for this file is C:\Temp\HUB_FW.
IFCH3821.FRM
The screen is filled with rows of progress indicator dots as the file is transferred; for
example:
...................................................................
...................................................................
....................................
The transfer process can take 10 to 40 minutes. When the file transfer has been
completed, status messages and a transfer prompt appear; for example:
Done, memory range [$00001000:$0005D666]
Ready to transfer Device Agent code from RAM to FLASH
Note, once started, this step must not be interrupted
Press Enter to start, control-C to cancel
