Using Technician Interface Software
8-42 117381-A Rev. A
If you need more contiguous free space for the image:
• Delete unnecessary or obsolete files.
• Compact the contents of the flash card.
2. Transfer the PROM image files (for example, freboot.exe and frediag.exe)
to the flash card.
From the Technician Interface, use the
tftp command. (See “In-Band File
Transfers” in Chapter 4 if you need more information.)
3. Establish a Technician Interface session with the router.
See Chapter 1 if you need more information about how to open a Technician
Interface session with the router.
4. To update a boot PROM, enter
prom -w
<volume_no.>
:
<Boot_PROM_source_file>
<slot_ID >
For example:
prom -w 2:freboot.exe 3
5. To update a diagnostics PROM, enter
prom -w
<volume_no.> <Diag_PROM_source_file>
<slot_ID >
For example, to upgrade the diagnostics PROMs in slots 2 through 5, enter
prom -w 2:frediag.exe 2-5
More examples of command lines appear at the end of this section.
Note: Once you enter the prom command, it must run to completion. The
control-c (abort) command is disabled for the duration of the
prom command
execution to allow it to run to completion. Upgrading takes from 2 to 10
minutes per PROM. Verifying takes up to 2 minutes per PROM.
Caution: When upgrading PROMs with new software, upgrade all slots that
contain FRE modules to avoid a mismatch of software.
