Halting Packet Transfer Between Slots

When you reset a slot containing a processor (FRE) module, the router

automatically halts packet transfer between the resetting slot and the other slots in

the router. Packet transfer automatically resumes after the slot is operational again.

When you hot-swap a FRE module, the router also automatically halts and then

resumes packet transfer.

Verifying and Upgrading Software

The Technician Interface provides the following commands for verifying and

upgrading executable software:

•The

readexe

command calculates file header and image checksums on

executable files on the file system, verifies that the checksums match those

within the files, and displays the results and all file header information. Use

this command to validate executable files before upgrading.

•The

prom -w

command erases the PROM and copies the contents of the

PROM update file to the PROM. Use this command to update (write) a PROM

with new software.

•The

prom -v

command compares the contents of a PROM file on the file

system to the contents of a PROM. Use this command to verify that the

software installed in the file system matches the software loaded on a PROM.

The executable software consists of the following binary files:

• The diagnostics image file is named frediag.exe. To upgrade with a new

diagnostics image, transfer the new frediag.exe file to the file system, issue the

readexe

command to validate it, and issue the

prom -w

command to load

(write) it onto the diagnostics PROM. The diagnostics PROM device supplies

the FRE processor module with diagnostic instructions during a cold start.

If you want to verify that the image resident on the diagnostics PROM

matches the frediag.exe file, use the

prom -v

command.

• The bootstrap image file is named freboot.exe. To upgrade with a new

bootstrap image, transfer the new freboot.exe file to the file system, issue the

readexe

command to validate it, and issue the

prom -w

command to load

(write) it onto the bootstrap PROM. The bootstrap PROM supplies the FRE

module with bootstrap instructions during a cold start.
