Using Technician Interface Software

The executable software consists of the following binary files:
• frediag.exe is the diagnostics image file. 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.
• freboot.exe is the bootstrap image file. 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.
If you want to verify that the image resident on the bootstrap PROM matches
the freboot.exe file, use the
prom -v command.
• bn.exe
is the router software image for the BLN, BLN-2, and BCN. an.exe is
the router software image for the AN and ANH. afn.exe is the router software
image for the AFN. asn.exe is the router software image for the ASN. ace.out
is the router software image for the FN, LN, CN, and ALN. When the system
boots, it automatically loads the default router software image (unless you
specify another router software image) from another slot into memory on the
processor module or, if another slot is unavailable, from the file system to
memory. To upgrade with a new image, transfer it to the file system and reset
the system; do not use the
prom -w command when upgrading with a new
router software image.
The sections that follow describe how to use the readexe, prom -w, and prom -v
commands to validate, upgrade, and verify executable software.
Note: You cannot edit executable files.
