Reliability System. If the test detects a difference, a minor, off-board alarm is
generated.
When checking the software, the test compares the memory resident software
version and patch identifier. It also checks for the presence of a field update file
and, if found, compares the old and new patch identifiers to make sure the same
patch file id loaded on each processor. If the software or update files are
inconsistent, the "list configuration software" command can be used to display
the status of the patch file.
RECOVERY PROCEDURES
This sections describes the procedures to be followed to recover from failures
encountered during the download and application of the update file. The
instructions apply to both simplex and duplex switches; additional detail is given
when needed.
Error on the Transmission of the Download
If the error displayed on the terminal indicates that the download step in the
process failed, there are several culprits:
1. The transmission line could have been noisy. Retry after making all the
following checks. Failed attempts take up room in the hard patch file and
may require a warm start to clear the file.
2. The user may have downloaded the tape/MIPS version of the patch
instead of the flash version.
3. The vintage of the update file may not match the vintage of software
currently running in the system. Check the customer’s vintage using "list
config software" and patch vintage provided in the documentation.
4. The switch may have had difficulty in writing to the hard patch file. Check
the hardware error log for processor/memory board failures.
5. The hard patch file may be full. Issue a "reset system 1". This should cause
valid files to be applied and invalid ones to be erased.
