If there are no Packet Bus alarms, reset the circuit pack with the
busyout
board PCSS
and
reset board PCSS
commands. If the Circuit Pack
Restart Test (#594) passes, then the on-board circuitry is healthy. Retire
the alarm with the
test board PCSS long clear
command. If the Circuit
Pack Restart Test (#594) fails, replace the circuit pack.
k. The SPE software detects an excessive number of up-link messages from
the TN2185 board within a certain time period. To prevent the faulty board
from flooding the switch with data, the switch software takes the board out
of service and alarms it. The switch software also tells the Archangel to
ignore up-link messages from the board.
When the board is alarmed due to this error, the switch software
periodically puts the board back in service and tells the Archangel to
process up-link messages from the board. If the problem still exists, the
software takes the circuit pack out of service again. If the circuit pack
does not exhibit the problem for a certain time period, then maintenance
software resolves the alarm and the circuit pack is left in service.
l. The circuit pack received an inconsistent down-link message (a bad
header, bad port number, bad data, bad subqualifier, or bad logical link)
over the Control Channel.
m. The board is receiving data from the bus faster than it can distribute the
data to its endpoints, causing the FIFO RAM buffer to overflow. This error
can occur occasionally due to the statistical sizing of the buffers. If it
occurs frequently, it may indicate a LAPD parameter mismatch. LAPD
should recover from this problem, but it may degrade the performance of
the LAN bus.
When this error is reported, maintenance reads and clears the board
counter and logs the problem in the maintenance error log.
n. Bad translation RAM detected, but the call continues by using another
translation location. The circuit pack reports this error when it cannot
update NPE/NCE memory and read it back. This error is not
service-affecting and can be ignored, but can lead to other types of errors
against this circuit pack.
