MAINT (PN’s Maintenance Circuit Pack)
Issue 1 May 2002
8-1033555-233-143
FAIL The on-board circuitry associated with the standby serial link is defective.
Since the PN’s Maintenance circuit pack reported this failure, the on-board
circuitry associated with the active serial link is functional.
1. This test checks the circuitry on the PN’s Maintenance circuit pack
associated with the standby Expansion Interface link.
a. In a switch without duplicated Port Network Connectivity (PNC), current
service will not be affected because the circuitry failing is not being
used. Nevertheless, a Minor alarm will remain in the Alarm Log against
MAINT. Therefore, the PN’s Maintenance circuit pack must be
replaced.
b. In a switch with duplicated PNC, service is not affected as long as you
do not interchange the PNCs. Otherwise, the connection to the PN’s
Maintenance circuit pack will be lost. Losing this connection would
mean losing connectivity to the terminal and PN Environment
maintenance. The PN’s Maintenance circuit pack must be replaced to
correct this problem.
PASS The on-board circuitry associated with both Expansion Interface circuit pack
serial links is good. If there is still a problem communicating with the PN’s
Maintenance circuit pack, check the following:
1. The cable comprising the serial link (B carrier Expansion Interface circuit
pack to PN’s Maintenance circuit pack only) may be defective.
2. The PN’s Maintenance circuit pack may actually be defective.
NOTE:
This test may not be 100 percent accurate.
3. The Expansion Interface circuit pack on the standby link may be defective.
