MAINT (PN’s Maintenance Circuit Pack)
Issue 1 June 2005 1499
2000 ABRT Response to the test request was not received within the allowable time
period.
1. Retry the command at 1-minute intervals up to 5 times.
2033 ABRT Internal system error.
1. Retry the command at 1-minute intervals up to 5 times.
2034 ABRT Background maintenance on the PN’s Maintenance circuit pack is
running the Serial Channel Local Loop-around test.
1. Wait 30 seconds, and retry the test up to 5 times.
22901 ABRT Test disabled via software patch.
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.
