Maintenance Object Repair Procedure

When this alarm is active, the amber LED will be in one of three states:
■ An unlit amber LED indicates no activity on the Maintenance/Test
circuit pack. You can replace the Maintenance/Test circuit pack.
■ If there is an indication of an uncorrectable fault on the packet bus,
the amber LED will be blinking at a rate of 1 Hz. It is OK to replace
the Maintenance/Test circuit pack. Ignore the packet-bus error
indication, since the Maintenance/Test circuit pack has been
determined to be defective.
■ If there is other activity on the Maintenance/Test circuit pack (i.e.,
ISDN test call), or if there is an indication of a correctable fault on
the packet bus, the amber LED will be on steady. If there is an ISDN
test call in progress, it must be halted via the clear isdn-testcall
grp/member command prior to replacing the circuit pack. Ignore
the packet-bus error indication, since the Maintenance/Test circuit
pack has been determined to be defective.
d. This error indicates a failure of the Packet Bus Port Health Inquiry test.
Either the packet-bus port has reported a self-test failure, or the SPE can
communicate with the Maintenance/Test circuit pack but not with the
Maintenance/Test circuit pack packet-bus port. Refer to the description of
the Packet Bus Port Health Inquiry test, and follow the instructions
indicated for the failure code that matches the Aux Data field.
