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 Avaya
MultiVantage™ software 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

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.
