2. Wait 15 minutes.
3. If the error recurs, replace the Maintenance/Test circuit pack.
When this alarm is active, the yellow LED is in one of three states:
■
If there is no activity on the Maintenance/Test circuit pack, the yellow
LED is off. It is OK to replace the Maintenance/Test circuit pack.
■
If there is an indication of an uncorrectable fault on the Packet Bus,
the yellow 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 (that is,
ISDN Test Call), or if there is an indication of a correctable fault on
the Packet Bus, the yellow 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 is
able to 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.
