Processor and Maintenance Circuit Pack LEDs

Processor and Maintenance Circuit
Pack LEDs
The front panels of the Processor circuit pack and the Maintenance circuit pack
are identical. Each has two groups of LEDs. One group indicates the status of the
pack, and the other group (which includes Major, Minor, and Warning alarms)
reflects maintenance conditions in the entire system, including the PPN and EPN
cabinets. See

system, the yellow LED is always off for the Standby Processor and
Memory circuit packs even when in Maint mode.

the system has detected a fault in this circuit pack.
NOTE:
Alarms on the PROCR, PR-MAINT, MEMORY, and PR-MEM MOs
are indicated by the red LED on the Processor circuit pack.
—
the system is running tests on this circuit pack.
NOTE:
On the Standby Processor circuit pack, green means that the
Standby Switch Processing Element (SPE) is not refreshed (that is, it
is in Maintenance or Down Mode).
NOTE:
On the Maintenance circuit pack, the green LED may blink very
faintly once per second. This is the normal operating state of the
Maintenance circuit pack. The faint blink is due to a once-per-second
self-test executed by the Maintenance circuit pack.
