LPA Shelf LED Status Combinations
LPA Module LED
Each LPA module contains a bi–color LED just above the MMI
connector on the front panel of the module. Interpret this LED as
follows:
S GREEN — LPA module is active and is reporting no alarms (Normal
condition).
S Flashing GREEN/RED — LPA module is active but is reporting an
low input power condition. If no BBX is keyed, this is normal and
does not constitute a failure.
