PA Module LED
Each PA 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 — PA module is active and is reporting no alarms (Normal
condition).
S Flashing GREEN/RED — PA 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.

connectors as they are concealed by the removable lens.
The LED indicators and their states are as follows:
PWR/ALM LED
S RED – fault on module

S Off – module is inactive, off-line, or not processing traffic.
S Slowly Flashing GREEN – OOS_ROM no alarm.
S Rapidly Flashing Green – OOS_RAM no alarm.
S Solid GREEN – module is INS_ACT, on-line, processing traffic.
PWR/ALM and ACTIVE LEDs
S Solid RED – module is powered but is in reset or the BCP is inactive.

primarily in the development or factory environment but may be used
in the field for debugging purposes.
S The RJ–11 ethernet port connector (eight-pin) is intended to be used
primarily in the development environment but may be used in the field
for high data rate debugging purposes.
