BBX LED Status Combinations

PWR/ALM LED

The BBX module has its own alarm (fault) detection circuitry that

controls the state of the PWR/ALM LED.

The following list describes the states of the bi-color LED:

S Solid GREEN – INS_ACT no alarm

S Solid RED Red – initializing or power-up alarm

S Slowly Flashing GREEN – OOS_ROM no alarm

S Long RED/Short GREEN – OOS_ROM alarm

S Rapidly Flashing GREEN – OOS_RAM no alarm

S Short RED/Short GREEN – OOS_RAM alarm

S Long GREEN/Short RED – INS_ACT alarm

MCC LED Status Combinations

The MCC module has LED indicators and connectors as described

below (see Figure 6-4). Note that the figure does not show the

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

ACTIVE LED

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.

MMI Connectors

S The RS–232 MMI port connector (four-pin) is intended to be used

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.
