BBX2 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:
 Solid GREEN – INS_ACT no alarm
 Solid RED Red – initializing or power-up alarm
 Slowly Flashing GREEN – OOS_ROM no alarm
 Long RED/Short GREEN – OOS_ROM alarm
 Rapidly Flashing GREEN – OOS_RAM no alarm
 Short RED/Short GREEN – OOS_RAM alarm
 Long GREEN/Short RED – INS_ACT alarm
MCC24/8E LED Status
Combinations
The MCC24/MCC8E module has LED indicators and connectors as
described below (see Figure 6-3). 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
 RED – fault on module
ACTIVE LED
 Off – module is inactive, off-line, or not processing traffic.
 Slowly Flashing GREEN – OOS_ROM no alarm.
 Rapidly Flashing Green – OOS_RAM no alarm.
 Solid GREEN – module is INS_ACT, on-line, processing traffic.
PWR/ALM and ACTIVE LEDs
 Solid RED – module is powered but is in reset or the BCP is inactive.
MMI Connectors
 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.
 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.
