BBX LED Status Combinations

PWR/ALM LED

The BBX2 and BBX-1X modules have their own alarm (fault) detection

circuitry that controls the state of the PWR/ALM LED.

The following list describes the states of the bi-color PWR/ALM LED

for both BBX2 and BBX-1X cards:

 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

MCC LED Status Combinations

The MCC24E and MCC-1X modules have bi-color LED indicators and

two connectors as described below. See Figure 6-4. Note that the figure

does not show the connectors because 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 Board Control

Processor (BCP) is inactive.

MMI Connectors

 The RS-232 MMI port connector (four-pin) is intended primarily for

development or factory use but may be used in the field for debugging

purposes.

 The RJ-45 Ethernet port connector (eight-pin) is intended primarily

for development use but may be used in the field for high data rate

debugging purposes.
