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:
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 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
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 Board Control
Processor (BCP) is inactive.
MMI Connectors
S 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.
S 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.
