IDU LEDs
Table 2-3 maps IDU LED alarm indications against possible causes and
recommended actions.
For a normal IDU, both LEDs will be green.
At startup, Status LEDs will initially be red, then flashing orange, until the
software can apply the correct states.
LEDs will remain unchanged during a soft reset until the software can apply the
correct states
AUX Status Orange
flashing:
Either:
• Configuration corrupt
• Configuration not supported
• Hardware / software
incompatible
9500 MXC software does not support the
(new) AUX. Install latest 9500 MXC
software.
Red: Either:
• FPGA software failure
• Auxiliary channel clock failure
Repair action is required. The failure may or
may not be causing traffic disruption. Use
CT to see detail at a lower alarm level.
NPC Status Orange
flashing:
TDM clock is locked to NPC Lock set in CT System Controls screen.
Unlock using the same screen.
Red: Either:
• FPGA software load failure
• EEPROM failure
• Clock generator failure
• Redundant power supply failed
or one or more rail voltages
outside limits.
• NPC TDM clock error or failure
Repair action is required. The failure may or
may not be causing traffic disruption. Use
CT to see detail at a lower alarm level.
FAN Red: Fan failure (one or both axial fans) Replace the FAN.
