Check System power and Status

After you connect power to the Business Communications Manager system, the Power LED on the front of the base function tray and expansion unit lights. Once the system services have reactivated, the Status LED turns solid green. Be patient, this can take upto 15 minutes!

The Power LED can indicate RED if the system is in standby mode whereby power is available, but shutdown by the operating system (when UPS) or Overtemp. If the Power LED is red and there is no power, use a paper-clip to select the reset button. Alternatively power cycle the system to restart.

LEDs in position 3-8 will flash when the SSM is not communicating (during startup, shutdown or operating system hang).

Note: During system initialization, the system performs diagnostics on the hardware configuration size and installation. If the power fails, system data remains in memory.

Funtion tray

The table below describes the possible operating states of the BCM base function tray LEDs. The expansion unit has both a power and a status LED, which provide the same indicators as for the base function tray.
