Chapter 5 Business Communications Manager System Startup 129
Installation and Maintenance Guide
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.
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.
LEDs in position 3-8 will flash when the SSM is not communicating (during startup,
shutdown or operating system hang).
Table 16 describes the possible operating states of the LEDs on the front of the Business
Communications Manager base function tray. The Business Communications Manager expansion
unit has both a power and a status LED, which provide the same indicators as for the base function
tray.
Note: During system initialization, the system performs diagnostics on the hardware
configuration size and installation. If the power fails, system data remains in memory.
