To Check System Power And Status; Checking System Power And Status - Nortel BCM200 Installation And Maintenance Manual

Checking system power and status

After you connect power to the BCM system, the Power LED on the front of the base function tray
and expansion unit lights. Once the system services have reactivated, the Power and Status LEDs
turn solid green. For further information on LED indicators, see
on page 77.
LEDs in position 3 to 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.

To check system power and status

1 If the base function tray Power LED does not light:
a Disconnect the power cords.
b Check all cables and power connections.
c Ensure that the AC outlet has power.
d Reconnect the power cords.
If the Power LED still does not light, then you have a faulty power supply module. For details
