LED Indicators for Power Status
The LEDs that indicate the status of the backplane voltage signals are explained in
the table below.
When an LED fails to activate, this indicates a problem with one of the voltage sig-
nals. Check that the power supply connector is correctly attached to the backplane. If
the problem persists, consult an experienced technician.
