DC Power Status LEDs
d.
If the DC Indicator LEDs are not on, suspect the main power supply module or
front panel switch. The power supply (0950-4729) terminal connections
should also be verified with a DVM. Verify the voltages on the power supply
label.
e.
If rear panel fan is not operating and the DC Indicator LEDs are
on,
replace fan.
