This chapter provides a quick look-up, to let you quickly isolate
the cause of a problem, and corrective actions required.

3RZHU6XSSO\

Symptom

Probable Cause

Corrective Action

Loss of power to the
power supply

(All rack LEDs are off)

The 16-pin connector on the back of the
power supply is not properly connected
with its mate.

Remove power from the chassis. Re-seat
the power supply.

Power to the rack was cycled too fast,
causing a large current inrush and
resulting in a thermal overload.

Remove power to the rack for a MINIMUM
of two minutes. Then restore power.

Blown fuse on the power supply.

Check the fuse to see if it is blown. Replace
if necessary.

Line power is not connected to the
power supply.

Verify that line power is connected to the
power supply.

Improper voltage jumper setting.

Check the jumper setting to verify it matches
the input voltage.

Defective power supply.

Replace power supply.
