Diagnosing Power Problems with the LEDs

The Power and RPU LEDs work in combination to indicate power status as
follows.

Link/Act LED

is Off

• Verify that the switch and attached device are powered

on.

• Be sure the cable is plugged into both the switch and

corresponding device.

• If the switch is installed in a rack, check the connections

to the punch-down block and patch panel.

• Verify that the proper cable type is used and its length

does not exceed specified limits.

• Check the adapter on the attached device and cable

connections for possible defects. Replace the defective
adapter or cable if necessary.
