Diagnosing Power Problems with the LEDs

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

Stack Link LED is

Flashing Green/Amber

•

The uplink/downlink has failed.

•

For the indicated stack link, check that the stacking
cables are properly connected. Replace the stacking
cable if necessary.

•

Power cycle the switch to try and clear the condition.

Link 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.

•

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.

Table A-2 Power/RPU LEDs
