Symptom

Action

Power LED is Off

•

Internal or redundant power supply has failed or is
disconnected.

•

Check connections between the switch, the power cord,
the wall outlet.

•

Contact SMC Tech Support.

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.

1000BASE-T port is

not functional

•

Verify that the RJ-45 cable is plugged properly on the
front panel M2 port.

•

Check the M2 module is unplugged on the rear panel.
