Problem Possible Solutions
The Power LED is not lit.
The Emergency Power LED is not lit.

the power connection. Plug the power cord into
another known working AC outlet.

optional emergency power supply and have the
primary power supply serviced as soon as possible.
This is normal. The emergency power supply LED will
only light if the primary power supply fails and the unit
takes over powering the switch.

connectors are seated correctly in each port, and that
the correct type of cable is used in each port. See

information.
The GBIC Link LED is not lit. Check the GBIC connector. Make sure the cables are
inserted correctly, with the Transmit (Tx) connector
on one side of the link connected to the Receive (Rx)
connector on the other side of the link.

in the same VLAN
