Solutions
The Power LED is not lit.
LED will turn off during system initialization. Check
the power connection. Plug the power cord into
another known working AC outlet.
The primary power supply has failed. Install the
optional emergency power supply and have the
primary power supply serviced as soon as possible.
The Emergency Power LED is not lit.
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.

Check the cable connections. Make sure the
connectors are seated correctly in each port, and that
the correct type of cable is used in each port. See
Chapter 2.6: Connecting to the Network
for more
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.

device (switch, router, workstation, etc.).
