If it does not, the problem may be with the cabling
between the devices, the connectors on the cable,
the normal operation of protocols, such as Spanning
Tree, LACP, or GVRP features.
or the configuration of the device on the remote end
of the cable.
• Use the switch console to check the port’s
configuration to confirm whether the port is
administratively disabled or placed in a “blocking”
state by the normal operation of one or more
protocols.
◦ Check the Port Status using the show interfaces
command to confirm whether the port is
configured as “disabled”.
◦ Review the switch configuration to confirm which
protocols are operating on the port. Use the
appropriate feature show commands to confirm
whether the port is put into a “blocking” state.

light is still blinking, replace the power supply.
Check to ensure the fans are functioning correctly. See
Environmental for more information.
