Corrective action
Verify that each AC power cord is
fastened securely at both ends and
that power is available at each AC
power outlet. Plug in a device such as
a lamp to ensure that the power outlet
is operational. Verify that each power
supply is turned on.
Verify that the cable connections to
the link partner are correct. Verify port
configuration parameters for both ends
of the connection. Move the cable
to another port to see whether the
problem occurs on the new port.
Verify port configuration parameters
for both ends of the connection.
