No connectivity

Incorrect or bad cable

The following are results of no link
at both ends:

•

A crossover cable was used
when a straight-through was
required, or vice-versa.

•

The cable is wired incorrectly.

•

A crossover or straight-through
cable is wired incorrectly.

•

STP checking for possible
loops.

•

For the correct pinouts and
the proper application of
crossover vs.
straight-through cables, see
the

“Two Twisted-Pair

Cable Pinouts” section on
page B-7

•

Replace with a tested good
cable.

•

For 1000BASE-T
connections, be sure to use
a twisted four-pair,
Category 5 cable.

•

Wait 30 seconds for the port
LED to turn green.

Switch not recognizing a GBIC
module.

Refer to the your GBIC
documentation for more
information.

Unreadable characters on the
management console

Incorrect baud rate.

Reset the emulation software to
9600 baud.
