Port Connection Problems

You can usually trace port connection problems to either a poor cable connection

or an improper connection of the port cables at either end of the link. To remedy

these types of problems, make sure that the cable connections are secure and that

the cables connect to the correct ports at both ends of the link.

Port connection problems are also traceable to the autonegotiation mode or the

port interface.

Note:

Operating temperature for the switch must

not exceed 40°C (104°F). Do not place the switch

in areas where it can be exposed to direct

sunlight or near warm air exhausts or heaters.

The Activity LED for a

connected port is off or

does not blink (and you

have reason to believe

that traffic is present).

The switch is experiencing a

port connection problem.

The switch’s link partner is not

autonegotiating properly.

See “

Port Connection Problems” on page 4-6.

The Status LED is off. A fatal error was detected by

the self-test.

Cycle the power to the switch (disconnect and

then reconnect the AC power cord).

If the problem persists, replace the switch.

The Status LED is

blinking.

A nonfatal error occurred

during the self-test.

Cycle the power to the switch (disconnect and

then reconnect the AC power cord).

If the problem persists, contact the Nortel

Networks Technical Solutions Center.
