Problems

SNMP fan fail trap hardware failure

In the rare event of your Switch unit experiencing an SNMP fan fail trap
hardware failure, refer to the suggested solution below.

1

Power off the unit.

2

Check that the air vents are not obstructed.

3

Power cycle the unit. To do this, remove and reconnect all power supplies.

4

If a further fan fail trap is received, return the unit.

Error message indicating that the GBIC transceiver is invalid

The Switch has identified that the GBIC does not meet the minimum
requirements for the Switch and has disabled the port. To correct this
problem, completely remove the GBIC and replace it with a 3Com
approved GBIC. See

“Approved GBIC Transceivers”

on

page 27

.

Error message indicating that the GBIC transceiver is faulty

To correct this problem, completely remove the GBIC and then reinsert it.
If the problem persists, contact 3Com Technical Support.

Solving
Communication
Problems

If you experience communication problems with the Switch, ensure that:

■

The Switch IP address has been configured as described in

Chapter 3

■

If the Switch is separated from your management application by a
router, ensure that the default gateway IP address within the Switch is
the same as the IP address of the router.

■

The Switch’s IP address has been entered correctly in your network
management application (such as 3Com Network Supervisor).

The following is a brief overview of IP addressing, and how to obtain a
registered IP address.

IP Addressing

To be managed correctly, each device on your network (for example a
Switch or Hub) must have a unique IP address. IP addresses have the
format

n.n.n.n

where

n

is a decimal number between 0 and 255. An

example IP address is 192.168.100.8.
