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.

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 

on 

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

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

■

The Switch IP address has been configured as described in 

■

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.

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.
