If a fault does occur, refer to the Installation Guide to ensure that the 

problem you encountered is actually caused by the switch. If the problem 

appears to be caused by the switch, follow these steps:

1.

Enable logging. 

2.

Set the error messages reported to include all categories. 

3.

Enable SNMP.

4.

Enable SNMP traps.

5.

Designate the SNMP host that is to receive the error messages. 

6.

Repeat the sequence of commands or other actions that lead up to the 
error. 

7.

Make a list of the commands or circumstances that led to the fault. Also 
make a list of any error messages displayed. 

8.

Contact your distributor’s service engineer.
