Fitting a bracket for rack-mounting

3

Insert the two screws and tighten with a suitable screwdriver.

You must use the screws supplied with the mounting brackets. Damage 
caused to the unit by using incorrect screws invalidates your warranty.

4

Repeat steps 2 and 3 for the other side of the Switch.

5

Insert the Switch into the 19-inch rack and secure with suitable screws 
(not provided). Ensure that ventilation holes are not obstructed.

6

Connect network cabling.

7

Finally place a unit information label on the unit in an easily accessible 
position. The unit information label shows the following:

■

The 3Com product name of the Switch

■

The 3Com 3C number of the Switch

■

The unique MAC address (Ethernet address) of the Switch

■

The serial number of the Switch

You may need this information for fault reporting purposes.
