The Switch is suited for use on a desktop, either free standing or 
mounted in a standard 19-inch equipment rack. Alternatively, the Switch 
can be mounted in a wiring closet or equipment room, as an aggregator 
for other Hubs and Switches. A rack-mounting kit containing two 
mounting brackets is supplied with the Switch.

When deciding where to position the Switch, ensure that:

■

Cabling is located away from:

■

sources of electrical noise such as radios, transmitters and 
broadband amplifiers. 

■

power lines and fluorescent lighting fixtures

■

The Switch is accessible and cables can be connected easily.

■

Water or moisture cannot enter the case of the Switch.

■

Air flow is not restricted around the Switch or through the vents in the 
side of the Switch. 3Com recommends that you provide a minimum of 
25mm (1in.) clearance.

■

Air temperature around the Switch does not exceed 40 

°C

 (104 

°

F).
