Rack-mounting

25

The air is as free from dust as possible.

The unit is installed in a clean, air conditioned environment.

No more than eight Switch units are placed on top of one another, if 
the units are free-standing.

The Switch is situated away from sources of conductive (electrical) 
dust, for example laser printers.

The AC supply used by the Switch is separate to that used by units 
that generate high levels of AC noise, for example air conditioning 
units and laser printers.

Rack-mounting

The Switch 4400 is 1U high and will fit in most standard 19-inch racks. 

CAUTION:

Disconnect all cables from the Switch before continuing. 

Remove all self adhesive pads from the underside of the Switch if they 
have been fitted.

To rack-mount your Switch:

1

Place the Switch the right way up on a hard flat surface, with the front 
facing towards you.

2

Locate a mounting bracket over the mounting holes on one side of the 
Switch, as shown in Figure 6.
