Rack-mounting 21

If the Switch is installed in a 19-inch rack or closed assembly its local air temperature may be greater than room ambient temperature.

■ The air is as free from dust as possible.

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

	■ The unit is installed in a clean, air conditioned environment.
	■ 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.
	■ No more than eight Switch units are placed on top of one another, if
	the units are free-standing.

Rack-mounting	The Switch 4200 Family are 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 5.
