Rack-mounting

■

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.

■

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

Rack-mounting

The Switch 40x0 is 2U 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.

CAUTION:

If you use a shelf or support ensure that it will not obstruct

the air flow through the side panels of the Switch.

To rack-mount your Switch:

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

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

Figure 5

Insert the four screws and tighten with a suitable screwdriver.
