Rack-Mounting - 3Com SuperStack 3 Getting Started Manual

Rack-mounting

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.
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.
