Rack-mounting
23
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.
■
No more than four Switch units are placed on top of one another, if
the units are free-standing.
Rack-mounting
The Switch 3870 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.
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:
1
Place the Switch the right way up on a hard flat surface, with the front
facing towards you.
2
Locate a securing bracket over the mounting holes on one side of the
Switch, as shown in
Figure 4
.
3
Insert the four screws and tighten with a suitable screwdriver.
