When mounting the switch in a rack, ensure that the 19-inch rack meets the
following standard specifications:
ANSI/EIA RS-230 Standard, entitled Cabinets, Racks, Panels, and
Associated Equipment
MIL-STD- 189, entitled Racks, Electrical Equipment, 19-Inch and Associated
Panels
The brackets shown in Figure 4-2 are provided with the switch so that the switch
can be secured on a shelf. The brackets alone are not designed to support the
weight of the switch.
CAUTION!
If the switch is mounted in a closed or multi-unit rack
assembly, make sure that the operating temperature inside the
rack enclosure does not exceed the maximum rated ambient
temperature. Refer to ”Environmental” on page A-4.
The switch must rest on rails or a shelf in the rack or cabinet.
Allow 16 cm (6.5 in) minimum clearance at the front and rear of
the rack for service access and ventilation.
Do not restrict chassis air flow. Allow 16 cm (6.5 in) minimum
clearance at the front and rear of the rack for service access and
ventilation.
Multiple rack-mounted units connected to the AC supply
circuit may overload that circuit or overload the AC supply
wiring. Consider the power source capacity and the total power
usage of all switches on the circuit. Refer to ”Electrical” on
page A-3.
Reliable grounding in the rack must be maintained from the
switch chassis to the AC power source.
