Install a Rack
Before you install the switch, you must install a standard two- or four-post, 19-inch EIA data center rack (or
a cabinet that contains such a rack) that meets the requirements listed in
Overview of Racks, on page 45 .
Step 1 Bolt the rack to the concrete subfloor before moving the chassis onto it.
Statement 1048
—
Rack Stabilization
Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor
before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over.
Warning
Step 2 If the rack has bonded construction, connect it to the earth ground. This action enables you to easily ground the switch
and its components and to ground your electrostatic discharge (ESD) wrist strap to prevent damaging discharges when
you handle ungrounded components before installing them.
Step 3 Include one or two power sources at the rack. For AC power, provide a power receptacle. For DC power, provide a
circuit breaker with terminals for connecting power cables.
Statement 1018
— Supply Circuit
Take care when connecting units to the supply circuit so that wiring is not overloaded.
Warning
If you are not using power redundancy or are using n +1 redundancy, you need only one power source. If you
are using n + n redundancy, you need two power sources.
