Installing a Rack or Cabinet
Before you install the switch, you must install a standard four-post, 19-inch EIA data center rack (or a cabinet
that contains such a rack)
Rack and Cabinet Requirements .
Step 1
Bolt the rack to the concrete subfloor before moving the chassis onto it.
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. Note
Statement 1048
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 If you need access to the source power at the rack, include either AC power receptacles or a DC power interface unit
(PIU) with the amperage required by the switch that you are installing. .
If you are using DC power, be sure that the DC power supply is grounded and that there is direct access to the facility
DC power or indirect access though a power interface unit (PIU). You must connect the DC power supply to the earth
ground before you connect it to the facility DC power.
Take care when connecting units to the supply circuit so that wiring is not overloaded.
