Installing a Rack or Cabinet
Before you install the Cisco Nexus 7004 chassis, 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 the Cisco Nexus
7000 Series Site Preparation Guide. To maximize safety, you should do the following for the rack:
• Bolt the rack to the concrete subfloor before moving the Cisco Nexus 7004 chassis onto it.
Warning
• If the rack has bonded construction, connect it to the earth ground to enable you to easily ground the
Be sure that the rack includes AC power receptacles with the amperage required for the power supplies that
you will be installing in the chassis. For 3-kW power supplies, you must have 20-A circuits.
