Chapter2 Installing the Cisco Nexus 5000 Series Switches
Grounding the Switch
•Crimping tool to crimp the grounding wire to the grounding lug.
•Wire-stripping tool to remove the insulation from the grounding wire.
Grounding the Cisco Nexus 5500 Series Chassis
The chassis has a grounding pad with two threaded M4 holes for attaching a grounding lug. The location
of the system ground on the Cisco Nexus 5500 Platform switches is identical to that on the Cisco Nexus
5000 Platform switches.
Note For the procedure on how to ground the Cisco Nexus 5000 Series switch chassis, see the “Grounding the
Cisco Nexus 5500 Series Chassis” section on page2-22.
Warning
When installing or replacing the unit, the ground connection must always be made first and
disconnected last.
Statement 1046
Caution We recommend grounding the chassis, even if the rack is already grounded.
Caution All power supplies must be grounded. The receptacles of the AC power cables used to provide power to
the chassis must be the grounding type, and the grounding conductors should connect to protective earth
ground at the service equipment.
Warning
When installing or replacing the unit, the ground connection must always be made first and
disconnected last.
Statement 1046
Caution Grounding the chassis is required if you are using DC power supplies, even if the rack is already
grounded. A grounding pad with two threaded M4 holes is provided on the chassis for attaching a
grounding lug. The ground lug must be NRTL listed. In addition, the copper conductor (wires) must be
used and the copper conductor must comply with NEC code for ampacity.
To attach the grounding lug and cable to the chassis, follow these steps:
Step1 Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of
the grounding cable.
Step2 Insert the stripped end of the grounding cable into the open end of the grounding lug.
