Cisco Systems 5000 Manual De Usuario

Crimping tool to crimp the grounding wire to the grounding lug. 

Wire-stripping tool to remove the insulation from the grounding wire. 

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. 

For the procedure on how to ground the Cisco Nexus 5000 Series switch chassis, see the 

When installing or replacing the unit, the ground connection must always be made first and 
disconnected last. Statement 1046

We recommend grounding the chassis, even if the rack is already grounded. 

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. 

Statement 1046

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:

Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of 
the grounding cable.

Insert the stripped end of the grounding cable into the open end of the grounding lug.
