Grounding the Chassis
Statement 1024—Ground Conductor
Warning
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority
or an electrician if you are uncertain that suitable grounding is available.
Statement 1046—Installing or Replacing the Unit
Warning
When installing or replacing the unit, the ground connection must always be made first and disconnected
last.
Before You Begin
Before you can ground the chassis, you must have a connection to the earth ground for the data center building.
If you installed the switch chassis into a bonded rack (see the rack manufacturer's instructions for more
information) that now has a connection to the data center earth ground, you can ground the chassis by installing
it into the rack. Otherwise, you must connect the chassis grounding pad directly to the data center ground.
Step 1 Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of the grounding
wire.
Step 2 Insert the stripped end of the grounding wire into the open end of the grounding lug, and use a crimping tool to crimp
the lug to the wire (see Callout 2 in the following figure). Verify that the ground wire is securely attached to the grounding
lug by attempting to pull the wire out of the crimped lug.
