Unpack and Install the Chassis
Warning
Statement 1046 Installing or Replacing the Unit
To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be
made first and disconnected last.
If your unit has modules, secure them with the provided screws.
Warning
Statement 2004 Grounded Equipment
This equipment is intended to be grounded to comply with emission and immunity requirements. Ensure that
the switch functional ground lug is connected to earth ground during normal use.
Note
Statement 7015 Equipment Bonding and Grounding
When you use thread-forming screws to bond equipment to its mounting metalwork, remove any paint and
nonconductive coatings and clean the joining surfaces. Apply an antioxidant compound before joining the
surfaces between the equipment and mounting metalwork.
Caution
Grounding the chassis is required, even if the rack is already grounded. A grounding pad with two threaded
holes is provided on the chassis for attaching either a grounding lug or grounding plate. The ground lug must
be NRTL-listed. In addition, a copper conductor (wires) must be used and the copper conductor must comply
with NEC code for ampacity.
Caution
When terminating the frame ground, do not use soldering lug connectors, screwless (push-in) connectors,
quick connect connectors, or other friction-fit connectors.
Procedure
Step 1
Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of the
#6 AWG grounding cable.
Step 2
Insert the stripped end of the grounding cable into the open end of the grounding lug.
Step 3
Use the crimping tool to secure the grounding cable in the grounding lug.
Step 4
Attach the ground cable. Attach one end of the shelf ground cable (#6 AWG cable) to the ground lug extension
bracket using the specified dual-hole lug connector.
Step 5
Attach the ground lug extension bracket to the chassis.
