Required Tools And Equipment - Cisco Nexus Hyperfabric HF6100-32D Installation Instructions Manual

Required tools and equipment

To connect the system ground, you need the following tools and materials:
• Grounding lug — When using the double-hole lug connector provided with the system, the ground wire must be 6 AWG only.
Otherwise, a supported closed-loop ring connector must be used for 8-14 AWG wire.
• Grounding screws — Two M4.0 x 6mm Phillips pan-head screws. Supplied as part of the accessory kit.
• Grounding wire — Not supplied as part of accessory kit. The grounding wire should be sized according to local and national
installation requirements. For U.S. installations, AC power supply systems require a 14 AWG copper conductor. Commercially
available 8-14 AWG wire is recommended. DC power supply systems with 930W power supply module require a 12 AWG wire
and 1500W power supply module require a 8 AWG wire. The length of the grounding wire depends on the proximity of the
switch to proper grounding facilities.
• Number 1 and number 2 Phillips screwdrivers with torque capability to rack-mount the chassis.
• 3/16-inch flat-blade screwdriver.
• Tape measure and level.
• ESD wrist strap or other grounding device.
• Antistatic mat or antistatic foam.
• Two-hole ground lug (1).
• Grounding cable sized according to local and national installation requirements; the required length depends on the proximity
of the switch to proper grounding facilities. Cisco provides a 6 AWG lug.
• Crimping tool for lug.
• Wire-stripping tool.
• M4 screws to fix brackets (16).
• M4 screws to fix a ground lug (2).
Connect the switch to the ground
To establish an earth ground for the chassis, you must attach a grounding cable from the chassis' grounding lug to the rack.
Step 1
Use a wire-stripping tool to remove approximately 0.75 inch (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.
Step 3
Crimp the grounding wire in the barrel of the grounding lug. Verify that the ground wire is securely attached to the ground
lug.
Step 4 Place the grounding wire lug against the grounding pad on the switch, making sure that there is solid metal-to-metal
contact.
You can install the grounding lug on the left or the right side of the chassis; the grounding pad are located on the sides
of the chassis.
Step 5
Before you secure the lug to the chassis, make sure that the grounding lug and the grounding wire do not interfere with
other switch hardware or rack equipment. Secure the grounding bracket and the lug to the chassis with two M4.0x 6mm
flat-head screws.
