Installing the Cisco MDS 9396V Switch
Note
• You connect an AC power supply to the earth ground automatically when you connect the power supply
To ground the switch, perform the following steps:
Before you begin
• Before you can ground the chassis, you must have a connection to the earth ground for the data center
• To connect the switch chassis to the data center ground, you need the following tools and equipment:
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 and use a crimping tool to crimp the
lug to the wire. Verify that the ground wire is securely attached to the grounding lug by attempting to pull the wire out
of the crimped lug.
Step 3
Secure the grounding lug to the chassis grounding pad with two M4 screws and tighten each screw to 11.5 to 15 in-lb
(1.3 to 1.7 N·m) of torque.
Step 4
Prepare the other end of the grounding wire and connect it to an appropriate grounding point in your site to ensure an
adequate earth ground for the switch. If the rack is fully bonded and grounded, connect the grounding wire as explained
in the documentation provided by the vendor for the rack.
The chassis ground connection is active even when the AC power cables are not
connected to the system.
to an AC power source.
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 connecting its grounding pad to the rack. Otherwise, you must connect the chassis grounding
pad directly to the data center ground.
• Grounding lug—A two-holed standard barrel lug that supports up to 6 AWG wire. This lug is
supplied with the accessory kit.
• Grounding screws—Two M4 x 8 mm pan-head screws. These screws are shipped with the accessory
kit.
• Grounding wire—Not supplied with the accessory kit. This wire should be sized to meet local and
national installation requirements. Depending on the power supply and system, a 12 AWG to 6
AWG copper conductor is required for U.S. installations. We recommend that you use commercially
available 6 AWG wire. The length of the grounding wire depends on the proximity of the switch
to proper grounding facilities.
• Number 1 Phillips head torque screwdriver.
• Crimping tool to crimp the grounding wire to the grounding lug.
• Wire stripping tool to remove the insulation from the grounding wire.
