Grounding the Chassis

If the bottom-support rails are extended a long distance, they can bend outwards slightly when you install the

Note

chassis and the chassis stops at the far end of the rails might not fit into the end of the chassis. If this happens,

press the side rails toward the sides of the chassis so that the chassis stops can go inside the chassis and hold

it in place on the rack.

Slide the power-supply end of the chassis onto the

bottom-support rails so that the chassis locks onto the

chassis stops at the end of the rails.

Chassis stops for holding the chassis (positioned by

the aisle required for the fan and power supply

modules).

Step 2

Use a customer-supplied rack-mount screw (an M6 x 10 mm screw or other appropriate screw for the rack) to attach each

of the two mounting brackets on the chassis to the rack and tighten each screw to the appropriate torque setting for the

screw (for M6 x 10 mm screws, use 40 in-lbs [4.5 N·m] of torque).

The switch chassis is automatically grounded when you properly install the switch in a grounded rack with

metal-to-metal connections between the switch and rack.

You can also ground the chassis, which is required if the rack is not grounded, by attaching a customer-supplied

grounding cable. Attach the cable to the chassis grounding pad and the facility ground.
