Receiving hole on each side of the chassis for the
chassis stops on the bottom-support rails.

3

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.

1

Customer-supplied rack-mount screw (M6 x 10 mm
screw or other screw appropriate for the rack) used to
secure each side of the chassis to the rack.

4

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).

Grounding the Chassis

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.
