Bottom support rails4Chassis mounting brackets.2
To adjust the placement of the chassis on the bottom-support rails, you can use the chassis handles, see Callout
1 in the following figure.
Tip
Step 5 If the mechanical lift is raised above the height of the bottom-support rails, gently lower it to the level of the rails or no
more than 1/4 inch (0.6 cm) below the rails.
This action helps to prevent the bottom of the chassis from getting caught on the expansion edges of the bottom-support
rail.
Step 6 Push the chassis all the way onto the rack so that the vertical mounting brackets on the front of the chassis come in contact
with the vertical mounting rails on the rack.
Step 7 Use four M6 x 19 mm or 24 x 3/4-inch screws to attach each of the two chassis vertical mounting brackets to the two
rack vertical mounting rails (total of 8 screws) as shown in the following figure.
Four M6 x 19 mm or 10-24 x 3/4 in. Phillips screws used to attach each
side bracket to a front mounting rail (use a total of eight screws).

What to do next
After you have secured the chassis to the rack, you can connect the chassis to the data center ground.
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.
