Installing a Chassis
Tip
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).
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 six 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 12 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 is grounded when you connect the chassis and the power supplies to the earth ground in the
following ways:
• You connect the chassis (at its grounding pad) to either the data center ground or to a fully-bonded and
• You connect the AC power supplies to the earth ground automatically when you connect an AC power
Statement 1046—Installing or Replacing the Unit
Warning
When installing or replacing the unit, the ground connection must always be made first and disconnected
last.
Before You Begin
Before you can ground the chassis, you must have a connection to the earth ground for the data center 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.
To connect the switch chassis to the data center ground, you need the following tools and materials:
