Installing the Switch Chassis
c) Screw in the two captive screws to the chassis and tighten each screw to 8 in-lb (0.9 N·m).
Step 7
If you removed any power supplies before moving the chassis, reinstall each one as follows:
a) Determine which power supply slots to fill and ensure that each of those slots is open.
If you are using the combined or power supply redundancy mode, you can use any slot for the power supply that you
are installing. If you are using the input-source or full redundancy mode, you must group the power supplies that are
to be connected to the same grid on either the left or right power supply slots in the chassis.
b) Place one hand on the front of the power supply and place your other hand under it to support its weight.
c) Align the power supply to an open power supply slot.
The alignment bracket on top of the power supply should align to a track at the top of the slot and a bar at
Note
the bottom of the power supply should be guided by a track at the bottom of the slot.
d) Slide the power supply all the way into the slot until its release handle clicks and the module stops.

Installing the Chassis on a Four-Post Rack or Cabinet

Before You Begin
• Verify that the chassis shipment is complete and undamaged.
• Verify that a rack or cabinet is installed and secured to the subfloor.
• Verify that there is 3 RU (5.25 inches [13.3 cm]) of space above the rails to install the chassis.
• If there are other devices in the rack, verify that the devices that are heavier than this chassis are installed
• Verify that the data center ground is accessible where you are installing the chassis.
Note Fully loaded, the chassis can weigh up to 81.7 lb (37.05 kg). You can lighten the chassis for easier moving
by removing a power supply. To determine the full weight of the chassis and the appropriate weight rating
