Installing the Chassis on a Four-Post Rack or Cabinet

Note
c) Screw in the four captive screws to the chassis and tighten each screw to 8 in-lb (0.9 N·m).
Step 11 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 (that is, place
the power supplies for grid A in slots 1 or 2 or both slots and place the power supplies for grid B in slots 3 or 4 or
both slots).
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.
Note
d) Slide the power supply all the way into the slot until its release handle clicks and the module stops.
