Step 10 If you removed any fan trays before moving the chassis, reinstall each one in the chassis as follows:

slot.
b) Slide the fan tray into the slot until the front of the fan tray comes in contact with the rear of the chassis.
Note The two alignment pins on the fan tray (on the top and one on the bottom) should go into holes in the chassis
and the four captive screws on the fan tray should align to screw holes in the chassis.
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.
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.
