Installing the Switch Chassis
Step 5
Use six screws (user preference from the accessory kit) at the front and four M3 screws at the back of the slide to secure
the system chassis to the four-post rack
Figure 4: Attaching the Chassis to the Rack
1 Install six screws (user preference from the accessory
kit) at the front.
Step 6 If you removed the fan tray before moving the chassis, reinstall each one in the chassis as follows:
a) Holding each of the two handles on the fan tray with your two hands, align the fan tray to an open fan tray slot.
Note The two alignment brackets on top of the fan tray should align to two tracks at the top of the 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 left and the right) should go into holes in the chassis and
the two captive screws on the fan tray should align to screw holes in the 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 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.
