Unpack and Install the Chassis
Figure 6: Remove Shipping Brackets from the Chassis
Remove the shipping brackets:
• 16 x M4 screws from the chassis
To make the chassis weigh less for moving, remove the following module and place them where their connectors
will not be damaged:
• Fan trays
Leave the chassis on the pallet until you are ready to move and install the chassis in a rack.

Install Bottom-Support Rails

The bottom-support rails support the weight of the chassis in the rack. To maximize the stability of the rack,
you must attach these rails at the lowest possible rack unit (RU).
Procedure
Step 1
Position the vertical rack rails at 32" depth to match with the length of the bottom-support rails. Check spacing
considerations.
• Maintain at least 16 RU (28 inches [71.12 cm]) for 9808 chassis of vertical space above support rails.
Step 2
Attach the bottom-support rail to the rack using a Phillips torque screwdriver on M6 x 19 mm or 12–24 x 3/4
inch screws for each end of the rail (as shown in the following figure) and tighten each screw to 40 in-lbs (4.5
N-m) of torque.
