Unpack and Install the Chassis
• 16 x M4 screws from the 8808 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 router 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 21 RU (36.75 inches [93.34 cm]) for 8812 chassis and 16 RU (28 inches [71.12 cm])
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.

Note
for 8808 chassis of vertical space above support rails.
Use at least three screws on each end of each bottom-support rail.
