  • Switch Cards

Leave the chassis on the pallet until you are ready to move and install the chassis in a rack.

What to do next:

Attach bottom support rails to the chassis

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 16 RU (28 inches [71.12 cm]) for 8608 chassis of vertical space above support rails.

Step 2

Attach the bottom-support rail to the rack by using a Phillips torque screwdriver. Use the M6 x 19 mm or 12–24 x 3/4 inch screws for each end of the buttom-support rails and tighten each screw to 40 in-lbs (4.5 N-m) of torque.

Grounding lug and screws

To accommodate equipment racks with different mounting hole patterns, the chassis mounting brackets have groups of screw holes on either side. The mounting holes in the chassis mounting brackets are spaced so that one mounting hole in each hole group aligns with a corresponding hole in the equipment rack. By using the corresponding mounting hole (in the same hole group) on the opposite side of the chassis, you can level the chassis in the rack.


Note
To lift the chassis, use a mechanical lift. Do not use the handles on the side of the chassis. Use the side handles only for repositioning the chassis after it is already on the mechanical lift or in the rack or cabinet.

Warning
