Installing the system into the rack (option A: Drop-In)

1. Pull the inner rails out of the rack until they lock into place.
2.  Locate the rear rail standoff on each side of the system and lower them into the rear J-slots on the slide assemblies.
3.  Rotate the system downward until all the rail standoffs are seated in the J-slots.
4. Push the system inward until the lock levers click into place.
5. Pull the blue slide release lock tabs forward on both rails and slide the system into the rack until the system is in the rack.

Securing or releasing the system

1. To secure the system, push the system into the rack until the slam latches engage and lock into the rack.
NOTE: To secure the system for shipment in the rack or in other unstable environments, locate the hard mount captive screw under each latch and tighten each screw using a Phillips #2 screwdriver.
2. Release the system from the rack by lifting the slam latches and sliding the system out of the rack.
NOTE: If applicable, use a Phillips #2 screwdriver to unscrew the captive screws that secure the system to the rack.

Securing rails to the rack

To secure the rails to the rack for shipping or in unstable environments, install the supplied screws to the rails.
NOTE : For square hole racks, install the supplied conical washer to the screw before installing the screw.
NOTE : For unthreaded round hole racks, install only the screw without the conical washer.
Align the screws with the designated U spaces on the front and rear rack flanges.
NOTE : Ensure that the screw holes on the tab of the system retention bracket are seated on the designated U spaces.
Insert and tighten the two screws using the Phillips #2 screwdriver to secure the rails to the rack.

Routing the cables

NOTE: To install the Cable Management Arm (CMA), refer to the document shipped with your CMA.

If you did not order the CMA, use the two straps provided in the rail kit to route and secure the cables at the back.
1. Locate the CMA bracket slots on the rear end of both rails.
2. Bundle the cables gently, pulling them clear of the system connectors to the left and right sides.
NOTE : Ensure that there is enough space for the cables to move when you slide the system out of the rack.
3. Thread the straps through the CMA bracket slots on each side of the system to hold the cable bundles.
