  2.  Position the rail end piece labeled FRONT facing inward and orient the rear end piece to align with the holes on the rear rack flanges.
  3. Push the rail straight toward the rear of the rack until the latch locks into place.
  4. For the front end piece, rotate the latch outward and pull the rail forward until the pins slide into the flange, and release the latch to secure the rail in place.
  5.  Repeat the preceding steps to install the right rail.

2. Pull the entire rail forward to release the rear end of the rail from the flange.

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.

Installing the system into the rack (Option B: Stab-In)

  1. Pull the intermediate rails out of the rack until they lock into place.
  2.  Release the inner rail lock by pulling forward on the white tabs and sliding the inner rail out of the intermediate rails.
  3.  Attach the inner rails to the sides of the system by aligning the J-slots on the rail with the standoffs on the system and sliding forward on the system until they lock into place.

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.
