VIAVI Rail Kit
This rail kit is for 2U and 4U appliances.
Decide on a suitable location for the rack unit that will hold your chassis. It should be a clean, dust-free area that is well ventilated. Avoid areas where heat, electrical noise and electromagnetic fields are generated. A nearby grounded power outlet is required.
How to attach the rails
Rail assemblies must be attached to the chassis and rack before inserting the system into your rack.
The box your chassis was shipped in should include:
two sets of rail assemblies
two rail mounting brackets
mounting screws and washers to mount the system into the rack
This rail will fit a rack between 26.5" and 36.4" deep.
1. Identify the inner rack rails.
The chassis package includes one pair of rack rail assemblies in the rack mounting kit. Each assembly consists of an inner rail that secures to the chassis and an outer rail that is attached directly to the rack. The inner rails are etched with “L” (Left side) and "R" (Right side). The rail is on the correct side and mounted correctly if the lettering if face-up.

2. Identify the left and right side inner rails. Place the correct inner rail on the side of the chassis, aligning the hooks of the chassis with the inner rail holes. Make sure the rail faces "outward" so that it will fit with the rack's mounting bracket.
3. Slide the rail toward the front of the chassis to hook the inner rail onto the side of the chassis.
4. If desired, secure the rail with two flat head M4 x 4mm screws (and washers) as illustrated.
5. Repeat for the other inner rail.

6. Identify the outer rack rails.
7. Press upward on the locking tab at the rear end of the middle rail.
8. Push the middle rail back into the outer rail.
9. Hang the hooks on the front of the outer rail onto the square holes on the front of the rack. If desired, use screws (and washers) to secure the outer rails to the rack.
10. Pull out the rear of the outer rail, adjusting the length until it just fits within the posts of the rack.

11. Hang the hooks of the rear section of the outer rail onto the square holes on the rear of the rack. Take care that the proper holes are used so the rails are level. If desired, use screws (and washers) to secure the rear of the outer rail to the rear of the rack.
12. Repeat for the other outer rail.
The rails are attached.
Next, insert the server into the rack.
How to install the system into your rack
This section provides information on installing a chassis into a rack unit with the rails provided. There are a variety of rack units on the market, so the assembly procedure may differ slightly. Also refer to the installation instructions for your rack unit.
Caution: Do not pick up the server by the front handles. They are designed to pull the system from a rack only.
1. Align the chassis rails with the front of the rack rails.
2. Slide the chassis rails into the rack rails, keeping the pressure even on both both sides. You may have to depress the locking tabs while inserting. When the server has been pushed completely into the rack, the locking tabs should "click" into the locked position.
3. If screws are used, tighten the screws on the front and rear of the outer rails.
4. Insert and tighten the thumbscrews that hold the front of the server to the rack.
How to remove the server from the rack
Caution: It is dangerous for a single person to off-load the heavy chassis from the rack without assistance. Be sure to have sufficient assistance supporting the chassis when removing it from the rack. Use a server lift.
1. Pull the chassis forward out the front of the rack until it stops.
2. Press the release latches on each of the inner rails downward simultaneously and move the chassis forward in the rack.
