How to Install the Express Slide Rails Onto the Server and the Rack

Note - The express slide rail kit comes with the 4U Express Rail Rackmounting Kit card that contains illustrations that you should refer to during this procedure. It can also be used to block out the 4 unit (4U) space to be occupied by the server.

Attach the mounting brackets to the server.
Each mounting bracket has a flat side, which fits against the server chassis. The other side has a pair of rims that fit into the slide rails. Each bracket has 6 key-shaped holes which fit over the pins on the side of the server.

Note - The last (rear-most) hole is not used.
1. Position a bracket so that the green lock levers are at the front of the server and the holes on the bracket are over the pins on the server.
2. Hang the bracket on the pins.
  The middle of the bracket will bow out slightly so that the middle hole does not engage.
3. Press down on the center of the bracket and slide forward.
  All 5 pins should lock into place with an audible click.
4. Repeat the above steps with the other bracket.
Use the installation card to determine the 4U space that will be occupied by the server.
The slide rails cover the holes on the 2U space on the bottom of the 4U space that is occupied by the server.
The installation card is designed so that it exactly covers a 4U space in the rack. The lower half of the card is narrower than the rest, so that the holes used by the slide rails are visible.
(Optional for securing the server and slide rails for shipping) If you plan to ship the server and slide rails in place and you have a rack with square holes, place cage nuts in the holes at the top and the bottom of the 2U slide rail space. It is not possible to install the cage nuts after the slide rail is installed.
Tip - Install the cage nuts if you plan to ship the server in the future.

From behind the rack post, put the bottom tab of the cage nut into the hole and squeeze the top tab into the hole.

Note - In normal installation, securing is not required. Securing provides extra stability in special circumstances, such as shipping the server in place, that is, shipping the server mounted in the rack and then shipping the rack.
Attach the slide rails to the rack.
Each slide rail has an attachment assembly at either end. Each assembly has two pins that fit into the rack holes (either round and square) and a spring that holds the rack rail against the assembly. The front part of the rail is stamped with the word “FRONT.” The rear part of the rail is stamped with the word “REAR.”
1. Orient the slide rail with the ball bearing track at the front of the rack.
2. Extend the slide rail to the length of the rack.
3. Slide the front attachment assembly over the rack’s posts, so that the pins fit into the rack holes. Push the assembly into the rack post until it clicks into place.
4. Insert the rear attachment assembly into the holes of the rack post.
  Tip - Press the gray plastic tabs toward the rack post to adjust the length of the slide rails.
5. Repeat the above steps with the other slide rail.
