Installing the rails
You must install the slide rails before you install the enclosure in a rack.
Procedure
To install the support rails, complete the following steps.
- Refer to the rack configuration planning worksheet, and locate the bottom 1-U of the 2-U space that is marked on the rack vertical frame posts where you will install the enclosure.
- Select the first rail to install. The outer side of each rail is engraved "Left" or "Right."
-
Supporting the rail with one hand, deflect the clip on the bracket slightly
1 and fit the rear bracket into place against the rear vertical rack
rail so that the two pins extend through the upper and lower holes in the 1-U space on the vertical
rail 2 , as shown in the following figure.

To secure the front of the rail to the rack, complete the following steps:
- Locate the numbered 1-U space on the front vertical rail that matches the location of the rear bracket.
- While continuing to support the rail and holding the rear bracket against the rear vertical
frame post 1 , compress or extend the rail far enough to fit the front
rail bracket onto the inner face of the front vertical frame post, while deflecting the latch hook 2 sideways, as
shown in the following figure.

- After the two pins are aligned with the upper and lower holes in the 1-U space on the vertical rail , release the latch hook.
- Fit the locking screw to the back of the rail.

- Slide the inner part of the rail forward until it stops halfway out of the rack.
- Operate the white latch on the inside of the rail to allow the
inner part to be slid further forward and detach.
