Installing the support rails

You must install the support rails before you install the enclosure in a rack.

To install the support rails, complete the following steps.

1. Refer to the rack configuration planning worksheet, and locate the 1-U space that is marked on the rack vertical frame posts where you will install the enclosure.
2. Select the first rail to install. The outer side of each rail is engraved "Left" or "Right."
3. 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.
   No screws are required.

   

4. To secure the front of the rail to the rack, complete the following steps:
   1. Locate the numbered 1-U space on the front vertical rail that matches the location of the rear bracket.
   2. 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 blue latch hook  2  sideways, as shown in the following figure.

      

   3. 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.
5. Repeat steps 3 and 4 for the opposite rail.
