Rack Mounting the SSA in a Two-post Rack (7-inch Posts)

In a two-post rack with 7-inch posts, the SSA is flush-mounted in the rack and secured in the SSA rails to the front and rear of the posts. In this procedure, you need to modify the rails by removing the rail extensions and attaching the mounting brackets, which are supplied in the rail kit.

Caution

If you are installing an SSA in a four-post or two-post rack, you must use the SSA rail kit to install the SSA in the rack. Do not attempt to secure the SSA directly to the rack using the small front mounting ears.

Precaución: Si instala un SSA en un estante de cuatro o de dos postes, debe usar el kit de rieles de SSA para realizar la instalación. No intente asegurar el SSA directamente en el estante usando las lengüetas de montaje delanteras pequeñas.

Note

If you plan to secure the rear of the SSA to the rails, you must remove the screw in the left rear corner of the SSA BEFORE you install the SSA in the rack. For more information, see Securing the SSA to the Rear of the Rails.

The SSA rail kit does not include screws for attaching the mounting brackets to the rack posts.

To rack mount the SSA in a two-post rack with 7-inch posts, follow these steps:

1. Remove the extensions from each rail by unscrewing the rail clamps.
   See Removing the Rail Extensions.

   The rail extensions and rail clamps are not used to install an SSA in a two-post rack. Save the eight 6-32 screws to be used in the next step.

   

   Removing the Rail Extensions

   

   1 = Rails (used in this procedure)	3 = Rail clamps (not used in this procedure)
   2 = Rail extensions (not used in this procedure)	4 = 6-32 screws (used in this procedure)

2. Attach a mounting bracket, included in the SSA rail kit, to the outside of each rail using the 6-32 screws you removed in step 1.
   See Attaching the Mounting Brackets to the Rails (Left Rail Example).

   Use four 6-32 screws to attach each mounting bracket. Leave the 6-32 screws loose to position the mounting brackets properly against the rack posts.

   

   Attaching the Mounting Brackets to the Rails (Left Rail Example)

   

   1 = Mounting bracket

   2 = Rail

3. Position the right and left rails, which are labeled on the inside of each rail, in the rack with the bottom lip of the rail facing into the rack.

   The front mounting ears of the rails should be flush against the front screw holes of the rack posts. The mounting brackets should be flush against the rear screw holes of the rack posts. See Positioning and Attaching the Rails to the 7-inch Posts.

   2 = Securing the left mounting bracket to the rear of the 7-inch post

4. Attach the rails to the rack posts.
   See Positioning and Attaching the Rails to the 7-inch Posts.
   1. Secure the front of the rail to the front of the rack post with customer-supplied screws in the top and bottom screw holes.
   2. Secure the mounting bracket to the back of the rack post with customer-supplied screws in the top and bottom screw holes.
      The SSA rail kit does not include screws for attaching the rails and mounting brackets to the rack posts.
5. Tighten the 6-32 screws that secure the mounting brackets to the rails.
6. Slide the SSA onto the rails until the front of the SSA is against the front of the rack posts.
7. Secure the front of the SSA to the rack by screwing the customer-supplied rack screws in the mounting ears on the right and left front of the SSA.
8. Secure the rear of the SSA to the rails.
   See Securing the SSA to the Rear of the Rails.
