Rack Mounting the SSA in a Two-post Rack (3-inch Posts)

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.

In a two-post rack with 3-inch posts, three mid-mount positions are possible. See Installation Positions in a Two-post Rack (3-inch Posts) for possible mounting positions, as shown on the right post. We recommend the top mid-mount position as the best of the three options.

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 rails or the SSA to the rack posts.

Installation Positions in a Two-post Rack (3-inch Posts)

To rack mount the SSA in a two-post rack with 3-inch posts, follow these steps:

1. Remove the extensions from each rack rail by unscrewing the rail clamps.
   See Removing the Rail Extensions.
2. Using the eight 6-32 screws removed in step 1, attach the mounting bracket to each rail (four screws for each mounting bracket) in the appropriate orientation for the mounting option that you have chosen.
   See Installation Positions in a Two-post Rack (3-inch Posts).
3. Secure the mounting brackets to the rack posts with three customer-supplied screws in each mounting bracket.
   Depending on the mounting option, you must secure the mounting brackets to either the front or back of the rack posts. See Installation Positions in a Two-post Rack (3-inch Posts).

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

4. Snap the 10-32 cage nuts, included in the SSA rail kit, into the square screw holes on the front mounting ears of the rails.
5. Slide the SSA onto the rails until the front of the SSA is against the mounting ears of the rails.
6. Secure the front of the SSA to the rails by screwing the 10-32 screws, included in the SSA rail kit, into the mounting ears on the right and left front of the SSA.
7. Secure the rear of the SSA to the rails.
   See Securing the SSA to the Rear of the Rails.
