Rack Mounting the SSA in a Four-post Rack

For a four-post rack installation, the SSA rail kit requires that the front to back spacing of the rack posts be within the range of 24.5 to 32.5 inches (62.3 to 82.5 cm).

In a four-post rack, the SSA is flush-mounted on the rails supplied in the SSA rail kit and secured to the front posts of the rack. You can optionally secure the rear of the SSA to the rails.

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.

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.

To install the SSA in a four-post rack, follow these steps.

1. Extend the right and left rails to fit the outside dimensions of the rack posts.
   The rails in the SSA rail kit are shipped with the rail extensions attached. If the rails do not slide easily, loosen the screws that secure the rail extensions to the main rails.
2. 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.
3. Attach each rail to the rack posts with two screws in the front and two screws in the back in the top and bottom screw holes.
   See Attaching the Rails to a Four-post Rack. The SSA rail kit does not include screws for attaching the rails to the rack posts.

4. If necessary, tighten the screws that secure the rail extensions to the rails.
   These screws must be tight before you place the SSA in the rails.
5. From the front of the rack, slide the SSA onto the rails until the mounting ears of the SSA are against the front posts of the rack.
6. 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.
