Rackmounting IRUs with Shelf Rails

This section describes how to rackmount an IRU using shelf rails. The shelf rails, which are shipped with the module, support the module within the rack. To attach the shelf rails to the rack, follow these steps:

1.Locate the slot location in the rack in which you will install the IRU. See “Determining Where to Attach Rails in a Rack” on page 25 if you are uncertain.

2.In the slot location from step 1, position the left shelf rail at a 90-degree angle to the front and rear rack rails (see Figure 1-12).

3.Insert the top-front bracket tab into one of the narrow slots in the front rack rail.

4.Insert the top-rear bracket tab into the narrow slot in the rear rack rail.

Note: Verify that the tabs are the same height to ensure that the shelf is level in the rack.

5.Lower the bottom of the shelf rail until its two lower tabs engage with the wide slots in the front and rear rack rails. The shelf rail is held in by gravity and the tabs.

6.Repeat these steps for the right shelf rail.
