Installing the support rails for the 2145-24F or 2145-12F expansion enclosure

Edit online

Before you install a 2145-24F or 2145-12F expansion enclosure, you must first install the support rails.

Procedure

To install the support rails, complete the following steps:

  1. Locate the rack mounting rails and screws (Figure 1).
    The rail assembly consists of two rails that must be installed in the rack cabinet.

  2. Remove the springs that are taped to one of the rails.
  3. Attach a spring to the outside of each rail.
    1. Attach the circle end of the spring around the stud on the rail (see Figure 2).
    2. Pulling on the spring, attach the hook end of the spring to the tab on the rail.

  4. Working at the front of the rack cabinet, identify the two standard rack units (2U) of space in the rack into which you want to install the support rails.
    Figure 3 shows two rack units with the front mounting holes identified.

    This figure shows the hole locations in the front of the rack when installing the rails.
    •  1  Upper rail mounting bracket pin
    •  2  Lower rail mounting bracket pin
    •  3  Rack mounting screw hole
    Note: Each rail comes with two medium bracket pins in the front bracket and two medium bracket pins in the rear bracket. The medium bracket pins are for installation in a 19-inch IBM® rack cabinet. If you are installing the storage enclosure in a non-IBM rack cabinet, you might need to replace the set of medium bracket pins on the front and rear of the rail with either the small or large bracket pins that are included in the rail kit.
  5. At each end of the rail, grasp the tab  1  and pull firmly to open the hinge bracket (see Figure 4).

  6. Align the holes in the rail bracket with the holes on the front and rear rack cabinet flanges. Ensure that the rails are aligned on the inside of the rack cabinet.
  7. On the rear of the rail, press the two bracket pins into the holes in the rack flanges and close the rear hinge bracket to secure the rail to the rack cabinet flange (see Figure 5).

  8. On the front of the rail, press the two bracket pins into the holes in the rack flanges and close the front hinge bracket to secure the rail to the rack cabinet flange (see Figure 5).
  9. Secure the rear of the rail to the rear rack flange with an M5 screw (see Figure 5).
  10. Repeat the steps to secure the opposite rail to the rack cabinet.
