Installing the Server In a Rack

This section describes how to install the server in a rack.

Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

Statement 1006

To install the slide rails and the server into a rack, follow these steps:

Step 1 Install the slide rails into the rack (see Figure 2-2):

a.Align the slide-rail assembly inside the rack posts with the length-adjustment bracket (Figure 2-2, item 4) toward the rear of the rack.

b.Compress the length-adjustment bracket until the mounting pegs (item 5) and locking clips (item 6) on the slide-rail assembly engage the desired rack holes on the front and rear rack posts:

–The mounting pegs fit square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), or #12-24 UNC threaded holes. They fit the shape of the hole when the pegs are compressed.

–The smaller #10-32 round mounting pegs are enclosed in the center of the compressible rear pegs. However, to use the #10-32 pegs, you must use a flat-bladed screwdriver to remove the square or round front pegs.
