Installing the 5886 on the rail assembly

You might need to install the system on the rail assembly. Use the steps detailed in this procedure to
perform this task. In addition to related safety information, illustrations of the related hardware
components are provided.
Before installing the system on the rail assembly, ensure that the stabilizers are extended and the tip plate
is attached to the bottom front of the rack to prevent the rack from falling forward when the rails are
pulled out of the rack. Refer to "Rack safety notices" on page 106.
To install the system unit on the rail assembly, follow these steps:
1. (Optional) To reduce the weight of the unit for easier installation in the rack cabinet, remove the
power supplies. To remove a power supply, complete the following steps:
a. On the left side of a power supply, press the orange release tab to the right just enough to release
the handle [no more than 6.4 mm (0.24 in.)] as you rotate the handle downward.
Figure 71. Removing power supplies
b. Carefully slide the power supply out of the unit.
c. Repeat this step for the other power supply; then, set both units aside for later installation.
2. (Optional) To reduce the weight of the unit for easier installation in the rack cabinet, remove the hard
disk drives. To remove a hard disk drive, press the latch and pull out the handle; then, carefully pull
the drive from the unit. Repeat this step for all hard disk drives.
Note:
a. Before you remove any hard disk drives, make sure that you mark their locations so that you can
reinstall them in the same locations.
b. Handle hard disk drives gently and do not stack them. Follow all precautions for static-sensitive
devices.
