Installing the model 5802 or 5877 into a rack

You might need to install the expansion unit into a rack. This section includes procedures so that you can
perform these tasks.
This procedure assumes that you are installing the expansion unit into an existing rack. If the rack is not
installed, follow the instructions in Chapter 2, "Installing the rack," on page 3, and then return to this
procedure for instructions on installing the expansion unit into the rack.
For instructions related to installing, removing, and replacing a disk drive, disk-drive backplane, or
enclosure, see Disk drives.
To install the expansion unit into a rack, perform the following steps:
Attention: Installing the rails in the rack is a complex procedure. To install the rails correctly, you must
perform each task in order. Failure to do so might cause rail failure and potential danger to yourself and
the expansion unit. Also, note that for the 5802 and 5877, three people are required to safely lift the
system. Using fewer than three people to lift the system can result in injury.
