Installing the 51x, 710, or 9110-51A into a rack

You might need to install the system into a rack. Use the procedure in this section to perform this task.

Use this procedure if you are installing the system into an existing rack. If the rack is not installed, go to the instructions for installing the rack, and then return to this procedure for instructions on installing the system unit into the rack.

To install the system into a rack, complete following procedure:

1. Read the Rack Safety Notices. Failure to read these notices could cause damage to the equipment or injury to the installer.
2. Complete a parts inventory (See Complete a parts inventory).
3. Locate the rack-mounting template, the rack-mounting hardware kit, and the system rail assemblies that were included with your system unit.

   The system rails are front-to-back and left-to-right side dependent. The rails are labeled "left" and "right" to indicate their placement when you face the front of the rack. There two large latch assemblies at the back of each rail. These latch assemblies go in the back of the rack.

4. Determine where you will locate the expansion unit in the rack. See Determining location.
5. Mark the location. See Mark the location using rack-mounting template. If you do not have the rack-mounting template, see Mark the location without a rack-mounting template.
