Installing the DS4800 on the support rails

This section provides instructions on how to install the DS4800 in a rack cabinet.
Attention:
and model number, and MAC addresses for your DS4800 Storage Subsystem in
Appendix B, "Records," on page 179, as described in step 7.
Use the following procedure to install the DS4800 Storage Subsystem on support
rails in a rack cabinet. To mount a storage subsystem in the rack cabinet, all
support rails must be installed in their correct locations. If you need to install the
rails, see "Installing the support rails" on page 32.
CAUTION:
Never install components or other equipment in the top half of a rackmount
cabinet while the bottom half is empty. Doing so can cause the cabinet to
become top-heavy and to tip over. Always install hardware in the lowest
available position in the cabinet.
Before installing the storage subsystem in the cabinet, ensure that there are no
obstructions, either in the cabinet or outside the cabinet, that would make ready
removal and replacement of any of the components impossible. Check for
obstructions at the front and rear of the cabinet.

MAC addresses are located near the Ethernet ports on each RAID controller, as
shown in Figure 100 on page 179. You may not be able to easily access this
information after you install the DS4800.
