Complete the following steps to install the support rails:
Note: Refer to Figure 14 while performing these steps.
1. Ensure that the rack cabinet has already been installed.
2. Ensure that a stabilizer has been correctly attached to the bottom front of the
rack cabinet to prevent the rack cabinet from tipping forward while the DS4800
is being installed.
Refer to the installation and service guide, or equivalent, for the rack cabinet
as required.
3. If you have not yet done so, remove the mounting rails, mounting hardware,
and line jumper cords from the DS4800 shipping box, which is on the bottom
of the shipping box beneath the DS4800 chassis. Do not remove the DS4800
from the shipping box at this time.
Attention: The mounting rails, mounting hardware, and line jumper cords
may be packed beneath the DS4800 in the shipping box. To remove these
items from the shipping box without first removing the DS4800, open the two
long sides of the shipping box. Then open and fold flat the two short sides of
the shipping box. This enables you to access the mounting rails, mounting
hardware, and line jumper cords without first removing the DS4800 from the
shipping box.
4. Locate the two support rails and six of the eight M5 screws that are supplied
with the DS4800.
5. The rack-mounted unit is four EIA units high. Decide accordingly where you
are going to install the support rails.
Attention: Use the rack mounting templates in this chapter or in Appendix C,
"Rack mounting templates," on page 181 to locate the proper rack mounting
holes for installing the support rails into the rack cabinet.
Note the following considerations before you choose where to install the rails:
v Plan the installation so that each DS4800 subsystem and its associated
storage expansion enclosures are mounted together in the same rack, or in
adjacent racks if necessary.
