4. The rack-mounted unit is three EIA units high. Decide accordingly where you
are going to install the support rails.
Attention:
Use the rack mounting template provided in Figure 15 on page 33
and Figure 16 on page 34 to locate the proper rack mounting holes for
installing the support rails into the rack.
Note the following considerations before you choose where to install the rails:
v
If you are installing the EXP810 into an empty rack, install it into the lowest
available position so that the rack does not become unstable.
v
If you are installing more than one EXP810 in the rack, start at the lowest
available position, and work upward.
v
If appropriate, allow for possible later installation of other units.
v
If necessary, remove the rack power distribution unit before you install the
support rails.
v
For procedures and more information, refer to the installation and service
guide, or equivalent, for the rack.
5. Using a #2 Phillips screwdriver, loosen the two screws on the left support rail
that hold the two parts of the rail together (
�5�
).
Note:
The support rails are not marked as Left or Right. However, each rail
can be correctly mounted on only one side of the rack cabinet. The rails
should be mounted with the alignment pins at the back of the rack.
Figure 17 on page 36 shows the installation of the left support rail.
6. Hold the back of the rail against the inside of the rack-mounting flange. Make
sure the rail mounting guide pins are in the correct holes. See Figure 16 on
page 34 for illustration.
7. Using the 5/16 (8 mm) hex nut driver, securely tighten the two M5 screws
(
�2�
).
Note:
Make sure you use a washer when installing an M5 screw through a
square
hole on the rack-mounting flange.
8. Extend the rail to the front of the rack until it makes contact with the front
rack-mounting flange (
�3�
).
9. Securely tighten the two M5 screws (
�1�
).
Note:
Be sure to install the screws labeled
install
first
in Figure 15 on page
33.
10. Securely tighten the two screws on the left support rail that hold the two parts
of the rail together (
�5�
).
11. Repeat step 5 through step 10 for the right support rail.
Note:
Because the mounting holes on the rack are not always the same size
as the mounting screws, the lip (
�6�
) of each of the support rails may
not line up evenly. Make minor adjustments as needed to ensure that
the lip of the left and right support rails are lined up evenly on the racks.
Failure to do so will cause the storage expansion enclosure to fit
unevenly in the rack.
