Attention:
Both support rails are shipped with three screws and spacers,
called alignment pins, already installed at the front of each rail. They have
been inserted in the front of each support rail as guides to indicate where not
to use M6 screws when you attach the front of the support rail to the rack. See
Figure 9.

Depending on which type of rack mounting flange is present on your rack, you
might have to remove some or all of the spacers. For example, if the rack in
which you are installing the support rails has round holes, you will need to
remove the spacers from the top and bottom alignment pins so that the rail sits
flush with the rack. See Table 9.

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 7 on page 17
and Figure 8 on page 18 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 FAStT100 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 FAStT100 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.
