2. Remove the front rack door, and if necessary, remove the rear rack door. For 7014 Model T00 and T42

3. If you do not have a rack-mounting template, go to step 4. Using the rack-mounting template,
determine where in the rack to place the system. Make note of the Electronics Industries Association
(EIA) location number.
Note: The rack-mounting template has printed illustrations located on the front of the template. Each
illustration is designed to aid in identifying the EIA location holes used when planning to
populate your rack. Do not use the rack-mounting template without reading and understanding
the following substeps. Each step must be completed in its entirety.
Attention: Mounting the rails is a complex procedure. To install the rack rails correctly, you must
read, and then perform each procedure step in the order given. Failure to perform each step in the
order given may cause rail failure.
4. Note the following when using the rack-mounting template:
v Each black or white unit on the template is equal to 1 EIA unit.
v Each EIA unit consists of three holes.
v The EIA units illustrated on the template must be aligned with an EIA unit located on the rack.
v It is not necessary to align like-colored EIA units. For example, a black EIA unit illustrated on the
rack-mounting template does not have to be aligned with a black EIA unit located on the rack. A
black EIA unit on the rack-mounting template can be aligned with a white EIA unit located on the
rack. See the following illustration.
