Before installing the Option 11C, you need to develop an equipment layout
plan to determine where each system component will be positioned.
Note: Examples shown in this chapter refer to three cabinet systems.
Consideration should be given to the lengths of the various cables in order to
make the best use of space available. Refer to "Cables and wires" on page 32
of this guide for a complete description of Option 11C cable and wire
specifications.
Preparation of the site according to the plan is critical. Site preparation
consists of making sure the site is ready to accept the equipment and that
items such as power outlets and backboards are correctly installed.
The mounting surface must be able to support at least 100 lb (45 kg). It
is recommended that you secure a backboard consisting of 3/4 in. (20
mm) plywood, or other similar material, to the surface of the wall to
hold the equipment.
Follow the guidelines below to assist you in positioning the system
equipment. If you plan on installing one or more expansion cabinets, you
should read the section called "Additional considerations for multiple-cabinet
systems" on page 58.
• The recommended method of system cabinet installation is
wall-mounting. If you cannot mount the cabinets on the wall (for
example, if there is not enough wall space), you can mount each cabinet
on an optional pedestal. However, you will still need wall space for
installing a cross-connect terminal and other optional equipment.
• Each Option 11C cabinet measures 25 in. (635 mm) high by 22 in.
(560 mm) wide by 12 in. (305 mm) deep, or 14 in. (356 mm) deep with
the newer Option 11C door.
