Equipment layout plan
Develop an equipment layout plan to determine where each system
component will be positioned before installing the Option 11C Compact
system.
Preparation of the site according to the plan is important. 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.
Consideration should be given to the lengths of the various cables in order to
make the best use of space available. Refer to
Table 2, “Cable and wire
specifications,” on page 16 for a complete description of Option 11C
Compact system cable and wire specifications.
General layout guidelines
Use the following guidelines to assist in positioning the system equipment:
• The cabinets are designed to be mounted on a wall.
• Each cabinet measures approximately 20 in. (510 mm) high by 15 in.
(380 mm) wide by 12 in. (305 mm) deep.
• If only installing a main cabinet, leave adequate space for an expansion
cabinets.
Note: The interconnecting fiber optic cable measures approximately
33 ft (10 m). The distance between the main and expansion cabinets is
therefore limited by the length of the interconnecting fiber optic cable.
• When planning for a system that is equipped with DTI/PRI capability,
allow space on the backboard for the channel service unit (CSU).
CAUTION
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.
