Each Option 11C Mini chassis measures 8.4 in. (213 mm) high by 17.2 in. (437 mm) wide by 12.8 in. (325 mm) deep.

Equipment layout plan for installing the chassis on a wall horizontally and vertically

Figure 9 on page 71 shows a typical wall layout, using BIX cross-connect equipment, for installing the chassis on a wall in a horizontal position. Figure 10 on page 72 shows a typical wall layout, using BIX cross-connect equipment, for installing the chassis on a wall in a vertical position. Use of other types of terminal blocks and equipment can change the layout. As a result, if required, adjust the height at which you place the chassis in relation to other equipment. If required, also adjust the distances between the power outlets and the backboard.

Use the following guidelines to position the system equipment on a wall.

It is recommended that you fasten a 3/4 in. (20 mm) plywood (or other material like plywood) backboard to the surface of the wall. Fasten the Option 11C Mini equipment to this backboard.

When planning for a system with DTI/PRI capability, allow space on the backboard for the channel service unit (CSU).

Leave at least 6 in. (155 mm) above the mounting bracket and any obstruction (such as a pipe or conduit) so that there is room to lift the chassis on and off the bracket.

Leave at least 12 in. (305 mm) between the top of a chassis and the ceiling to make sure that there is enough ventilation for the system.

Leave 10 in. (255 mm) between the bottom of the lower chassis and the floor to prevent water damage.

If you use the NTAK92 Off-premises protection module, allow for correct installation (according to local practices).

Make sure power outlets are within reach of each system chassis. See Table 5 on page 37 for cable and wire specifications.
