For multi-cabinet systems the following guidelines apply for both horizontal
and vertical expansion:
• The maximum distance between the main cabinet and each expansion
cabinet is 1.8 mi (3 km).
• The minimum distance between cabinets when mounted above one
another (vertical expansion) should be 12 in. (305 mm).
• The minimum distance between cabinets when mounted next to each
other (horizontal expansion) is defined by an alignment bracket as shown
in Figure 15 on page 61. However, this is the minimum distance; the
cabinets can be positioned further apart to suit site requirements.
Note 1: The equipment layout plans shown in this chapter are
applicable to fiber-optic connected cabinets installed within close
proximity to each other (such as on the same wall). These layout
guidelines are not as stringent if the cabinets are located in separate
rooms, on different floors, or in different buildings.
Note 2: The examples given in the following pages for multi cabinet
systems, apply to three cabinets ( 1 Main, 2 Expansion) systems only.
However, up to four expansion cabinets or Mini chassis can be connected
to a Main Option 11C cabinet for a maximum configuration of five
cabinets.

The mounting location of either the NTAK75 or the NTAK76 backup-up unit
is governed by the location of the Option 11C cabinets and the length of the
NTAK0410 cable. The NTAK0410 cable is 6 ft (1830 mm) long.
Typical wall layouts using BIX cross-connection equipment are shown in
Figure 14 on page 60 and Figure 16 on page 63. Use of other types of terminal
blocks and equipment will alter the layout. As a result, you may need to adjust
the height at which you place the cabinets in relation to other equipment. You
may also need to adjust the distances the power outlets are from the
backboard on AC powered systems. The positions for the mounting brackets
are shown in Figure 15 on page 61.
