Z100-TYPE HARDWARE
ADJUNCT POWERING
Adjunct Powering From the Equipment Room
Adjunct power can be provided at any cross-connect field where 4-pair circuits (Z100A1) are
provided to the station wiring. Figure 2-69 shows the powering arrangement used at the
equipment room. As shown in Figure 2-69, the power adapter cord is routed behind the jack
panel in the slot formed by the adjacent supports and connected to the individual or bulk
power supply located above the cross-connect field.
Adjunct Powering From Satellite Locations
Adjunct powering from a satellite location is identical to the adjunct powering from the
equipment room (see Figure 2-69).
Adjunct Powering From Site Locations
Adjunct power can be provided from any of the adapters located in site closets. Adjunct
power is provided at the site locations when the 4-pair building wiring from the equipment
room or satellite location exceeds 250 feet (76.2 m) or when 3-pair station wiring is run from
the equipment room to a 356A adapter.
Figures 2-70 and 2-71 show the connections required for an 258A and 356A adapters,
respectively. The 400B2 adapter and D6AP power cord are used to provide power on the
fourth pair of the 4-pair station cable. The D6AP power cord is connected to an individual
power supply or a bulk power supply. The D6AP power cord is available in 7 foot (2.1 m), 14
foot (4.3 m), and 25 foot (7.6 m) lengths.
