DESCRIPTION
fully loaded DVIU cabinet requires two (2) Power
Distribution Panels.
Power Distribution Panel 19D904180G5 is used in the
Digital Voice Interface Unit (DVIU) cabinet to provide dc
power interconnections between the Redundant Power
Supply (RPS) unit and the DVIUs within the cabinet. A
Each panel distributes the +5 and ±12 Vdc power from
the RPS unit to the eight (8) DVIUs directly above it. Panel
1 serves DVIUs 1 - 8 and Panel 2 serves DVIUs 9 - 16.

LBI-39045
The panels mount on the cabinet's rear mounting rails.
See the Application Assembly Diagram in LBI-39041 for
additional rack-up details.
PIN-TO-PIN WIRING
AND COLOR CODING
POWER DISTRIBUTION
Table 1 identifies the pin-to-pin wiring pattern and the
wire color coding scheme used within the Power
Distribution Panel. This same color coding scheme is
followed in all power interconnecting cables within the
DVIU cabinet.
As shown in Figure 1, dc power from the RPS unit
enters the Power Distribution Panel at connector J1 via
Power Cable 344A4677P60. From this point, the power is
distributed to the eight (8) DVIUs that the panel serves via
connectors J4 - J11 and Power Cables 344A4677P40.
If the DVIU cabinet is equipped with nine (9) or more
DVIUs, a second Power Distribution Panel (Panel 2) is
installed in the DVIU cabinet to serve the second group of
eight DVIUs. Power for this second panel is not applied
directly from the RPS unit. Instead, a power "jumper" cable
jumps the +5 and ±12 Vdc power lines from the first panel
to the second panel. Specifically, this is achieved via
connectors J2 at each panel and Power Cable
344A4677P52.
NOTE
The 5 Vdc remote voltage sense leads from the
RPS unit are not routed through the Power
Distribution Panels. These leads, within Cable
344A4677P60, terminate at J1 on the first Power
Distribution Panel (Panel 1). The +5V sense lead
(brown) terminates at J1 pin 4 and the -5V or
return sense lead (white) terminates at J1 pin 3.
