FIGURE 4-ll-PERCEPTION,
EXPANSION CABINET INSTALLATION
NOTE:
Prior to routing intercabinet cabling, check the
15amp fuse (F2) located at the top of the main
power supply to verify that it is in working
order.
11) Route the power supply cabling through the
hole in the expansion cabinet and connect
both power supplies to the lower connectors
at the Pl , P2 and P3 receptacles.
12) With the main power supply turned OFF, plug
the AC power cord into the AC outlet.
13) Momentarily press each secondary power
supply circuit breaker to verify that it is not
tripped.
14) Place the main power supply power switch in
the ON position.
15) Verify that all secondary power supply power
indicator LEDs are on. If any of the LEDs are
not on, replace the NPSA-S (RINGER LED
should be pulsating rapidly).
16) Using a multimeter (set to the appropriate
ranges), check the pins on connectors 5701
and 5702 on the secondary power supply for
the voltages shown in Figure 4-9. (The con-
nectors are on the rear of the power supply
chassis.) Measure between the voltage pin
and a ground pin. (All ground leads are tied to
a single point, so any can be used.) Figure 4-
9 also shows the acceptable range for each
output voltage. If a measured voltage falls
outside of the acceptable range, replace the
secondary power supply.
17) Turn the power supply OFF.
18) Plug in connectors J701 and J702.
19) Route cable J703 into the basic cabinet and
plug it into connector 5703.
20) Reinstall the rear panels and doors on both
cabinets and secure in place with screws.
