Technical Manual 11
If the speaker panel needs to be removed, a mir-
ror programming port connector is provided on
both backplanes.
Programming for Series I 800MHz units is done
via EPROM and is detailed in section 6.1. The
RJ11 front port is covered (not used).

3.1.1.5 Dual Power Supply module
The Dual Power Supply module is made up of
two separate power supply units coupled in a
single chassis.
Refer to Table 1 on page 7 for tabular listing of
power supply LEDs indicators.
Refer to Figure 1 for the front panel LED lay-
out.
This module has:
•
Two “Power” red-colored pushbutton
switches - Push in for ON and release out
for OFF. Control complete power distribu-
tion to the Radio assembly
•
Two “ON” LEDs - light green when push
button(s) is (are) ON; DC power is distrib-
uted to radio modules. Flash green in con-
junction with the “OL” LED (flashing red)
when an over voltage condition is present.
•
Two “Stby”- Standby voltage LED, lights
red when push button is off; AC power is
applied but DC is not distributed to radio
modules. To remove presence of voltage,
disconnect both power cords.
•
Two “OL” LEDs - Monitor current over-
load, light steady red when supply exceeds
current limit set; nominally 25Amps (T808
model). Flashes red in conjunction with the
ON LED (flashing green) when an over
voltage condition is present.
3.1.1.5.1 Rear Connections
Referring to Figure 10, (convection-cooled
model shown; fan-cooled model not illustrated),
the rear connections for each of the power sup-
ply are:
Fail Alarm –
Off: Power supply OK; approx. +Vout
(via 1k resistor - typ. 13.8V).
ON: Power supply failure; approx. -
Vout (via 11k resistors - typ. 0V)
+ Remote – Not used for Paragon
- Sense – Not used for Paragon
-VE – main ground (0V)
+13.8V – Mains DC output supply

3.1.2.1 Backplane PCB
Referring to Figure 3, two main backplanes are
used. Their main components are:
