Servicing Frame Power Supplies
5.
At the top of the circuit board containing the indicator LEDs, reconnect the
multiwire connector that you previously disconnected.
6.
Reconnect the two plugs to the jacks at the top of the compartment.
If this is the upper power supply in a redundant system, connect the
corresponding plugs in the lower supply to their mates in the bottom of this
supply.
7.
Turn on the power supply.
8.
Adjust the voltages, as in the Primary and Redundant Power Supply Voltage
Adjustments procedure in Section 2 of this manual.
9.
Reinstall the left and right rear access panels of the power supply.
10. If this is a redundant power system:
a.
You must first replace the Multi-Output power assembly in the second
Power Supply frame (if it is not a Todd supply) by repeating the procedure
given above.
b. When you have completed the installation (of both Multi-Output supplies,
if required), reconnect the power source and apply power to both units.
c.
Before you install the rear plates on the Power Supply frames, you must
adjust the output voltages for load-sharing. Refer to the Primary and
Redundant Power Supply Voltage Adjustments procedure in Section 2 of
this manual.
Replacement of +5 Volt Power Supply Assembly
The following procedure describes replacing a P5 Volt power supply
assembly with a Todd power supply assembly.
For any of the other three possible replacements—replacing a Pioneer unit with a
Pioneer, replacing a Todd unit with a Todd, or replacing a Todd unit with a
Pioneer—use the following procedure as a guide and perform the appropriate
steps.
Removal of P5 Volt Supply
To replace a P5 Volt assembly with a Todd Multi-Output assembly,
proceed as follows:
1.
On the front panel of the main Signal Processor Frame Power Supply, turn off
the main power switch. The indicator LEDs on the front panel will go out.
If there is a Redundant Signal Processor Frame Power Supply, also turn off its
main power switch.
2.
Inside the switcher Control Panel, turn off the main Control Panel Power
Supply switch and (if present) the redundant Control Panel Power Supply
switch.
