Frame Fan Jumper Settings
There is a jumper on a small circuit board (064851) in the fan assembly at the top
of the Signal Processor Frame in each Model 4000 Switcher. This jumper must be
in the correct position for proper operation of these power supplies.
If your switcher has been shipped directly from the factory, this jumper setting will
be correct. If you are changing types of power supplies, make sure this jumper is
set correctly.
To check the jumper setting, do the following:
CAUTION
Make sure power to the frame is OFF.
1.
Loosen the retaining screws of the fan assembly and pull the assembly out of
the rack.
2.
Check the position of the BYPASS/PROTECT jumper.
a.
For the Todd +5 Volt power supplies, set the jumper to the BYPASS
position. The Todd supplies have internal protection. They will not operate
with the jumper in PROTECT mode.
b. For the Pioneer +5 Volt power supplies, set the jumper to the PROTECT
position. The jumper, in PROTECT position, is intended to prevent a
harmful surge should the P5 V supply be accidentally shorted.
Primary Frame Power Supply Installation
To install the Signal Processor Primary Frame Power Supply in the equipment
rack, refer to
1.
Ensure that the Primary Power Supply is disconnected from any power
source.
2.
Locate the installation kit containing the power supply assembly slide mounts
and hardware. The installation kit consists of the following:
a.
Slide Mounts
b. Mounting Hardware
3.
Measure the location of the slide sections mounted on the power supply
chassis to determine the height at which the stationary sections of the slides are
to be mounted in the rack.
NOTE:
The Primary Power Supply will be attached to the bottom of the Signal Processor
Frame by eight captive screws. It must be installed so that it is touching the bottom of the
Frame.
4.
Verify that the screws holding the chassis sections of the slides to the power
supply chassis are securely tightened.
