Installation of Todd +5 Volt Supply
1. To install the replacement supply, slide it into place and install the front
mounting screws.
2. Feed the small multi-wire cable from the new power supply through
the hole at the top left of the +5V supply compartment (see Figure 4-7),
and on through the frame to the hole into the Multi-Output supply
compartment. If necessary, gain access from the front of the frame.
3. In the Multi-Output supply compartment, connect the connector on the
end of the multiwire cable to the mating connector at the top of the
circuit board.
4. In the +5 Volt supply compartment, ensure that the connector on the
other end of the multiwire cable is securely attached to the mating
connector on the circuit board.
