7.4.6 Disassembly Procedure
Disconnect mains power to the source and wait 10 minutes to allow the capacitors to
discharge before attempting to disassemble the unit. Remove the top cover, unplug P7 from
the current limit board, and unplug the fan from the AC logic board connector. Then carefully
unplug the AC logic board from the AC and the DC power boards. The AC logic board can then
be lifted from the unit.
Using a 5/16 inch socket driver remove the four bolts that hold the AC power module heatsink.
There is one bolt at each corner. Carefully remove all the hardware from the unit. The AC power
module can now be unplugged from the input/output board and removed from the unit.
The DC - DC module can be unplugged by first removing the two nuts holding the clamp that
secures the heatsink to the chassis. See Figure 6-1. Care must be taken in unplugging the two
connectors P4 and J12.
To reassemble, reverse the above procedure, taking care to ensure J12 on the DC-DC board
and J8 on the AC board are properly mated. This may entail supporting the connector from
behind with a screwdriver.
