screws on the metal beam near UPS battery cavity as indicated in the picture below and
1 screw on the front wall in the PB system as indicated in the picture below and also in
the picture at end of last section. (Just as a reminder: To reassemble the HDD bracket,
the correspondent part of HDD bracket must be well inserted into the HDD bracket
holding slit on the rear wall of PB system before screwing it onto the metal beam.)
Both FDD and HDD can be removed from their bracket after removing the
respective power cable and data cable and removing the 4 screws holding the drive on
the bracket. Please always remember to check the cable orientation of pin 1 in
reconnection.
UM-7700 BOARD
To add the UM-7700 power management kit please note the area in the main
board exposed from HDD removal that there are a shorter 2 row male connector (JP15)
and a longer 2 row female connector (JP14) as marked in the picture ready for
accepting the adaptor board UM7700. However, please first change JP11 of main
board to pin 2-3 short from pin 1-2 short if the UPS status software detect function of
this adaptor board is to be utilized.
Please remove the 3 jumpers on JP15 on main board before carefully setting the
2 connectors on solder side of UM7700 to JP14 and JP15 on the main board. Reserve
the 3 jumpers so that once UM7700 shall be removed in the future they have to be
inserted back to the 3 horizontal pairs of pins nearest to the LPT connector on main
board in JP15 to keep proper function of main board. Route the cable from UM7700 to
allow the UPS battery connector to go into the UPS battery compartment.
