Removal and installation procedures
Power supply
NOTE. It is not n
ecessary to remove the installed hard disk drives from the chassis
drive tray before removing the power supply. The power supply screws can be
accessed through the access holes in the drive tray. Howeve r, it might be easier
to disconnect the two-pin cable from the power supply to the conversion board
with the drive tray removed.
Follow these steps to rem ove the power supply assembly:
1. Remove the six T15 scre ws securing the power supply access cover from
the end of the Power Supply.
2. Remove the two T15 screws securing the right side of the power supply
support bracket.
3. Remove the power supply support bracket.
4. Disconnect the line trigger cable from J7 of the Power conversion board.
5. Disconnect the
power supply cable from the line filter cable.
6. Remove the two T15 screws s ecuring the power supply shield tabs to the
top front chas
sis.
7. Pull the power supply assembly from the left side of the chassis. This will
take a little
effort to pull, as the power supply must disconnect from the power
convertor board.
CAUTION. To prevent damage to the power convertor board connector, do not lift
the left end of the power supply while pulling.
