Disconnect the power supplies from the power supply backplane connectors by
removing both power supplies at least part way out of the chassis. See
.

Move the air divider.
The air divider that separates the disk drive backplane area from the rest of the chassis (and
includes the system Fault Remind button mechanism) must be moved to allow access to the
power supply backplane board and allow removal of the motherboard. The air divider is
mounted to the power supply side wall using two tabs which are inserted into slots in the side
wall. For this procedure, you can leave the cables attached to the air divider.
Caution -
Hardware damage. Try not to allow the SAS cables to rub against the CPU0 heatsink
radiator fins. They are sharp and can damage the cable insulation.
a.
Lift the air divider so the tabs clear the slots in the power supply side wall.
b.
Move the air divider away from the side wall and gently rotate the divider
and the cables attached to it away from the backplane area and set it in the
empty memory riser area.
9.
Disconnect the disk drive backplane power and data cables from the disk drive
backplane.
