13-3-1-4. Rear Fan of Power Supply Unit
The air flow direction of the left rear fan of the power supply unit differs from that of the right rear
fan as follows.
• Right fan Exhaust direction
• Left fan Suction direction
For the POWER SUPPLY ASSY L (ST) (40098974) and POWER SUPPLY ASSY R (ST)
(40098950) used for the ST specification, remove the screws (SL4033591SC) shown below and
changing the air flow direction of the fan enables to swap the left fan with the right fan, and vice
versa. (For the fan for the EN specification, the fan mounting position cannot be changed since
different parts are used.)
