10. Install the new power supply-fan.
a. Carefully position the power supply-fan in the storage subsystem chassis.
The power supply-fan has a relief formed along one long edge of the
component. The component relief fits onto a rail cast into the storage
subsystem chassis. Ensure that the component relief fits onto the rail
before attempting to slide the controller into the storage subsystem
chassis.
b. With the left and right levers rotated out perpendicular to the face of the
power supply-fan, slide the back of the power supply-fan into the
appropriate slot.
c. Holding both levers, slowly push the power supply-fan until the notches in
both the left and right levers are aligned with the pins on the DS4800
enclosure so that the power supply-fan is pulled evenly into the DS4800
storage subsystem chassis, ensuring full electrical connection contact on all
interface pins.
Attention: Verify that the power supply-fan does not snag any other
DS4800 cables when you slide it into the bay.
d. Press the power supply-fan fully into the slot, engaging the pins on the
enclosure.
e. Hold open both latches and push both left and right levers simultaneously
to the closed position. Release the latches. When you release the latches,
you should hear both latches snap over the levers, indicating that the
power supply-fan is locked in place.
11.
Wait up to 5 minutes for the DS4000 Storage Manager client software to
recognize the new power supply-fan.
12. Complete any remaining Recovery Guru procedures for power supply-fan
replacement, if needed.
13. Did this correct the problem?
v Yes ā Go to step 14 on page 148.
v No ā Verify the following:
ā Both power supply-fan switches on the back of the DS4800 are turned
on.
ā The circuit breaker for the electrical outlet that DS4800 connects to has
not been tripped.
