10. Install the new power supply and fan unit.
a. Carefully position the power supply and fan unit in the storage subsystem
chassis. The power supply and fan unit 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 and fan unit, slide the back of the power supply and fan unit
into the appropriate slot.
c. Holding both levers, slowly push the power supply and fan unit until the
notches in both the left and right levers are aligned with the pins on the
DS4800 enclosure so that the power supply and fan unit is pulled evenly
into the DS4800 storage subsystem chassis, ensuring full electrical
connection contact on all interface pins.
Attention: Verify that the power supply and fan unit does not snag any
other DS4800 cables when you slide it into the bay.
d. Press the power supply and fan unit 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 and fan unit is locked in place.
11.
Wait up to 5 minutes for the DS4000 Storage Manager client software to
recognize the new power supply and fan unit.
12. Complete any remaining Recovery Guru procedures for power supply and fan
unit replacement, if needed.
13. Did this correct the problem?
v Yes – Go to step 14 on page 156.
v No – Verify the following:
– Both power supply and fan unit switches on the back of the DS4800 are
turned on.
– The circuit breaker for the electrical outlet that DS4800 connects to has
not been tripped.
