the Service Action Allowed status LED of the failed power supply and fan
unit is not lit when both RAID controllers are optimal, contact your IBM
support representative.
Attention:
Electrostatic discharge can damage sensitive components.
Touching the storage subsystem or its components without using a proper
ground might damage the equipment. To avoid damage, use proper antistatic
protection while handling any components.
6. Put on antistatic protection.
7. Unpack the new power supply and fan unit.
Save all packing materials in the event you need to return the new power
supply and fan unit.
8. Apply the appropriate label to the LED column for the replacement power
supply and fan unit. The labels and instructions are included with the
replacement power supply and fan unit. Make sure that the labels are aligned
properly and do not cover any LEDs.
9. Unlatch the top and bottom levers on the failed power supply and fan unit.
Rotate both levers out simultaneously and remove the failed power supply and
fan unit. (Figure 117 shows a power supply and fan unit sliding from the
storage subsystem chassis.)
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
DS5100 and DS5300 enclosure so that the power supply and fan unit is
pulled evenly into the DS5100 and DS5300 chassis, ensuring full electrical
connection contact on all interface pins.
