Swapping power supplies
Procedure
1. Unplug the power cord from the power source then from the replacement library enclosure if this
action was not done previously. See “Installing your drive in the replacement library enclosure” on
page 238.
2. Swap the power supply in the defective library with the power supply in the replacement library
enclosure.
a. Remove the power supply from the defective library and from the replacement library enclosure.
To remove a power supply from a library:
1) Loosen the three blue captive thumbscrews on the power supply.
2) Pull on two of the thumbscrews, on opposite sides of the power supply, and pull the unit
away from the rear panel of the library.
3) Grasp the top and bottom edges of the power supply and remove it from the library.
b. Install the power supply that is removed from the replacement library enclosure in the defective
library to return to IBM. To install a power supply:
1) While the power supply is supported, align the power supply with the groove in the enclosure
rails.
2) Push the power supply forward until it is properly seated.
3) Tighten the thumbscrews.
3. Plug the power cord into the replacement library enclosure, then into a power source.
4. Power ON the replacement library enclosure.
a. If power ON is successful:
1) The replacement library enclosure powers up with the Ready/Activity LED (▌1▐ in Figure 186
on page 243) ON.
2) Power OFF the replacement library enclosure.
3) Unplug the power cord from the power source, then from the library.
4) Proceed to “Swapping library controller cards” on page 241.
