This process applies to the SL48 only. A redundant power supply can be replaced without powering off the Library.
In this process you will:
• Power off the Library, if necessary, and unplug the power cord. (Only Libraries with a single power supply.)
• Remove the old power supply.
• Install the new power supply.
• Verify the replacement.

CAUTION:
Parts can be damaged by electrostatic discharge. Keep parts in electrostatic containers until needed. Ensure that you are properly grounded when touching static‐sensitive components.

To replace a power supply:
1. If the Library only has one power supply, power off the Library from the front panel, if possible, and
    remove the AC power cord. Otherwise, just remove the AC power cord from the power supply to be
    replaced.
2. Loosen the three captive thumbscrews on the power supply. Grasp a thumbscrew stem on each side of
    the power supply and while supporting the bottom, pull the power supply out of the Library, as shown in
    Figure 107).
3. Position the new power supply on the alignment rails and slide it into the Library until it is flush with the
    back panel, as shown in Figure 108. Tighten the three blue thumbscrews to secure the power supply.
4. Attach an AC power cord to the replaced power supply and plug into a power outlet. Power on the
    Tape Library, if necessary.
5. Verify that the new power supply is operating properly.

Power supply LEDs
1. Blue AC power is connected.

3. Green The power supply is producing good power for the Library.

Use the packaging from the replacement power supply to return the failed power supply to Oracle.
