Replacing the power supply (SL48)
This process applies to the SL48 only. A redundant power supply can be replaced without powering
down the Library.
In this process you will:
• Power off the Library 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 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 101).
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 102. 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.

OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
