Log snapshot shows the following Device warnings for a specific power supply.

Example below:

2017-11-29T08:50:44.672, 2.0.0.1.4, root, default, queryLibrary, 8450102, trace, 3816, "Device status warning", status=warn device=powerSupply

2017-11-29T08:50:44.776, 2.0.0.1.4, root, default, queryLibrary, 8450102, trace, 3816, "Device status warning", status=warn device=powerSupply

2017-11-29T08:53:21.126, 2.0.0.1.4, root, default, queryTable, 8458302, trace, 3816, "Device status warning", status=warn device=powerSupply

Cause

 The Library Controller has detected an issue with the functionality of the power supply. ie: bad fan.

Solution

Replace the power supply per the following instructions.

48 Volt Power Supply Module (Customer Interface): Removal
Note – You can hot-swap a 48V Power Supply Module, located in the Customer Interface Assembly, if a redundant power supply is present. Otherwise, the library must be offline.
1. Remove the center façade (for a two piece, see “Removing the Two-Piece Façade” on page 42 or for a one piece, see “Removing the Single Piece Façade” on page 45).
2. If a redundant power supply is not present, request the operator to place library offline to Host/ACSLS.
3. Press and hold the handle retention tab, then pull the handle.
4. Pull the power supply, by the handle, completely out of the slot.

48 Volt Power Supply Module (Customer Interface):   Replacement
1. Put the power supply handle in the extended position.
2. Push the replacement power supply, with the handle extended, fully into the slot until the connectors are seated.

3. Close the handle to secure the assembly.
4. Verify that the green LED lights.

48V Power Supply Module (Drive & Electronics Module): Removal

1. Open the library rear doors.
2. Note the ratio of functional power supply modules to the number of installed, operating tape drives; or, to the number of rail communication modules.
• You can hot-swap a 48V Power Supply Module if there is adequate redundancy.
• There must be a minimum of one functional power supply module per eight installed, operating tape drives after removing a power supply module.
• There must be a minimum of one functional power supply module per two installed, operating rail communication modules after removing a power supply module.
• Power supply modules are numbered from the bottom, up:
PS1 - 4, 7 - 10, 13 - 16, 19 - 22 power the drive bus.
PS5 - 6, 11 - 12, 17 - 18, 23 - 24 power the rail bus.

3. Power-off selected tape drives or rail communication modules until an adequate ratio can be maintained.
4. Press and hold the handle retention tab , then pull the handle to unseat the connectors.

48V Power Supply Module (Drive & Electronics Module): Replacement
Note – Be sure the power supply handle is in the extended position.If otherwise, a closed handle will prevent connector seating.
1. Push the replacement power supply, with the handle (2) shown in FIGURE 1-31 on page 51 extended, fully into the slot until the connectors are seated.
2. Close the handle to secure the assembly.
3. Verify that the green LED lights.
4. Close the handle to secure the assembly.
5. Verify that the green LED is ON.
6. Perform “48V Power Supply Module, Drive & Electronics Module Verification”
7. Power-up all tape drives that were powered-off during removal steps.
8. Close the library rear doors.
