Errors & Troubleshooting
If the library is a single level or only one power supply is not powering
on, use the following to troubleshoot the issue:
• If the power supply fan does not move - even slightly - when the
standby switch is moved to the
ON position:
1. Replace the power supply.
2. If this does not resolve the problem, replace the standby switch
assembly.
3. If this does not resolve the problem, replace the mother board.
• If the power supply fan moves slightly, and then stops, the power
supply is detecting a condition causing it to shut down. The most
likely condition is a short within that level of the library:
1. Remove all cards and drive modules from that level.
2. At the lowest level or on a single-level library, disconnect the
umbilical cable going from the mother board to the translate
frame assembly.
3. If the power supply fan now spins when powered up, begin adding
the cards, drive modules, and umbilical cable back into that level
until a component prevents the power supply from coming up.
4. Replace the suspected component.
5. If after removing cards, drive modules, and the umbilical cable,
the power supply still does not power up, then detach the front
panel cable at the mother board, the solenoid/sensor cable
assemblies on the power supply side and the interconnect cable(s)
in a multi-level library.
6. If the power supply still does not power up, disconnect the solenoid
on the non-power supply side at the mid-cable connector. Do not
disconnect the cable assembly from the mother board as this will
also disconnect the power switch. If this resolves the problem,
replace that solenoid assembly.
7. If the power supply still does not power up, replace the mother
board. Otherwise, reattach the cables until the one which causes
the failure is found, and replace that cable.
