Dell TL2000 manual Isolating Drive Sled Problems

4.For power supplies with LED’s, if the “Amber” LED is lit, replace the power supply (refer to “Replacing a Power Supply” on page 10-7).

5.If your power supply has no LED’s, and you have verified that the electrical outlet works properly, but the power supply is still failing, replace it (refer to “Replacing a Power Supply” on page 10-7).

6.If the power supply seems to be delivering power to the library (Operator Control Panel and front panel LED’s may be functioning); however, air does not flow from the power supply cooling fan grill on the rear of the library, replace the power supply (refer to “Replacing a Power Supply” on page 10-7).

7.If the power supply seems to be delivering power to the library (Operator Control Panel and front panel LED’s may be functioning), and air is flowing from the power supply cooling fan grill on the rear of the library, observe the “Green” LED (lowest of the three). If it is lit, the power supply is OK.

Note: If your library has -04 level redundant power supplies (see label on top of power supply), it is normal for the one in “Standby” mode to turn its “Green” LED off. You can test this power supply by pulling the power connector from the other “Active” power supply. The power supply that was in “Standby” mode will now become “Active”, and its “Green” LED should light. If it doesn’t, replace it (refer to “Replacing a Power Supply” on page 10-7).

If your library has -05 level redundant power supplies, the ″Green″ LED will be ON on both power supplies. If both ″Green″ LEDs are not ON, replace the failed power supply (refer to “Replacing a Power Supply” on page 10-7).

8.If the “Green” LED is not lit, and it is the only one in the Library, replace it (refer to “Replacing a Power Supply” on page 10-7).

Isolating Drive Sled Problems

Prior to replacing a drive sled CRU, verify that the following activities have been performed:

1.Ensure that the drive firmware is at the latest level. To determine current library and drive firmware levels using the Operator Control Panel:

v Library firmware: Monitor → Library → Identity → Version

v Drive firmware: Monitor → Drives → Identity (select a drive) → Firmware Rev

2.Prior to powering OFF the library, if possible, collect a drive dump and save it on the host console for possible future use by Technical Support. Drive dumps can also be saved using the Web User Interface. See chapter 4, Operations, for instructions on using the “Save Drive Dump” on page 5-52option under the Service Library menu selection.

3.Try reseating the drive sled.

Note: The drive sled is hot-pluggable so it is not necessary to power off the library. See “Replacing a Tape Drive Sled” on page 10-3.

4.Cycle power to the library.

5.If air does not flow from the drive sled cooling fan grill on the rear of the library, replace the drive sled CRU. Several library error codes also point to cooling problems. See “Replacing a Tape Drive Sled” on page 10-3.

6.If the drive is experiencing permanent or temporary errors or if the amber Clean LED is lit on the front panel of the library, select Clean Drive from the
