Isolating Drive Sled Problems - Dell PowerVault TL2000 User Manual

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 10-10).
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 10-10).
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 10-10).
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 10-10).
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 10-10).

Isolating Drive Sled Problems

Prior to replacing a drive sled CRU, verify that the following activities have been
performed:
1. BEFORE POWERING OFF THE LIBRARY, write the drive dump to flash. It is
important to preserve the drive dump on the drive for analysis by Technical
Support.
Note: If you are instructed by Dell Technical Support to copy the drive dump
to your host computer, use one of the following methods:
v Web User Interface: Refer to "Service Library: Save Drive Dump" on
page 5-60.
v ITDT: Refer to "Using the ITDT Firmware Update, Dump Retrieval
and Drive Test Tool " on page 9-4.
2. Ensure that the drive firmware is at the latest level. To determine current
library and drive firmware version using the Operator Control Panel:
v Library firmware: Monitor → Library → Identity
v Drive firmware: Monitor → Drives → Identity (select a drive) Drive firmware
is identified in the FW Rev field.
3. Try reseating the drive sled.
Note: The drive sled is hot-pluggable so it is not necessary to power off the
library. See "Removing/Installing/Adding a Tape Drive Sled" on page
10-3.
4. Cycle power to the library.
