TS3310 Tape Library Setup and Operator Guide
A drive sled fan is spinning too slow or not at all.
Regular polling/monitoring of the fan indicates a problem.
1. Hardware failure of fan.
2. Wiring or PCBA failure.
3. Blocked air paths.
4. Physical obstruction.
Drive Sled
Before performing the following:
1. "Removing a Drive Sled" on page 12-16
2. "Replacing a Drive Sled" on page 12-17
refer to "Diagnosing a Problem" on page 10-2 for
additional diagnostic procedures.
A power supply has detected loss of AC power. AC power
loss to a single power supply control module is unlikely to
be able to post this ticket due to the speed at which system
shut down occurs after an AC loss. This Ticket is most
likely to occur when there is AC loss to a redundant power
supply in a control module or any supply in any expansion
module.
AC power status from the supply creates an interrupt that
is managed by software.
1. AC supply is gone (cord removed, customer side AC
failure, etc.).
2. Individual on/off switch for the supply has been set to
off.
3. Hardware failure inside supply.
Power Supply
Perform the following:
v "DR009: AC Failure Diagnostic" on page 11-37
Before performing the following:
v "Removing a Primary Power Supply" on page 12-25
v "Reinstalling/Replacing a Power Supply" on page 12-25
refer to "Diagnosing a Problem" on page 10-2 for
additional diagnostic procedures.
Power supplies report four failure conditions that are
considered to be a hardware failure within the supply: Fan
Fail, Over Temp, DC Fail and Over Current. These failures
can occur in both single and redundant power supply
control modules and any expansion module with a power
supply.
