The MTBF for the tabletop drive power supply is 50,000 hours with the
unit operated at full load and 25°C.
Note: The MTBF rating does not represent any particular drive, but
is derived from a large database of test samples. Actual rates
may vary from unit to unit.
The mean time to replace (MTTR) is the average time required by a
1
qualified service technician to diagnose a defective drive and to install a
replacement drive. The MTTR for LTO products is less than 0.5 hour (30
minutes).
The Quantum LTO drives are field-replaceable units. If a problem occurs
with a subassembly or component in the drive, you should replace the
entire unit. Return the drive to the factory in its original packaging.
Contact your distributor, dealer, your computer system company or your
Quantum sales representative to arrange the return.
