The Power Supply Module(s), all Tape Drives, all Drive Interface Adapters (DIAs),
the Sensor Master Assembly and the X-Clear Emitter PCBA must be removed from
the RLS before the drive bay PCBA can be replaced. No calibration is required after
replacing the Drive Bay PCBA FRU.
The pins of the four Channel (1-4) connectors on both sides of SCSI Drive Bay
PCBA Assemblies are easily bent while handling the board. If a bent pin is not
straightened perfectly before a Tape Drive or DIAs is installed, it is quite likely
that the pin will get permanently damaged during the insertion of the mating
connector.
The DFA Drive Bay PCBA Assemblies (P/N 501957-01-3) only have connectors
with pins on the side that faces the Tape Drives, but equal care should be
given when handling. A bent pin that is not straightened perfectly before a
Tape Drive is installed is quite likely to get permanently damaged during the
insertion of the mating connector.
