The RLS Power Supply Module(s) must be removed before a DIA can be replaced. The
DIA type (Quick / Hot swappable) installed can be changed at this time. No calibra-

The pins of the four Channel(1-4) connectors on both sides of the Drive Bay
PCBA Assembly are easily bent while working around the PCBA. If a bent pin
is not straightened perfectly before a Tape Drive or DIA PCBA is installed, it is
quite likely that the pin will get permanently damaged during the insertion of
the mating connector.

Remove power from the RLS by first pressing the power switch off and then re-
moving the power cord (two power cords if dual-redundant power supply mod-
ules are installed).
