System maintenance switch (SW1)
CAUTION:
All supported AMD Opteron quad-core processors 3.1 GHz or greater and all
supported AMD Opteron six-core processors require the system maintenance switch, located on
the I/O backplane, (SW1) position 5 to be in the On position.

HP recommends updating to the latest version of firmware. Earlier firmware versions might not
validate the required switch setting for these processors.

The system is powered down, and the cache contains data that has not yet
been written to the drives. Restore system power as soon as possible to
prevent data loss.
Data preservation time is extended any time that 3.3 V auxiliary power is
available, as indicated by LED 2. In the absence of auxiliary power, battery
power alone preserves the data. A fullycharged battery can normally preserve
data for at least two days.
