6 Enclosure mode
switch
The function of this switch is not applicable to
your storage array. However, if MD1200 Series
expansion enclosures are daisy chained to the
storage array, the enclosure mode switches of the
MD1200 Series expansion enclosures must be set
to the Unified-Mode position.
NOTE: This switch must be set before turning on
the MD1200 Series expansion enclosure. Changing
the switch setting after the expansion enclosure is
turned on has no effect on the enclosure
configuration until the expansion enclosure goes
through a complete power cycle.
