Planning: About Your Storage Array
Icon Description
This LED must be unlit as the split mode
function is not supported by the MD3200 Series
Storage Arrays.
The system identification button on the front
control panel can be used to locate a particular
enclosure within a rack. When the button is
pushed, the system status indicators on the
control panel and the RAID controller module(s)
blink blue until the button is pushed again.
MD3200—Up to twelve 3.5" SAS hot-swappable
hard drives.
MD3220—Up to twenty four 2.5" SAS hot-
swappable hard drives.
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.
