Description
Blinks blue when a host server is identifying the
enclosure or when the system identification button
is pressed.
Lights amber as enclosure boots or is reset.
Blinks amber when the enclosure is either in a fault
state or the hosts are not using the preferred path
to a virtual disk.
The power LED lights green when at least one
power supply is supplying power to the enclosure.
This LED must be unlit as the split mode function is
not supported by the MD3800f 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.
MD3800f —Up to twelve 3.5 inch SAS hot-
swappable hard drives.
MD3820f —Up to twenty four 2.5 inch 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.
