indicates the presence of a
Critical System Fault, which is
an error or event with a fatal
system impact. In this case, the
system cannot continue to
operate. An example is the loss
of a large section of memory, or
other corruption that renders the
system not operational.
When continuously lit, this
indicates the presence of a Major
System Fault, which is an error
or event which has a discernible
system impact. In this case, the
system can continue to operate
but in a degraded fashion
(reduced performance or loss of
non-fatal feature reduction). An
example is the loss of one or two
mirrored disks.
