Summary Fault
LED)
General machine
fault A Fault LED is lit somewhere on
the storage expansion enclosure
(check for Amber LEDs on
FRUs).
Fibre-channel
connection failure Check that the FRUs are properly
installed. If none of the amber
LEDs are lit on any of the FRUs,
this indicates an SFP module
transmission fault in the storage
expansion enclosure. Replace the
failed SFP module. See the DS
Storage Manager software
documentation for more
information.
