Problem indicator Component Possible cause Possible solutions
Amber LED is lit
(continued) storage controller
fault LED (service
action LED may
also be lit) Unsupported controller Controller configurations do not match.
Check that host daughter card and cache
memory are the same in both controllers.
Front panel Fibre Channel connection
Check that the CRUs are properly
installed. If no amber LEDs are lit, suspect
failure of the SFP module. Verify the
failure using the Storage Manager Client.
If all Fibre Channel connections failed,
suspect failure of the Fibre Channel host
daughter card.
SAS connection
Check the SAS connection to verify that
the CRUs are properly installed.
If the SAS port LED is off, suspect failure
of the SAS host daughter card.
iSCSI connection
Check the iSCSI connection to verify that
the CRUs are properly installed.
If the iSCSI port LED is off, check the
Ethernet cable or verify the link speed.
If all the iSCSI port LEDs are off, suspect
failure of the iSCSI host daughter card.
Battery fault Battery unit failure Verify the failure using the Storage
Manager Client and replace the failed
battery.
Amber LED is lit and
green LED is off
Power supply
(Amber fault LED is
lit and both power
LEDs are not lit)
The power switch is
turned off or there is an
ac or dc power source
failure. Replace the failed power supply or turn
on all power-supply switches. If this is a
dc power supply, check the disconnect
device to make sure that it is working and
is in the on position.
Amber and green LEDs
are lit
Power supply
(Amber fault LED is
lit and both power
LEDs are not lit, AC
power or DC IN
LED is lit and DC
power or DC out
LED is not lit)
Power supply failure Replace the failed power supply. See
Chapter 5, “Replacing components,” on
page 5-1 for more information.
All amber and green
LEDs are slowly
flashing All drives
(activity and fault
LEDs are not lit)
Check for and solve one of the following situations:
v
storage enclosures are not correctly connected to the DS3500.
v DS3500 does not have the correct firmware version.
