12. Expansion port LEDs
For E60/E48/V/VT controllers:
There are two LEDs (
L0
and
L1
), each indicating the connection status for an expansion port. Green
indicates that the SAS cable is properly connected. Flashing amber indicates that the cable is improperly
connected. If no cable is connected, this LED is off.
For E60P/E48P controllers:
Each connector has two LEDs below it. If neither is lit the port is disabled or disconnected. A green light
indicates that the connection is healthy, a flashing red light indicates an incorrectly attached cable, and a
flashing red light indicates that the connection may be faulty.
13. Management port LEDs (activity and speed): The left LED flashes green when there is port activity. The
right LED lights up green when there is a 100Mb/s connection. When there is only a 10Mb/s connection,
the right LED is off.
14. Controller status LED (
STAT
): Indicates the status of the RAID Controller.
For E60/E48/V/VT controllers:
Solid blue indicates that the controller is operating within specifications and that there is no user data
in the cache.
Solid green indicates that the controller is operating within specifications and that there is user data in
the cache, which will be retained in flash memory upon power-down and then restored when the unit is
powered up again.
Flashing red (once per second) indicates that the controller is offline due to a fault being detected.
Flashing green (twice per second) indicates that the controller is operating in battery-backup mode
and is backing up cached data to flash memory. This can take several minutes.
Alternating blue and red indicates that the controller is booting in Emergency mode (see
Switches
below).
For E60P/E48P controllers:
Solid green indicates that the controller is operating within specifications.
Flashing red (once per second) indicates that the controller is offline due to a fault being detected.
Solid red indicates that the controller has been deliberately stopped.
Flashing green (twice per second) indicates that the controller is operating in battery-backup mode
and is backing up cached data to flash memory. This can take several minutes.
Alternating red and green indicates that the controller is booting in Emergency mode (see
Switches
below).
15. iSCSI port LEDs (activity and status): For 1Gb/s connections, the left LED illuminates green when the
power is connected, and both LEDs flash green when there is activity.
