Dot Hill Systems II 200 FC service manual 6.3.2 I/O Expansion Module LEDs

Note – Ethernet link LEDs on SANnet II 200 FC, SATA, and SATA SE arrays differ from the Ethernet link LEDs found on SANnet II 200 SCSI arrays and SANnet II 220 SCSI arrays. On SANnet II 200 FC, SATA, and SATA SE arrays, a connected port’s Ethernet link LED glows solid amber only on the active controller, because the Ethernet port on an FC array is considered active only if its controller is active. On an inactive controller, a port’s Ethernet link LED is off whether the port is connected or not. The absence of a solid amber light on a connected port’s Ethernet link LED indicates that this controller is not the active controller.

Note – An SFP link status (L) LED is off if there is no connection or a failed connection to this SFP. This does not apply to SATA SE arrays because they do not include SFPs.
