Using LEDs to Check the State of the Adapter
The LEDs function as link and data indicators once the InfiniPath software has
been installed, the driver has been loaded, and the fabric is being actively
managed by a subnet manager.
Table D-1 describes the LED states. The green LED indicates the physical link
signal; the amber LED indicates the link. The green LED normally illuminates first.
The normal state is Green On, Amber On. The QLE7240 and QLE7280 have an
additional state, as shown in Table D-1.
