NIC2:• Indicates network activity on GLAN2 when fl ashing.
Overheat/Fan Fail:• When this LED fl ashes it indicates a fan failure. When
continuously on (not fl ashing) it indicates an overheat condition, which may be
caused by cables obstructing the airfl ow in the system or the ambient room
temperature being too warm. Check the routing of the cables and make sure
all fans are present and operating normally. You should also check to make
sure that the chassis covers are installed. Finally, verify that the heatsinks are
installed properly. This LED will remain fl ashing or on as long as the overheat
condition exists.
