Module front panel LEDs	STATUS •Green—All diagnostics pass; the module is operational. •Orange—The module is booting or running diagnostics; an overtemperature condition has occurred. LINK •Green—The port is active (the link is connected and operational). •Flashing orange—The port failed diagnostics and is disabled. •Orange—The port is disabled. •Red—The module is resetting; an overtemperature condition has occurred. Note If the module fails to download code and configuration information successfully during the initial reset, the LED stays red; the module does not come online. •Off—The port is not active or the link is not connected.
