The indicator signals on the wireless device have the following meanings (for additional details refer to
Table 17-1):
• The Ethernet indicator signals traffic on the wired LAN. This indicator is normally green when an
Ethernet cable is connected, and blinks green when a packet is received or transmitted over the
Ethernet infrastructure. The indicator is off when the Ethernet cable is not connected.
• The status indicator signals operational status. Steady green indicates that the wireless device is
associated with at least one wireless client. Blinking green indicates that the wireless device is
operating normally but is not associated with any wireless devices.
• The radio indicator blinks green to indicate radio traffic activity. The light is normally off, but it
blinks whenever a packet is received or transmitted over the wireless device radio.
