7 Checking the LED Indicators

The bridge’s 11a and 11b/g LEDs operate in two display modes, which are configurable through the software. The default AP mode indicates data traffic rates. The RSSI mode indicates the received signal power and is for use when aligning antennas in a bridge link.

When the bridge is connected to power, LEDs indicate as follows:

11b/g

11a

Power Link

LED	Color	Indicates
Power	Green	The bridge is powered up and operating
		normally.
	Off	The bridge is not receiving power or there is a
		fault with the power supply.
	Amber	The system is under cold reset status.
Link	Green	The bridge has a 10/100 Mbps Fast Ethernet
		connection, but there is no activity.
	Flashing	Indicates that the bridge is transmitting or
		receiving data on a 10/100 Mbps Ethernet LAN.
		Flashing rate is proportional to network activity.
	Off	No link is present or the Ethernet LAN port is
		disabled.
11a	Green	The 802.11a 5.3 GHz radio is enabled.
(Three	and	RSSI Mode:
	Flashing
LEDs)		•	One fully lit LED indicates a low RSSI output
			level, two LEDs.a medium level, and three
			LEDs the maximum level.
		•	A flashing LED indicates an intermediate RSSI
			output level

AP Mode:

• One fully lit LED indicates a low traffic rate, two LEDs.a medium rate, and three LEDs the maximum rate.

• A flashing LED indicates an intermediate traffic rate level

	Off	No link is present or the 802.11a radio is
		disabled.
11g	Amber	The 802.11g 2.4 GHz radio is enabled.
(Three	and	RSSI Mode:
	Flashing
LEDs)		•	One fully lit LED indicates a low RSSI output
			level, two LEDs.a medium level, and three
			LEDs the maximum level.
		•	A flashing LED indicates an intermediate RSSI
			output level
		AP Mode:
		•	One fully lit LED indicates a low traffic rate,
			two LEDs.a medium rate, and three LEDs the
			maximum rate.
		•	A flashing LED indicates an intermediate
			traffic rate level
