ZyXEL Communications A-6000 manual Indoor Interface Unit, System LED Indication

A-6000 High Speed, Long Range Ethernet Wireless Bridge

3.Connect the other end of the RS-232 cable to the antenna alignment kit AK-100. Adjust the horizontal angle of directional antenna to get the maximum reading in the LEVEL and SNR display of AK-100. You may also refer to the SNR and RSSI reading shown in the Wireless Information of the WEB server. Please be noticed that If you align the antenna according to the SNR and RSSI reading from the WEB server, the POE and NoteBook PC should be located near the antenna position. Use an extended power outlet to supply the RU source of POE and after the alignment is completed, put the POE back to the indoor position.

Note: The PWR and ACT LED will be ON when connect the AK-100 to the A-6000.

4.Adjust the vertical angle of directional antenna to get the maximum reading in the LEVEL and SNR display or the SNR and RSSI reading shown in the Wireless Information of the WEB server.

5.Repeat step 3 and step 4 until achieving the best reading index, then remove the antenna alignment kit.

Note: The AK-100 will beep more rapidly while getting better link quality. It beeps continuously after the best link quality is achieved.

6.Put the console port cover back to the console port.

Note: The signal strength should be well aligned on both the Remote unit (RU) and Basestation unit (BU).

2.6 Indoor Interface Unit

The front panel LEDs of indoor interface unit and functionality are listed below:

Function	Naming	Color	Description
Power	PWR	Green	ON: The RU power is properly applied to the indoor unit
			OFF: The power is disconnected or the fuse is blown
System	SYS	Green or	ON and Green: The link to the outdoor unit is established
		Red	ON and RED: A serious fault of A-6000 is detected
RSSI L, M, H	RSSI (L,	Green	ON: The receive signal strength link to remote A-6000 is established
	M ,H)		OFF: The RF propagation path to remote A-6000 is not ready Note: L
			is ON: the signal strength is Low L, M are ON: the signal strength is
			Medium L, M, H are all ON: the signal strength is High
Signal Quality	SNR	Green	ON: The PER is less than 8%
			OFF: The PER is larger than 8%
LAN	LAN 10M	Green	ON: The LAN 10/100M connection is established Flash: The LAN
	LAN 100M	Orange	10/100M interface is transmitting/receiving
			OFF: The LAN 10/100M connection is not ready

2.7 System LED Indication

For easily configuring A-6000 system status, we reserve system LED in IDU to indicate whether system run in ok state or in failed state. If system LED is green light, that means system ok; if system LED flash with red/green light, it means system is disconnected; once in red light, it means A-6000 500A with some system errors there. There are some events to lead system LED into red light mode; and events are listed as following:

ODU/IDU connection fails.

END devices Init Fail.

BU init fails.

Memory Allocate Descriptor error.

H/W Allocate Descriptor error.

BU Trap Monitor Task.
