Warning to Service Personnel: 48 VDC
Customer equipment including personal computers, routers, etc., must be connected
only to the INPUT (DATA) port on the PoE unit.
Only the outdoors Ethernet interface cable connecting to the AN-80i can be safely
connected to the OUTPUT (DATA & POWER) connector. Connecting customer
premises Ethernet equipment directly to the OUTPUT (DATA & POWER) connector
on the Power-over-Ethernet power adapter may damage customer equipment.
2.6 Antenna
Alignment
The AN-80i includes both an audible alignment tool and a web-based alignment tool to
assist in pointing the antenna.
2.6.1 Web Page Alignment
The most reliable method for obtaining optimum performance from a wireless link is by
fine alignment of the antenna to the position providing the highest RSSI (received signal
strength indication) and best SINADR (signal to noise & distortion ratio). The web page
assists this alignment by providing continuous updates of RSSI and SINADR values at
one second intervals. Note that SINADR is available only on PTP systems.
The web page can be accessed directly from a link on the System Status screen
(
Antenna Alignment
).

You may also use the following URL to access the web alignment page directly from a
laptop computer and most web-enabled handheld devices:
http:// [AN-80i IP Address] / usr / aa.html
For example: http:// 192.168.20.25 / usr / aa.html
2.6.2 Audible
Alignment
The signal will sound infrequently when a low signal is detected, and more often as the
signal strength increases. The audible signal is enabled and disabled through the user
interface:
Web: See
Antenna Alignment Buzzer Enable
in Web System Configuration screen.
Telnet: See '
buzzer'
in CLI 'set' commands.
The audible antenna alignment tool provides only rough adjustment for the subscriber
antennas. It is recommended to monitor the RSSI measurements to achieve maximum
signal strength when performing fine adjustments to the subscriber antenna. Refer to the
AN-80i Installation Guidelines for detailed instructions.
