5.6 SYSTEM ALIGNMENT BASICS
After finishing the mounting of the antennas, and connecting the cabling as described in Chapter 3,
the system is ready for alignment. During the alignment procedure it is only required to power on the
radio, and active network traffic is not needed to align the system. The radio will automatically switch
to the
alignment mode when it is installed for the first time. To verify that the system is in Alignment
Mode , observe the ALIGN LED the user panel. A lit LED indicates that the system is in active alignment
mode . Regardless of the system being connected to the network via one of the data port, no traffic
will pass across the radio link until the system is switch from Alignment Mode into D ata Mode. See
Chapter 6.3 on how to switch the system from the Alignment Mode into D ata Mode using the web
browser interface. After the alignment is completed it is important to save the system setting in using
the Administrative sub menu in the web browser (see Chapter 6.9). Without saving the settings the
system will come up in
Alignment Mode rather than in Data Mode each time the power is recycled.
The radio will be in Alignment Mode when installed for the first time and the
alignment LED on the backpanel will be lit. To enable data transmission the
system must be switched into
Data Mode. The new setting must be saved to
avoid the system rebooting in Alignment Mode after power is recycled.
The alignment process itself will be eased if two people (one on each side) are involved in the alignment
procedure. This is particularly true for the larger AireLink™ 60 with the 2 foot antenna option due to
its narrower beam pattern when compared to the smaller AireLink™ 60 with the integrated 12 cm
antenna or the external 1 foot antenna. Two-way radios or cell phones are extremely helpful in
exchanging information between the two parties performing the alignment. While it is possible for a
single individual to align the units, walking or driving back and forth between the two mounting
locations can be a cumbersome and time consuming process. The correct alignment of the system is
crucial for ensuring proper performance of the system and no rush should be in play when aligning the
system. Depending on the experience of the installer(s) in aligning narrow beam radio transmission
equipment and the actual antenna used, this process can take anywhere from 15 to 90 minutes.
