as a hub/switch (and auto-sensing MDI/MDIX cross over is employed), connection can be made
directly to the computer using a standard CAT 5 patch cable.
Before physical installation takes place the units to be installed should be set up as described in
the Section 8.3.4
bench before physical installation commences. Providing it is safe to do so, the installer should
take the process to the point where a radio link is established before proceeding to the installation
site.
NOTE: It is possible that some units may not be accessed using the above default URL. This is
because these units may have been previously configured with IP addresses 10.10.10.11 (Master)
and 10.10.10.10 (Slave). Therefore, users must use the URL http://10.10.10.10/ and/or URL
http://10.10.10.11/ to configure the units. Please ensure that a computer with web browsing
capabilities is configured with an IP address of 10.10.10.n, where n is any value between 2 and 254
but excluding 10 and 11, to configure these units.

The following is a description of the steps taken to establish a radio link between the two units
forming the bridge and align the units for the best signal strength.
The PTP 500 Series Bridge uses audible tones during installation to assist the installer with
alignment. The installer should adjust the alignment of the ODU in both azimuth and elevation
until highest pitch tone is achieved
