5.7.8 Powering Up
Prior to powering up the OS-Gemini, a computer with web browsing capabilities should be
configured with an IP address of 10.10.10.n and subnet mask of 255.0.0.0 where n is any value
between 1 and 254 but excluding 10 or 11. If the default address of the unit 10.10.10.10/11
clashes with an address you are already using on your LAN, or you are not sure, you should
set up an isolated LAN. As the LAN connection presented at the IDU has a default
configuration 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.
The Gemini system is supplied as a pair of matched Master/Slave units. The Master unit to be
configured can now be powered up and accessed using the default URL
http://10.10.10.10/;
the Slave unit can be accessed using
http://10.10.10.11/.
Before physical installation takes place the units to be installed should be set up as described
in the section 6.3.3. This process will give the installer the opportunity to set the units IP
address to one that is in the desired address range and set each unit up with the MAC address
of its peer unit ready to establish a radio link. It is recommended that this procedure be carried
out on the 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.
