IP Products: What is LQ Link-Local mode?
A link-local address is an IP address within the local segment of any network. Routers do not pass information to these as
link-local addresses are not guaranteed to be unique beyond a single network segment. When first connected to a network,
your LQ device will attempt to get an IP address via Dynamic Host Configuration Protocol (DHCP). If no DHCP server is
available the unit will automatically enter link-local IP mode. A link-local IP address will take the form: 169.254.xxx.xxx.
To access the CCM (web browser setup) an LQ unit in link-local, you must connect to it from a PC that is also in link-local mode.
Devices will revert to link-local mode if they are configured to DHCP and fail to find a DHCP address on the network or device
they are attempting to connect to. A PC can be put into link-local mode by ensuring it is in DHCP mode and connecting it to
the LQ unit that is in link-local with a standard Ethernet cable. The PC will look for a dynamically generated IP address (DHCP),
and when it does not find one will enter link-local mode automatically.
Once the PC is connected to the LQ and in link-local mode, you can connect to your LQ unit by opening a browser window on
the computer and inputting the LQ unit’s IP address (from the front panel display) into the address field. This takes you to the Core
Configuration Manager where you can configure the device as usual.
Note: The units will operate in link-local, but for optimum performance it is recommended that they are used with either static or DHCP network settings.
