If radio links are chained together to form a radio backbone, it is also important to consider the
operation of the Layer 3 Transparent Bridge (Refer Section 3.7). A XYR 400E Client will act as a
MAC Address translator, as it acts as a MAC address proxy on behalf of devices connected to its
wired Ethernet port. Addition of XYR 400E Client MAC addresses into intermediate XYR 400E
units' whitelist filters may be required for correct operation.
It is advisable to use the Apply Changes button to test the configuration entered. Once the
configuration is determined to be correct, the Apply Changes and Save button should be used. In
the event that the configuration is incorrect, a power reset will revert the unit to previously saved
configuration.
If an erroneous configuration has prevented all access to the module, SETUP mode may be
used analyze what is wrong with the configuration. Simply switch the dipswitch to SETUP and
cycle power. The XYR 400E will retain its configuration, however will load up at IP address
192.168.0.1XX, netmask 255.255.255.0 with the radio and filter disabled. The XX in the IP address
is the last two digits of the serial number. Configuration webpages will still show the original
configuration. No changes are made to configuration until the user saves changes. To resume
normal operation, set the dipswitch to RUN and cycle power.
