Aprisa XE User Manual
Ethernet Port Startup
In previous Aprisa XE software versions, the Ethernet switch ports where enabled when the radio powered
up.
In software version 8.6.53, the mode of operation was changed to disable the Ethernet switch ports until
the radio software has completed booting. This enhancement has been implemented to meet customer
requirements.
A hardware modification is required to the Aprisa XE motherboard to enable this enhancement (0 ohm
resistor fitted).
If the Aprisa XE motherboard hardware modification has been done, the Aprisa XE software version 8.6.53
or greater will be required to operate the radio. If Aprisa XE software prior to this version is used, the
Ethernet ports will not enable. For this reason, an Aprisa XE running software version 8.6.53 cannot be
downgraded to an earlier software version.
