Connect the Ethernet cable, carrying power to J4, the Ethernet and power input, RJ45 connector.
Monitor that the output voltage ramps up to the regulated 12V and is stable.
2. Maximum load, output voltage check.
Connect a scope to the output power solder contacts and set to the scope to the voltage range that
allows measurement of 12V DC.
Connect a 12V, 30W load to the output.
Connect the Ethernet cable, carrying power to J4, the Ethernet and power input, RJ45 connector.
Monitor that the output voltage ramps up to the regulated 12V.
Set the scope to peak detection and measure the noise (high frequency spikes) and ripple
(250kHz triangular oscillation). The noise and ripple should be less than 200mV peak to
peak.
Disconnect the load while the board is powered and connect the load again. Capture the
output voltage during the load step from zero to full load on the scope and check if there’s no
sustained oscillation.
3. Maximum load, Ethernet connectivity
Connect a scope to the output power solder contacts and set to the scope to the voltage range that
allows measurement of 12V DC.
Connect a 12V, 30W load to the output.
Connect the Ethernet cable, carrying power to J4, the Ethernet and power input, RJ45 connector.
Monitor that the output voltage ramps up to the regulated 12V.
Connect another Ethernet cable to J1 and to an Ethernet device. Check that Ethernet data is
passed from the network to the Ethernet device, through J4 and J1, by means of a HTTP, FTP
ping, or Ethernet network traffic analyzer.
