To run the Remote Wake-Up test on the second PC:

1Click Run Remote Wakeup Test on the Diagnostics screen. The Remote Wake-Up test screen appears.

NOTE: If the Run Remote Wakeup Test button is not available, either the NIC that is installed in the PC does not support Remote Wake-Up or Magic Packet is not enabled.

2Click Test Remote Wake Up to verify that another PC exists on the network that has the EtherDisk 4.0 (or later) or EtherCD Version 1.0 for the 3CR990 Family software and that Auto Echo is enabled on that PC.
