a Open the 3Com NIC diagnostics program and make sure that Auto Echo is
enabled on the General screen.
b Close the 3Com NIC diagnostics program.
c Make sure that the PC remains powered on and connected to the network.

2 Click 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.
If the test passes, another PC with the Auto Echo feature enabled was detected on
the network.
If the test fails, another PC with the Auto Echo feature enabled was not detected
on the network. You will not be able to run the Remote Wake-Up test (the

remains shut down until it receives a wake-up packet from the first PC.

that is installed in the PC does not support Remote Wake-Up or Magic Packet
is not enabled.
