To Run the Remote
Wake-Up Test
You need at least two PCs on your network that contain a 3Com NIC with
EtherDisk 4.0 (or later) or EtherCD Version 1.0 for the 3CR990 Family software
to run the Remote Wake-Up test.
To run the Remote Wake-Up test:
1 On the first PC, enable Auto Echo:
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 On the second PC, run the Remote Wake-Up test.
To run the Remote Wake-Up test on the second PC:
1 Click Run Remote Wakeup Test on the Diagnostics screen.
The Remote Wake-Up test screen appears.
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
Remote Wake Up Restart button will be unavailable).
3 Enter the number of seconds in the Seconds Until Wakeup entry box that the PC
remains shut down until it receives a wake-up packet from the first PC.
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.
