Remote Wake-Up Cable

This procedure applies to 2.1 PCI specification-compliant PCs that support Remote 
Wake-Up using a cable connected to the 3-pin connector on the NIC and the PC 
motherboard.

1

Turn off the PC power, remove the PC cover, and check the Remote Wake-Up 
cable connection.

Make sure that the Remote Wake-Up cable is plugged into the NIC and to the PC 
motherboard. Unplug and reconnect the cable to ensure a good connection.

2

Replace the Remote Wake-Up cable with a known functioning Remote Wake-Up 
cable and perform the Remote Wake-Up test again.

3

If the previous steps have failed, install a known functioning Remote Wake-Up NIC 
in the PC and connect the Remote Wake-Up cable.

If Remote Wake-Up works with the new NIC installed, contact your network 
vendor for a replacement NIC.

If Remote Wake-Up does not work with the new NIC installed, there may be a 
problem with the PC motherboard. Contact your PC vendor.

Troubleshooting a 
Network Connection 

When working with 10BASE-T or 100BASE-TX cabling, concentrators, and NICs 
from different vendors, it is possible to connect everything but still have no 
network communication. 

To narrow the range of possible causes of common network connection problems:

1

Determine whether your equipment complies with the 10BASE-T or 
100BASE-TX standard.

This is particularly important for data concentrators (hubs or repeaters).

NOTE:
