Troubleshooting Remote Wake-Up

If your computer does not boot in response to a Remote Wake-Up event, perform these troubleshooting steps:

1Make sure that the computer meets the Remote Wake-Up Requirements on page 21.

Wake-On-Error is enabled by default.

2Make sure that you are using the latest driver for the NIC.

This driver is shipped with the NIC on the EtherCD. It can also be downloaded from the 3Com Software Library. Point your web browser to the 3Com home page:

Under Service and Support, click Software, Drivers, and INFs.

3Check the computer BIOS.

■Boot the computer and enter the BIOS.

■For instructions on entering the BIOS, consult the computer documentation or contact the computer vendor.

■Locate the Wake-Up on LAN event setting.

■Verify that the setting is enabled.

4Check the Remote Wake-Up cable connection.

If the computer complies with PCI 2.2, the Remote Wake-Up cable is not required. Remote Wake-Up is automatically enabled through the PCI bus.

■Turn off the power to the computer and remove the computer cover.

■Make sure that the Remote Wake-Up cable is plugged in to the RWU connector on the NIC and in to the appropriate connector on the computer motherboard. Unplug and reinsert the cable if necessary.

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