Troubleshooting Remote Wake-Up
85
Troubleshooting Remote Wake-UpIf 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 6.
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:
http://www.3com.com/
Under “Service and Support,” click Software, Drivers, and INFs.
Check the network
connection
■Inspect all cables and connections. Make sure that the cable complies with
length and rating specifications described in “Installing and Connecting
the NIC” on page 18.
■Examine the cable for obvious signs of damage, wear, or crimping.
Substitute a known working cable. Check the length and rating of the
cable. Make sure that the cable complies with 10BASE-T or 100BASE-TX
recommendations.
Check the
computer BIOS
Make sure that you are running the latest BIOS for your computer. If the BIOS
has not been upgraded in the previous 12 months, contact the computer
manufacturer to obtain the current version of the BIOS software.
Run the NIC
diagnostic tests
Run the NIC and Network Tests, as described in “Running NIC Diagnostics” on
page 91.
If the tests fail, replace the NIC with a known working NIC and run the tests
again, using the same configuration settings as those used on the failed NIC. If
the working NIC passes all tests, the original NIC is probably defective. For
information on product repair, see “Technical Support” on page 109.
