• For an Ethernet connection:
If the Link LED on the network adapter’s bracket does not light,
check the following items.
- Make sure cable lengths are within the requirements specified.
(See “Making a Connection to the Ethernet Port” on page 13.)
- Inspect all network cables and connections. Make sure the
network cable is securely attached to the network adapter’s
connector.
- Make sure the correct network card driver is installed for your
operating system. If necessary, try reinstalling the driver.
- Make sure the computer and other network devices are receiving
power. If you suspect a power outlet to be faulty, plug another
device into it to verify that it is working.
- If the network adapter’s speed or duplex mode has been
configured manually, check that it matches that of the attached
network device port. Note that it is recommended to set the
adapter to auto-negotiation when installing the network driver.
