Check the appropriate indicator on the NIC connector. See "NIC Indicator
Codes" on page 21.

be damaged or missing.
Remove and reinstall the drivers if applicable. See the NIC's
documentation.
• Change the autonegotiation setting, if possible.

If you are using a NIC card instead of an integrated NIC, see the
