It's a very rare thing to have this happen. MAC addresses are allocated by the IEEE organization and the methods used to prevent this error are very well known.

It means the manufacturer screwed up OR your card has a utility that allows you to change the MAC and soemone has done this.

You should contact your vendor and explain. They may want both of the cards back but at the very least they should replace one of them.

OR find that utility and change the MAC.

Observation only: What you describe is not the "network address", but the MAC address.

The MAC address is a physical address generally burned into the card. Although, as RAFFI_ suggested, in some cases there are utilities for some cards to change the MAC address.

The "network address" is the logical address assigned either manually by an administrator, or automatically by some automated system (e.g., DHCP). A typical network address scheme is IP addressing we all use.

If these are installed in the same machine, it doesn't make a difference since they will be on different networks (hence the MAC will be registering on different ports/NICs of other devices/switches/routers/PCs). There will be no conflict.

Sun SPARCs assign the same MAC to all interfaces (offered as proof-of-concept in case of doubt).

Hope that helps,
