Abstract
The system provides an IP network card that comprises a redundancy configuration register; an interface; and redundancy mapping logic. The redundancy configuration register stores card configuration data. The interface receives slot active signals from other cards. The redundancy mapping logic is communicatively coupled to the register and interface. The logic maps a packet to a slot having an active card based on the data in the register, an address in the packet, and received slot active signals.
