Product Details

The 82576EB targets server system configurations such as rack mounted or pedestal servers, where the 82576EB can be used as add-on NIC or LAN on Motherboard (LOM) design. Another system configuration is blade servers, where it can be used as LOM. The 82576EB can also be used in embedded applications such as switch add-on cards and network appliances.

The 82576EB uses an EEPROM device for storing product configuration information. Several words of the EEPROM are accessed automatically by the 82576EB after reset in order to provide pre-boot configuration data that must be available to the 82576EB before it is accessed by host software.

Summary

The 82576EB supports 2 ports with either an internal PHY or a SerDes or SGMII port which may connected to an external PHY or directly to a blade connection for MAC to MAC communication.
