Sierra 32265

Dual Port Copper Gigabit Ethernet NIC with Bypass PCI-e Server Adapter Card

Sierra 32265 dual port Gigabit Ethernet server adapter is built on Intel’s 82576 Gigabit technology and Interface Masters’ sterling design and customer service.
Sierra 32265 is designed with a built-in programmable bypass circuit to provide maximum uptime for the network. The bypass circuit takes the Sierra 32265 ports offline in case of either power or software failure. The bypass circuit works in absence of power.
Sierra 32265 dual port Copper Gigabit Ethernet NIC is designed to integrate with PCI Express compatible servers and high-end appliances providing high speed networking and bypass/failover capabilities for any mission-critical application.
