Sierra 42264 is a quad-port Gigabit Ethernet server adapter, built on Intel’s 82580 Gigabit technology and designed with a built-in programmable bypass circuit to provide maximum uptime for the network. The bypass circuit takes the Sierra 42264 ports offline in case of either power or software failure. The bypass circuit works in absence of power.

Sierra 42264 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.
