Sierra 52264 bypass nic

Sierra 52264

Quad port Ethernet NIC with bypass PCI-e server adapter card
  • RJ45
  • Copper
  • Intel I350- AM4

Sierra 52264 is a quad port Copper Gigabit Ethernet server adapter built on Intel’s Ethernet controller I350- AM4 Gigabit technology and designed with a built-in programmable bypass circuit to provide maximum uptime for the network. The bypass circuit takes the Sierra 52264 ports offline in case of either power or software failure. The bypass circuit works in absence of power.

Sierra 52264 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.

  • Intel I350-AM4 quad MAC and PHY controller
  • Peak bandwidth 5 Gb/s in each direction per PCI Express lane
  • 5 Gigabit per second of traffic when fully utilized
  • PCI-E x 4 (Gen 2.1) compatible
  • Four Copper RJ45 connectors
  • Passive bypass which is essential during power loss or software failure
  • Link Fault Detection (LFD) support
  • Programmable “Fail-Closed” or “Fail-Open” while in the power-off state
  • Programmable independent mode to function as a quad port gigabit copper card
  • Integrated PHY for full and half-duplex 10/100/1000 Base-T Support
  • TCP/UDP/IP checksum offload and TCP segmentation
  • IEEE 802.1q, 802.3ab, and 802.3u compliant
  • Energy Efficient Ethernet (EEE)
  • Layer 2, 3 and 4 advanced packet filtering capabilities (IPv4, IPv6)
  • Low power consumption (9.7 watts maximum power)
  • Full RoHS compliance
  • IEEE 1588 Support
  • FCC and CE certifiable
