Bypass nic Niagara 52285/Sierra-52285

Sierra 52285

Dual port Ethernet NIC with bypass, low profile PCI-e server adapter card
  • LC connectors
  • Fiber
  • Intel I350-AM2

Sierra 52285 is a dual port Gigabit Ethernet server adapter built on Intel’s I350 Gigabit technology and designed with a built-in programmable bypass circuit to provide maximum uptime for the network. The bypass circuit takes the Sierra 52285 ports offline in case of either power or software failure. The bypass circuit works in absence of power.

Sierra 52285 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-AM2 dual 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
  • Dual LC connectors
  • Multi-mode Fiber (SX), single-mode Fiber (LX)
  • Low profile form factor
  • 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 dual port gigabit fiber card
  • TCP/UDP/IP checksum offload and TCP segmentation
  • IEEE 802.1q, 802.3 compliant
  • Layer 2, 3 and 4 advanced packet filtering capabilities (IPv4, IPv6)
  • Low power consumption (6.1watts maximum power)
  • Full RoHS compliance
  • FCC Class A and CE certification
