Interface Masters | Niagara 32285 | Dual Port Fiber Gigabit Ethernet NIC with Bypass | Low profile PCI-e Server Adapter Card


  • Niagara 32285 Dual Port Gigabit Ethernet Server Adapter is built on Intel’s 82576 Gigabit technology & Interface Masters’ sterling design and customer service.
  • Niagara 32285 is designed with a built-in programmable bypass circuit to provide maximum uptime for the network. The bypass circuit takes the Niagara 32285 ports offline in case of either power or software failure. The bypass circuit works in absence of power.
  • Niagara 32285 Dual Port Fiber 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.



  • Intel 82576EB Dual MAC & PHY controller
  • Peak bandwidth 5 Gb/s in each direction per PCI Express lane
  • 4 Gigabit per second of traffic when fully utilized
  • PCI-E x4 (Gen 2.0) 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
  • Integrated PHY for full and half-duplex Support
  • TCP/UDP/IP checksum offload and TCP segmentation
  • IEEE 802.1q, 802.3ab, 802.3u, 802.3x compliant
  • Layer 2, 3 and 4 Advanced packet filtering capabilities (IPv4, IPv6)
  • Efficient form factor – 6.67 inches in length and 2.51 inches in height
  • Low power consumption (7W maximum power)
  • Full RoHS compliance
  • FCC Class A and CE certification
