Dual-port Gigabit Ethernet bypass server adapter based on Intel i350, supporting Normal, Disconnect, and Bypass modes for mission-critical networking.
When critical network segments fail in industrial or mission-critical environments, application downtime can cause significant operational losses. Traditional NICs cannot maintain connectivity if the host system crashes, creating a single point of failure in essential infrastructure.
The LREC9712HT-BP addresses this with hardware-level bypass capabilities. Based on the Intel i350 controller, it supports three distinct modes: Normal, Disconnect, and Bypass. In Bypass mode, packets received from one port are transmitted to the adjacent port, creating a loop-back that keeps the network alive even if the server hangs. This ensures continuous data flow without manual intervention.
This adapter is ideal for implementing multiple network segments in high-powered networking applications. With support for SR-IOV and up to 8 virtual functions per port, it enhances resource utilization in virtualized environments. The integrated Watch Dog Timer allows software control over bypass behavior, providing a robust solution for maintaining network integrity in demanding server deployments.
Ensures maximum network uptime by bypassing failed systems; packets are looped back between ports when the host is down.
On-board WDT controller allows software programmable timeout intervals to manage bypass and disconnect modes automatically.
Based on Intel i350 AM2 MAC+PHY, providing high reliability, low power consumption, and advanced offloading capabilities.
Supports PCI-SIG Single-Root I/O Virtualization with up to 8 virtual functions per port for efficient resource sharing.
Supports 10/100/1000 Mbps auto-negotiation with full duplex and simplex operations for versatile connectivity.
