Quad-port gigabit bypass NIC with Intel I350 controller for firewalls and gateways.
When firewall failover causes network downtime in security appliances, maintaining continuous traffic flow is critical. The LREM3500BP-4T bypass network adapter solves this by ensuring data transmission continues even during system failures.
Built on the Intel I350 controller, this card provides four independent 10/100/1000Mbps RJ45 ports supporting full-duplex operation. Its integrated dual bypass function eliminates single points of failure, enabling uninterrupted service in gateway deployments while saving PCIe slot resources in compact 1U chassis.
Ideal for security gateways and industrial control systems requiring 24/7 uptime, this adapter offers superior reliability compared to standard NICs. The LREM3500BP-4T ensures business continuity through hardware-level bypass protection.
Integrated dual bypass function ensures continuous data transmission during system failures or power loss.
Based on Intel I350 master control chip providing wide system compatibility and stability.
Four network ports with independent gigabit channels working independently to maximize throughput.
Mezzanine structure saves PCI Express channel resources in space-constrained 1U chassis environments.
Supports Data Plane Development Kit for high-performance packet processing applications.
