EXSYS Dual 5 Gigabit Ethernet PCIe x2 Card (Realtek RTL8126) EX-60152

The EXSYS EX-60152 adds two independent 5 Gigabit Ethernet ports over a single PCIe 2.1 x2 slot, using the Realtek RTL8126 controller. Unlike single-port adapters, this card lets one machine handle two 5G links without occupying a second expansion slot.

Highlights

• Dual RJ45 ports, each supporting 100M/1G/2.5G/5G speeds with auto-negotiation
• PCIe 2.1 x2 host interface, compatible with x2, x4, x8, and x16 slots
• Low profile form factor with both standard and low profile brackets included
• Supports Wake-on-LAN, PXE boot, jumbo frames up to 16 KB, and checksum offload

In daily use

The card installs in a wide range of desktop and server systems. Its low profile design fits compact cases, while the standard bracket suits full-height slots. With support for Windows, Windows Server, Linux, and macOS up to 10.15, it integrates into mixed environments. The dual ports allow link aggregation, failover, or dedicated connections for separate networks.
