## Summary description

The InLine 51127C is an internal Ethernet network card designed for high-speed wired connectivity. With a maximum data transfer rate of 1000 Mbit/s, it utilizes PCI Express technology for efficient performance. Ideal for enhancing your PC's network capabilities.

## Long description

The InLine 51127C 6-way Gigabit network card is an internal PCIe x4 adapter that provides six RJ45 Gigabit Ethernet ports for reliable wired connectivity in servers, workstations and AV systems. Based on the Intel I350AM4 chipset, the card supports data rates up to 1 Gb/s per port and includes features such as VLAN (802.1Q), Flow Control (802.3x), Jumbo Frames (up to 9K) and Energy Efficient Ethernet (802.3az). Its PCIe v2.1 x4 interface offers sufficient bandwidth for multi-port operation and compatibility with a wide range of system configurations.
Advantages
The adapter delivers stable Gigabit performance across six copper RJ45 ports and uses the Intel I350AM4 chipset for efficient packet processing and reduced resource usage. Support for VLAN tagging, jumbo frames and flow control provides flexibility in complex networks, while Energy Efficient Ethernet reduces power consumption. Compatibility with common server and desktop operating systems and PCIe x4 connectivity ensures easy integration into existing systems.
Suitable for
Servers requiring multiple Gigabit connections
Workstations used for content production or virtualization
Audio–visual (AV) distribution and streaming systems
Network appliances and compact infrastructure with PCIe x4 slots
