Lenovo 4XC1K83390 network card Internal Ethernet 1000 Mbit/s

The Lenovo 4XC1K83390 is an internal Network Card designed for PCI Express slots that provides dual-port Gigabit Ethernet connectivity with a maximum data transfer rate of 1000 Mbit/s. Based on the ThinkStation Broadcom BCM5720-2P design, the adapter supports standard wired Ethernet interfaces and common IEEE networking standards to ensure reliable wired network performance for desktop and workstation systems.

Advantages

The card supports offload technologies such as Large Send Offload, TCP segmentation offload and TCP/UDP/IP checksum offload, as well as receive-side scaling (RSS) to improve network throughput and reduce host CPU utilisation. Its PCI Express host interface and compliance with IEEE 802.3ab/802.3x/802.3az standards make it compatible with typical wired network environments and energy-efficient network equipment.

Suitable for

• Desktop PCs and workstations requiring reliable wired Gigabit Ethernet
• Office networks with high-throughput file sharing and standard LAN services
• Home networks where a stable wired connection is preferred over wireless

How to use

Power off the computer and insert the Lenovo 4XC1K83390 network card into an available PCI Express x1 slot, securing it to the chassis. Connect standard Ethernet cables to the card’s RJ-45 ports and to your network infrastructure (switch, router, or modem). Power on the system and install drivers if the operating system does not automatically recognise the adapter. Configure network settings through the OS network manager or your IT policies.

Recommendations

Install the latest vendor drivers and firmware updates for optimal performance and enable offload features and RSS in driver settings when supported by your operating system and network stack.
