The Lenovo 7ZT7A00484 is a four-port Gigabit Ethernet adapter that adds dependable, copper-based network connectivity to Lenovo ThinkSystem and ThinkAgile servers. Built for administrators who need more ports without sacrificing PCIe slots, it delivers four RJ45 connections through a single PCI Express 2.0 x4 interface, making it easy to consolidate network links or create dedicated traffic lanes for management, storage, or backup.
At the heart of the adapter sits the Broadcom BCM5719 controller, a proven network processor that handles heavy traffic with features such as Receive Side Scaling for balanced CPU utilization and TCP/UDP checksum offload to reduce host overhead. Support for jumbo frames up to 9600 bytes enhances throughput during large data transfers, while IEEE 802.1Q VLAN tagging and IEEE 802.3x flow control help keep packets organized and flowing smoothly.
IT teams who rely on remote or automated deployment will appreciate built-in PXE boot capabilities, and environments that boot from the network can take advantage of iSCSI boot support. Whether you deploy the card in a compact server that needs a low-profile bracket or in a standard rack unit that uses a full-height bracket, everything required ships in the box.
Typical use cases include virtualization hosts that run many guest machines, hyperconverged nodes that separate storage and management traffic, and small business file servers that demand reliable links for daily backups. Wherever you need dense, cost-effective Gigabit Ethernet connectivity, this adapter offers a straightforward, Lenovo-qualified solution.
