Lenovo 7ZT7A00544 network card Internal Ethernet 1000 Mbit/s

The Lenovo 7ZT7A00544 Internal Ethernet 1000 Mbit/s is a wired network card designed to provide stable gigabit connectivity for desktop and server systems with an available PCI Express slot. With support for standard Ethernet protocols and a maximum data transfer rate of 1000 Mbit/s, this internal card delivers predictable network throughput for general office, home, and light server workloads. The card combines a green and metallic finish with a compact PCB layout to fit into standard PCIe expansion bays.

Advantages

The network card supports widely used networking standards to ensure compatibility with managed switches and modern network infrastructures. Its PCI Express host interface allows direct integration into systems without requiring external power or adapters. The wired connectivity and gigabit transfer rate reduce latency and provide stable throughput for file transfers, backups, and networked applications. The compact internal design keeps the installation footprint small while offering durable metallic components where needed.

Suitable for

• Adding gigabit Ethernet connectivity to desktops and workstations
• Upgrading server or tower systems requiring a PCI Express network interface
• Networked file transfers, backups and small office networks
• Environments that require stable wired connections with support for VLAN and QoS

Key specifications

• Connectivity technology: Wired Ethernet
• Host interface: PCI Express
• Maximum data transfer rate: 1000 Mbit/s (Gigabit Ethernet)
• Supported networking standards: IEEE 802.1Q, IEEE 802.1Qbg, IEEE 802.1p, IEEE 802.3ad, IEEE 802.3x
• Form factor: Internal PCIe add-in card (standard low-profile/regular profile compatible—verify bracket if needed)
• Product colour: Green and metallic components

How to use

Install the card into an available PCI Express slot on a powered-off system, secure it with the slot bracket, and connect the Ethernet cable to the RJ‑45 port on the card (if present on the model). Power on the system and install operating system drivers where required; modern operating systems may automatically recognize the device and load a suitable driver. Configure IP addressing, VLANs or QoS policies using the operating system or network management tools to match your network environment.

Recommendations

For optimal performance, connect the Lenovo 7ZT7A00544 to gigabit-capable switches and use quality CAT5e or higher Ethernet cabling. Keep firmware and drivers up to date to maintain compatibility with network management features such as VLAN tagging and flow control. If installing in a server chassis, confirm slot availability and bracket type (full or low-profile) before installation.
