Lenovo 7ZT7A00545 4-port 1000Base-T network switch

SKU CH-BKKC-VK51F MPN 7ZT7A00545

A four-port 1000Base-T plug-in card that adds Gigabit Ethernet connectivity to a server over twisted-pair cabling

  • Supported protocolsTCP/IP
  • Product weight0.55
  • Four 1 GbE RJ-45 ports for copper uplinks
  • PCI host interface slots directly into server backplane
  • Twisted-pair media support uses existing Cat 5e/6 cabling
  • China RoHS certified for regulated deployments
  • Plug-in card form factor adds networking without occupying a PCIe slot

Four-Port 1000Base-T Server Adapter

This Lenovo ThinkSystem plug-in card adds four RJ-45 ports to a server over a PCI host interface. It runs at 1000Base-T speeds using twisted-pair cabling and is built for data-centre environments. The adapter weighs 0.55 kg and carries China RoHS certification.

Suited For Single-Server Expansion

IT teams adding copper connectivity to one rack server will find the four ports convenient. Buyers who need more than four ports, fibre uplinks or a standalone switch chassis should evaluate other form factors. The card fits only systems with an available PCI slot.

PCI Host Interface Determines Compatibility

The card communicates with the host through a PCI bus, so the server must expose a matching slot. If the platform offers only PCIe or OCP slots, this adapter will not install. Verify the motherboard layout before ordering.

Questions about this item

Does my server have a free PCI slot for the 7ZT7A00545 adapter?

Yes — the card plugs into a standard PCI slot, so the host must provide one open PCI connector.

Will the four 1000Base-T ports negotiate down to 100 Mbps for older switches?

Each RJ-45 port supports 1000Base-T and will auto-negotiate to 100 Mbps or 10 Mbps when linked to legacy equipment.

How can I confirm all four ports are passing traffic after installation?

Check the link LEDs on each RJ-45 port; a solid light means a live 1000Base-T connection, while blinking shows data activity.
