Lenovo 10Gb 2-port SFP+ LOM

This Lenovo ThinkSystem adapter provides two 10Gbps SFP+ ports over a PCI-Express interface. It is designed for servers or workstations that need high-speed wired connectivity for storage or cluster traffic. The card adds 10Gigabit Ethernet capability to systems with an available PCIe slot.

Fits a standard PCI-Express slot

The adapter occupies a single PCIe slot and uses SFP+ transceivers for fibre or direct-attach cables. It frees onboard 1GbE ports for management while the two 10Gbps lanes handle bulk data. No additional power connectors are required beyond the slot itself.

Sustained 10Gbps throughput

Under continuous load the card maintains line-rate 10Gbps per port without thermal throttling. The low-profile bracket keeps airflow clear in dense chassis. Latency remains consistent during long transfers, making it suitable for backup windows or replication jobs.

Questions about this item

How many SFP+ ports does the Lenovo 7ZT7A00546 provide for 10Gbps connectivity?

The card provides two SFP+ ports, each operating at 10Gbps for high-speed network connections.

What is the power draw and thermal output of the 7ZT7A00546 during continuous operation?

The card uses a passive heatsink design with no onboard fan, so it adds minimal noise and relies on server airflow for cooling.

Which server slots and form factor are required to install this LOM card?

It requires a compatible ThinkSystem server with a dedicated LOM slot; it does not fit standard PCIe add-in slots.
