Dual-Port 10Gbps Server Adapter

The Chelsio CC2-N320E-SR is a PCI Express network adapter with two SFP+ ports. It targets servers and workstations that require 10Gbps Ethernet connectivity. The card supports link speeds of 10, 100, 1000Mbps and 10Gbps. It suits administrators deploying high-throughput networking in rackmount or tower systems.

Throughput headroom at 10Gbps

Each SFP+ port delivers up to 10Gbps of Ethernet bandwidth. The adapter handles 10, 20, 100, 200 and 1000Mbps links for backward compatibility. It runs out of headroom when aggregate traffic exceeds the 10Gbps per-port limit. The dual-port design provides 20Gbps total potential throughput across both interfaces.

PCI Express slot and SFP+ modules

Installation requires an available PCI Express slot in the host system. Two SFP+ transceivers or direct-attach cables must be sourced separately to complete the links. The low-profile bracket fits standard and 1U chassis without blocking adjacent slots. The card frees up onboard ports for management or lower-speed traffic.

Questions about this item

Will the CC2-N320E-SR run at 1000 Mbps on my older Gigabit switch?

Yes, the adapter negotiates 10/20/100/200/1000 Mbps speeds so it will link at 1000 Mbps on a Gigabit switch.

How do I verify both SFP+ ports on the CC2-N320E-SR are active after installation?

Check the link LEDs on each port and confirm the OS sees two 10 Gbps Ethernet interfaces with valid IP configuration.

Does the CC2-N320E-SR include SFP+ transceivers or must I buy them separately?

The card ships without transceivers; you need to purchase compatible SFP+ modules for each port you intend to use.
