DELL JM42W X520-T2 PCI Express 2.0 X8 10 Gbps dual-port network card

Dell JM42W X520-T2 10 Gbps dual-port adapter

This Dell network adapter provides two 10 Gbps Ethernet ports on a single low-profile card. It connects through a PCI Express 2.0 x8 slot and supports TCP/IP, UDP/IP and IPSEC protocols. The JM42W model is designed for server and workstation environments requiring wired 10 Gigabit connectivity.

Suited for servers adding 10 GbE links

IT administrators upgrading rackmount or tower servers to 10 Gigabit Ethernet will find this dual-port card a direct fit. The low-profile bracket allows installation in slim chassis where full-height cards cannot be used. Systems limited to PCI Express 1.0 slots or lacking an x8 electrical connection cannot use this adapter at its rated speed. Buyers needing fibre connections or more than two ports must select a different adapter.

PCI Express 2.0 x8 interface determines

The card requires a motherboard slot wired for at least PCI Express 2.0 with eight lanes to deliver the full 10 Gbps per port. Slots running at x4 or x1 electrical width will reduce available bandwidth. Verify the target system provides an x8 slot before purchase.
