Manufacturer Contact Info:,

This 4-speed NBASE-T™ PCIe network card offers an inexpensive network upgrade solution, providing access to your network at multiple speeds up to 5G, using your existing Cat5e copper cabling.

Cost-effective Multi-Gigabit Ethernet

Fully compliant with 2.5GBASE-T, 5GBASE-T, and NBASE-T (Draft IEEE802.3bz) specifications, the PCIe NIC offers a cost-effective and versatile networking solution. It provides additional bandwidth at multiple speeds, to meet your network needs without the expense of overhauling your existing cable infrastructure.

Advanced technology for optimal performance

The featured NBASE-T technology and multi-gigabit speeds support Cisco® campus switches, including Catalyst 4500E, 3850 and 3560-CX. The Marvell® 88E2010 chipset is optimized for achieving 2.5 and 5G rates over your existing Cat5e copper cable setup without upgrading to the more expensive Cat6A cabling required for 10Gbps speeds.

Operating efficiency and flexible use

The Tehuti Networks™ TN4010 chipset, compliant with IEEE 802.3az, ensures peak operating efficiency with reduced power consumption. The network card also supports 9K jumbo frames, 802.1q VLAN tagging and is backward compatible with 1000BASE-T. For additional versatility, the controller card is equipped with a standard-profile bracket and includes a low-profile bracket for installation in small form-factor computers.

The ST5GPEXNB is backed by a 2-year warranty.
