Green circuit board with four RJ45 ports and PCIe x4 edge connector

Axiom

Axiom 665240-B21-AX quad port RJ45 PCIe 2.1 x4 network card

SKU CH-CWAG-GZ4DD MPN 665240-B21-AX

Quad-port RJ45 PCIe 2.1 x4 card adds four gigabit Ethernet links to servers

  • Four gigabit RJ-45 ports expand server connectivity
  • PCI Express 2.1 x4 host interface supports high throughput
  • Low-profile 5.9" x 2.2" form factor fits dense chassis
  • Twisted-pair media support simplifies copper cabling
  • Three-year limited warranty covers hardware defects

Quad-port server NIC

The Axiom 665240-B21-AX provides four RJ-45 ports over a PCI Express 2.1 x4 host interface. It supports 10/100/1000Base-T on twisted-pair media and uses a plug-in card form factor. The card is designed for server devices that need multiple copper connections in a single slot.

Sustained throughput on four ports

Each port handles 10, 100, or 1000 Mbps links with auto-negotiation. The x4 lane interface supplies enough bandwidth to keep all four ports active at gigabit line rate without head-of-line blocking. The low-profile dimensions of 5.9 by 2.2 inches fit standard server chassis airflow paths.

Low-profile plug-in installation

The bracket matches a standard low-profile slot so no riser or adapter is required. Installers should verify the server backplane has a physical x4 or longer slot; some older systems only expose x1 electrical connections. The 3.84 oz weight adds negligible stress to the motherboard. Buyers who need fibre uplinks or more than four copper ports cannot use this card.

Questions about this item

How much power does the PCIe 2.1 x4 quad-port card draw when running continuously?

The adapter uses a PCI Express 2.1 x4 host interface and four 10/100/1000Base-T RJ-45 ports; total power draw depends on the server slot limit and cable length.

What server slot and bracket height does the 665240-B21-AX need to install?

It requires an open PCI Express 2.1 x4 slot and fits a standard 5.9 inch height bracket with a 0.6 inch profile.

Will the card negotiate 10/100/1000 speeds on older Cat 5e cabling already in the rack?

Yes, the four twisted-pair ports support 10, 100 and 1000 Mbps auto-negotiation on existing Cat 5e or better links.
