IBM I340-T4Product Intel Ethernet Quad Port Server Adapter 49Y4240

SKU CH-6PAV-HB2A8 MPN I340-T4Product

Quad-port Gigabit Ethernet card with four RJ-45 ports on a PCI Express 2.0 x4 interface for servers

  • Product typeGigabit Ethernet Card
  • Four RJ-45 ports deliver 10/100/1000Base-T connectivity
  • PCI Express 2.0 x4 host interface provides high throughput
  • Intel 82580 controller integrates four ports on one chip
  • Low-profile plug-in card fits 2.8" height server slots
  • Twisted-pair media support for standard copper cabling

Quad-Port Gigabit Ethernet Adapter

The IBM I340-T4Product adds four RJ-45 ports to a server through a single PCI Express 2.0 x4 slot. It is built around the Intel 82580 controller and targets administrators who need dense 10/100/1000Base-T connectivity in a low-profile plug-in card.

Sustained Multi-Port Throughput

Because all four ports share the PCIe 2.0 x4 host interface, the adapter can maintain aggregate throughput near the bus limit when multiple links are active simultaneously. The integrated multi-port controller keeps power dissipation low even when every port runs at 1000 Mbps for extended periods.

PCIe 2.0 x4 Bandwidth Ceiling

The x4 lane width caps total bidirectional bandwidth at the PCI Express 2.0 rate, so the four gigabit ports cannot exceed that combined ceiling. Systems limited to PCIe 1.0 or narrower slots will reduce the practical throughput available to each port.

Questions about this item

How much power does the I340-T4 draw when all four RJ-45 ports run at 1000Base-T all day?

The Intel 82580 controller is designed for lower power dissipation than previous multi-port designs, and the card uses a PCIe 2.0 x4 host interface.

What host slot and cabling must already be in the server for the I340-T4 to operate?

A free PCI Express 2.0 x4 slot and Cat 5e or better twisted-pair cables for the four RJ-45 ports are required.

Will the I340-T4 negotiate 10 and 100 Mb/s links on older switches while keeping all four ports active?

Yes, the adapter supports 10/100/1000Base-T on each of its four RJ-45 ports, so it will auto-negotiate down to legacy speeds.
