Product Overview of the IBM 49Y4240 Ethernet

In today's world, networking has become an essential component of any computer system, and having a reliable and efficient network adapter is crucial for smooth data transmission. The IBM 49Y4240 PCI Express Gigabit Ethernet Quad Port Network Adapter is a high-performance network adapter that offers fast data transfer rates, reliability, and flexibility. In this article, we will delve deeper into the technical specifications and features of the 49Y4240 IBM PCI Express Gigabit Ethernet Quad Port Network Adapter.

PCI Express Gigabit Ethernet Quad Port Network Adapter

The IBM 49Y4240 is a PCI Express Gigabit Ethernet Quad Port Network Adapter that is designed to be used in servers and workstations. The adapter features four independent Gigabit Ethernet ports that provide high-speed data transfer rates of up to 1000 Mbps per port, allowing for fast and efficient data transfer.

PCI Express is a high-speed serial computer expansion bus standard that enables fast data transfer rates between the adapter and the computer's motherboard. The IBM 49Y4240 utilizes the PCI Express 2.0 x4 interface, which offers a maximum theoretical bandwidth of 20 Gbps.


The IBM 49Y4240 PCI Express Gigabit Ethernet Quad Port Network Adapter is compatible with a wide range of operating systems, including Windows, Linux, and VMware. The adapter is also compatible with IBM System x servers and workstations, including the IBM System x3250 M3, x3400 M3, x3550 M3, x3650 M3, and x3850 X5. The adapter is designed to be hot-swappable, meaning that it can be installed or removed without shutting down the computer. This feature allows for easy maintenance and upgrades, without disrupting the operation of the computer.


The IBM 49Y4240 PCI Express Gigabit Ethernet Quad Port Network Adapter offers several features that make it a reliable and efficient network adapter.

  • Support for Jumbo Frames

Jumbo Frames are a feature of Ethernet networks that allow for the transmission of larger packets of data than the standard Ethernet frame size. The IBM 49Y4240 supports Jumbo Frames, which can improve network performance by reducing the overhead associated with transmitting larger packets of data.

  • Load Balancing

The adapter supports load balancing, which allows for the distribution of network traffic across multiple Ethernet ports. This feature can improve network performance by reducing congestion on individual ports.

  • VLAN Support

The IBM 49Y4240 supports Virtual Local Area Network (VLAN) tagging, which allows for the segmentation of a network into multiple virtual networks. This feature can improve network security and performance by isolating traffic between different virtual networks.

  • Network Fault Tolerance

The adapter supports Network Fault Tolerance (NFT), which allows for the redundancy of network connections. In the event of a network connection failure, the adapter can automatically switch to a backup connection, ensuring that network traffic continues to flow without interruption.

  • Ethernet Flow Control

The IBM 49Y4240 supports Ethernet Flow Control, which allows for the management of network traffic. The feature enables the adapter to send pause frames to the network switch, requesting that the switch temporarily stop sending data. This feature can help prevent packet loss and improve network performance.

Overall, the IBM 49Y4240 PCI Express Gigabit Ethernet Quad Port Network Adapter is a reliable and efficient network adapter that offers high-speed data transfer rates, compatibility with various operating systems, and several features that enhance network performance and reliability. With its support for Jumbo Frames, Load Balancing, VLAN tagging, Network Fault Tolerance, and Ethernet Flow Control, this adapter is an ideal solution for servers and workstations that require high-performance network connectivity.
