10 Gigabit Ethernet-CX4 PCI Express Adapter (FC 5732; CCIN 5732)

Learn about the features, operating system requirements, and installation procedures for the 5732 adapter.

Overview

The 10 Gigabit Ethernet-CX4 PCI Express® Adapter is a low-profile, high performance CX4 copper network interface controller (NIC). The product conforms to the IEEE, 802.3ae 10GBASE-CX specification for Ethernet transmission. 10GBase-CX4 uses the XAUI (10 Gigabit attachment unit interface) specified in 802.3ae, and the 4X connector that is used for InfiniBand technology. The adapter is used to connect servers or switches over short distances of up to 15 meters.

The following figure shows the adapter.

The LED on the adapter provides information about the operation status of the adapter.

Table 1. Adapter LED
LED	Light	Description
Activity/Link	Green	Good link, no activity
	Flashing Orange	Transmit activity
	Off	No link^*
Adapter card status	Red	Not initialized^**
Adapter card status	Off	Initialized
^The absence of a link could be the result of a defective cable, a defective connector, or a configuration mismatch. ^*The adapter has not been initialized by the operating system. During such time, the following conditions are true: If no cable is connected, the Green LED is ON. If cable is connected and the LINK is sensed, the Green LED is OFF.

Operating system or partition requirements

If you are installing a new feature, ensure that you have the software required to support the new feature and that you determine if there are any existing prerequisites. To do this, use the IBM® Prerequisite Web site at http://www-912.ibm.com/e_dir/eServerPrereq.nsf Link outside information center .

The 10 Gigabit Ethernet-CX4 PCI Express Adapter is supported on the following versions of the AIX® and operating systems:

Preparing for installation

If you are installing your operating system at this time, install your adapter before you install the operating system. If you are installing only the device driver for this adapter, install your device driver software before you install the adapter. Ensure that your operating system supports this adapter before you install it. See Operating system or partition requirements.

Installing the AIX device driver software

To install device driver software, follow the steps in Installing the AIX device driver software.

Installing the adapter

For general instructions on how to install a PCI adapter, see the Installing PCI adapters topic. Return here to verify the adapter installation.

Verifying the adapter installation

To verify that your system recognizes the PCI adapter, do the following steps:

If necessary, log in as root user.
At the command line, type: lsdev -Cs pci
Press Enter.

A list of PCI devices is displayed. If the adapter is installed correctly, the status of available for each port indicates that the adapter is installed and ready to use. If a message indicates that any of the ports are defined instead of available, shut down your server and verify that the adapter was installed correctly.
