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

Table 1. Adapter LED and descriptions
LED Light Description
Activity/Link Green Good link, no activity
Flashing Orange Transmit activity
Off No link*
Adapter card status Red Not initialized**
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 that is required to support the new feature and that you determine whether any prerequisites must be met for this feature and attaching devices. To check for the prerequisites, see IBM Prerequisite website.

The adapter is supported on the following versions of the operating systems, depending on the system you are using:
  • AIX®
    • AIX Version 6.1, or later
    • AIX Version 5.3, or later
  • Linux
    • Red Hat Enterprise Linux Version 7, or later, with current maintenance updates available from Red Hat.
    • Red Hat Enterprise Linux Version 6, or later
    • Red Hat Enterprise Linux Version 5.6, or later
    • SUSE Linux Enterprise Server 11, Service Pack 1, or later, with current maintenance updates available from SUSE.
    • For support details, see the Linux Alert website.
    • The latest version of the device driver or iprutils can be downloaded from the IBM Service and Productivity Tools website.
AIX host bus adapter (HBA) and Ethernet drivers are contained in the following filesets:
  • devices.ethernet.ct3
  • devices.ethernet.ct3.rte //HBA
  • devices.ethernet.ct3.cdli //ENT

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.

If you are running the total diagnostics package you need a wrap plug for the multimode fiber connector used for the adapter. To connect to a network, you need a shortwave (850 nm) 50/62.5 micron multimode fiber network attachment.

The following tables indicates the allowable cable lengths from the adapter to the gigabit Ethernet switch, including patch cables:

Table 2. Cable information
Fiber cable type Connector type Minimum modal bandwidth at 850 nm (MHz x km) Operating range in meters
62.5 µm MMF LC 160 2 to 26 (6.56 ft to 85.30 ft)
200 2 to 33 (6.56 ft to 108.26 ft)
50 µm MMF LC 400 2 to 66 (6.56 ft to 216.53 ft)
500 2 to 82 (6.56 ft to 269.02 ft)
2000 2 to 300 (6.56 ft to 984.25 ft)

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:

  1. If necessary, log in as root user.
  2. At the command line, type: lsdev -Cs pci
  3. 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.

Connecting to an Ethernet network

This section explains how to connect the adapter to the multimode fiber network. Refer to your local procedures for information about connecting the adapter to your Ethernet network.

Note: Only one type of network can be attached to the adapter at one time.

To connect the adapter to a multimode fiber network, do the following steps:

  1. Insert the male fiber LC connector of the fiber cable into the adapter LC connector.
  2. Insert the male fiber LC connector of the other end of the cable into the network switch.
Notes:
  • The adapter requires an 850 nm multimode fiber optic cable. See Table 2.
  • If your switch has an SC receptacle, you need an LC-SC converter cable.
  • It is necessary to configure an IP network interface to enable the adapter to detect a link and to illuminate the link LED.
