Maximum number
For the maximum adapters supported, see the PCI adapter placement topic collection for your
system.
For details about slot priorities and placement rules, see the PCI adapter placement topic collection for
your system.
Operating system or partition requirements
The adapter is supported under the following versions of the operating systems:
v AIX
– AIX 5.3, or later
v Linux
– Red Hat Enterprise Linux version 4
– Red Hat Enterprise Linux version 5
– SUSE Linux Enterprise Server 9, Service Pack 4, or later
– SUSE Linux Enterprise Server 10, Service Pack 1, or later
Note: 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 there are any prerequisites. To check for the
prerequisites, see IBM Prerequisite website (www-912.ibm.com/e_dir/eServerPrereq.nsf).
Adapter LED states
Green and yellow LEDs can be seen through openings in the mounting bracket of the adapter. Green
indicates firmware operation and yellow signifies port activity. Table 15 summarizes normal LED states.
There is a 1 Hz pause when the LED is off between each group of fast flashes (1, 2 or 3). Observe the
LED sequence for several seconds to ensure that you correctly identify the state.
Table 15. Normal LED states
Green LED Yellow LED State
On 1 fast flash 1 Gbps link rate - normal, link active
On 2 fast flashes 2 Gbps link rate - normal, link active
On 3 fast flashes 4 Gbps link rate - normal, link active
Power-On Self Test (POST) conditions and results are summarized in Table 16. These states can be used to
identify abnormal states or problems.
