Maximum number
For the maximum adapters supported, see the PCI adapter placement topic collection for your
system.
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 there are any prerequisites for this feature and attaching devices.
To check for the prerequisites, see IBM Prerequisite website (www-912.ibm.com/e_dir/eServerPrereq.nsf).
The adapter is supported on the following versions of the operating systems:
v AIX
– AIX 7.1, or later
– AIX 6.1, or later
v Linux
– Red Hat Enterprise Linux
– SUSE Linux Enterprise Server
– For support details, see the Linux Alert website (www14.software.ibm.com/webapp/set2/sas/f/
lopdiags/info/LinuxAlerts.htm)
v IBM i
– IBM i 7.1, or later
– IBM i 6.1, or later
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 10 summarizes normal LED states.
A 1 Hz pause occurs when the LED is off between each group of fast flashes (2, 3 or 4). Observe the LED
sequence for several seconds to ensure that you correctly identify the state.
Table 10. Normal LED states
Green LED Yellow LED State
On 2 fast flashes 4 Gbps link rate: normal, link active
On 3 fast flashes 8 Gbps link rate: normal, link active
On 4 fast flashes 16 Gbps link rate: normal, link active
Power-on-self-test (POST) conditions and results are summarized in Table 11 on page 26. These states can
be used to identify abnormal states or problems.
