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 (www-912.ibm.com/e_dir/
eServerPrereq.nsf).
The adapter is supported on the following versions of the operating systems, depending on the system
you are using:
v Linux
– Red Hat Enterprise Linux Version 7, or later, with current maintenance updates available from Red
Hat.
– Red Hat Enterprise Linux Version 6.5, or later, with current maintenance updates available from Red
Hat.
– SUSE Linux Enterprise Server 11, Service Pack 3, or later, with current maintenance updates
available from SUSE.
– SUSE Linux Enterprise Server Version 12, or later
– Linux Ubuntu 15.04, or later
– The latest version of the device driver or iprutils can be downloaded from the IBM Service and
Productivity Tools website(http://www14.software.ibm.com/webapp/set2/sas/f/lopdiags/
home.html).
v PowerKVM
– IBM PowerKVM 2.1.1, 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 13 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.
