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).

– Ubuntu Server 16.04, or later
v Supports PowerKVM and VIOS.
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 18 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.
