Cables
Cables are the responsibility of the customer.
Use multimode fiber optic cables with shortwave lasers that adhere to the following
specifications:
v OM3: Multimode 50/125 micron fiber, 2000 MHz x km bandwidth
v OM2: Multimode 50/125 micron fiber, 500 MHz x km bandwidth
v OM1: Multimode 62.5/125 micron fiber, 200 MHz x km bandwidth
Because core sizes are different, OM1 cables can only be connected to other OM1 cables. For best
results, OM2 cables should not be connected to OM3 cables. However, if an OM2 cable is
connected to an OM3 cable, the characteristics of the OM2 cable apply to the entire length of the
cables. The following table shows the supported distances for the different fiber optic cable types
at different link speeds.

Maximum number
For details about the maximum number of adapters that are supported, see PCIe adapter
placement rules and slot priorities(http://www.ibm.com/support/knowledgecenter/POWER8/
p8eab/p8eab_mtm_pciplacement.htm) and select the system you are working on.
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, depending on the system
you are using:
