Slot requirement
For details about slot priorities, maximums, and placement rules, see PCIe adapter placement rules
and slot priorities (http://www.ibm.com/support/knowledgecenter/POWER9/p9eab/
p9eab_mtm_pciplacement.htm) and select the system you are working on.
Thermal requirement
If you have an 8335-GTG, 8335-GTH, or 8335-GTX system, you might be required to set the thermal
mode of the system to a setting other than the default setting, depending on your system, adapter,
and cable type. For details, see Determining and setting the thermal mode for an 8335-GTG, 8335-
GTH, or 8335-GTX system.
Cables
For HDR 100 Gb, IBM offers either Direct Attach Copper (DAC) cables up to 2 M or Active Optical
Cables (AOC) up to 100 M. QSFP56 based transceivers are included on each end of these cables.
Cable matrix
The EDR cables that are listed in the table support connecting an HDR 100 Gb adapter to EDR 100 Gb
or HDR 200 Gb InfiniBand switches. The HDR 100 Gb splitter cables that are listed in the table
support connecting to an HDR 100 Gb adapter to an HDR 200 Gb switch.
Note: An HDR 200 Gb switch port must be in split-mode configuration when using the HDR 100 Gb
splitter cables.
