Slot requirement
For more information about slot priorities, maximums, and placement rules, see PCIe adapter
placement rules and slot priorities and select the system that you are working on.
Thermal requirement
If you have a 5105-22A 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.
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 you use the HDR 100 Gb
splitter cables.
