Wrap plug FRU number
Note: The wrap plug is included with the card, and can also be purchased from IBM.
I/O bus architecture
PCIe2.0 x8
Slot requirement
For more information about slot priorities, maximums, and placement rules, see PCIe adapter
placement rules and slot priorities (
p9eab/p9eab_mtm_pciplacement.htm) and select the system that you are working on.
3.3 V and 12.0 V
Form factor
Short, low-profile
For information about the cables, see "Cables"
Attributes provided
v NPIV capability is supported through VIOS.
v Requires a PCI Express generation-2 x8 slot for all four ports to operate at full speed.
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.
Table 58. Supported distances for multimode fiber optic cables
2.125 Gbps
4.25 Gbps
8.5 Gbps
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 operating system and partition requirements, see one of the following links:
