Interfaces
InfiniBand Interface
The network ports of the ConnectX®-6 adapter cards are compliant with the InfiniBand Architecture
Specification, Release 1.3. InfiniBand traffic is transmitted through the cards' QSFP56 connectors.
Ethernet QSFP56 Interfaces

The adapter card includes special circuits to protect from ESD shocks to the card/server when
plugging copper cables.
The network ports of the ConnectX-6 adapter card are compliant with the IEEE 802.3 Ethernet
standards listed in Features and
connectors on the adapter card.
PCI Express Interface
ConnectX®-6 adapter cards support PCI Express Gen 3.0/4.0 (1.1 and 2.0 compatible) through x8/x16
edge connectors. The device can be either a master initiating the PCI Express bus operations, or a
slave responding to PCI bus operations.
The following lists PCIe interface features:
• PCIe Gen 3.0 and 4.0 compliant, 2.0 and 1.1 compatible
• 2.5, 5.0, 8.0, or 16.0 GT/s link rate x16/x32
• Auto-negotiates to x32, x16, x8, x4, x2, or x1
• Support for MSI/MSI-X mechanisms
LED Interface

The adapter card includes special circuits to protect from ESD shocks to the card/server when
plugging copper cables.
There are two I/O LEDs per port:
• LED 1 and 2: Bi-color I/O LED which indicates link status. LED behavior is described below for
Ethernet and InfiniBand port configurations.
Benefits. Ethernet traffic is transmitted through the QSFP56
