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 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.

The adapter card includes special circuits to protect from ESD shocks to the card/server when
plugging copper cables.

PCI Express Interface

The table below describes the supported PCIe interface in ConnectX-6 adapter cards.
Supported PCIe Interface
PCIe Gen 3.0/4.0 (1.1 and 3.0 compatible) through x16
edge connectors

LED Interface

There are two I/O LEDs, LED0 and LED1, per port to indicate speed and link status. LED0 is bicolor
(yellow and green) LED and LED1 is a single color (green) LED.
Link Indications
LED and State
1Hz blinking Yellow
Benefits. Ethernet traffic is transmitted through the QSFP56
Beacon command for locating the adapter card
