NVIDIA ConnectX-5 InfiniBand_Ethernet Socket Direct Adapter Cards User Manual

The network ports of the ConnectX®-5 adapter cards are compliant with the InfiniBand Architecture Specification, Release 1.3. InfiniBand traffic is transmitted through the cards' QSFP28 connectors.

The network ports of the ConnectX®-5 adapter card are compliant with the IEEE 802.3 Ethernet standards listed in Features and Benefits. Ethernet traffic is transmitted through the cards' QSFP28 connectors.

TThe ConnectX®-5 adapter card supports PCI Express Gen 3.0 (1.1 and 2.0 compatible) two PCIe x8 edge connectors; x8 edge connector on the adapter card and x8 edge connector on the auxiliary PCIe connection card accessible through the Slim Line-SAS cable. The device can be either a master initiating the PCI Express bus operations, or a slave responding to PCI bus operations.

  • PCIe Gen3.0 compliant, 2.0 and 1.1 compatible

  • 2.5, 5.0, or 8.0, or 16.0 GT/s link rate x8

  • Auto-negotiates to x8, x4, x2, or x1

  • Support for MSI/MSI-X mechanisms

There is one bi-color (yellow/green) I/O LED per port to indicate link status located on the adapter card.

Error

Blinks yellow at 4Hz until error is resolved. The reason for the error may be:

  • Failure of I2C access to the port

  • Over-current conditions of the port

Link Activity

Blinks green reflecting the link speed
