InfiniBand Interface
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.
Ethernet QSFP28 Interface
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.
PCI Express Interface
The ConnectX®-5 adapter card supports PCI Express Gen 3.0/4.0 (1.1 and 2.0 compatible) through an x16 edge connector. 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 Gen4.0 and 3.0 compliant, 2.0 and 1.1 compatible
- 2.5, 5.0, or 8.0, or 16.0 GT/s link rate x16
- Auto-negotiates to x16, x8, x4, x2, or x1
- Support for MSI/MSI-X mechanisms
LED Interface
There is one bi-color (yellow/green) I/O LED per port to indicate link status located on the adapter card.
Physical and Logical Link Indications - Ethernet Mode:
State | LED Behavior |
Beacon command for locating the card | Blinks yellow at 1Hz |
Error | Blinks yellow at 4Hz until error is resolved. The reason for the error may be:
|
Link Activity | Blinks green reflecting the link speed |
Link Up | Constant green light |
