Ethernet SFP28 and QSFP28 Interfaces
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 SFP28/QSFP28 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-5 and ConnectX-5 Ex adapter cards.
| IC Model | Supported PCIe Interface | Features |
|---|---|---|
| ConnectX-5 | PCIe Gen 3.0 (1.1 and 2.0 compatible) through x16 edge connectors | Link Rates: 2.5. 5.0 or 8.0GT/s. |
| ConnectX-5 Ex | PCIe Gen 3.0/4.0 (1.1 and 2.0 compatible) through x16 edge connectors | Link Rates: 2.5. 5.0, 8.0 or 16.0GT/s. |
LED Interface
There is one bi-color (yellow/green) I/O LED per port to indicate link status located on the adapter card.
Link Indications
State | LED Behavior |
|---|---|
| Beacon command for locating the card | Beacon command for locating the adapter card |
| 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 |
SMBus Interface
ConnectX-5 technology maintains support for manageability through a BMC. ConnectX-5 PCIe stand-up adapter can be connected to a BMC using MCTP over SMBus or MCTP over PCIe protocols as if it is a standard NVIDIA PCIe stand-up adapter. For configuring the adapter for the specific manageability solution in use by the server, please contact NVIDIA Support.
Voltage Regulators
The voltage regulator power is derived from the PCI Express edge connector 12V supply pins. These voltage supply pins feed on-board regulators that provide the necessary power to the various components on the card.
