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.
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.
Auto Negotiation to: x16, x8, x4, x2 or
x1.
Support for MSI/MSI-X mechanisms.
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.
Auto Negotiation to: x16, x8, x4, x2 or
x1.
Support for MSI/MSI-X mechanisms.
LED Interface
There are two I/O LEDs, LED0 and LED1, per port to indicate speed and link status. LED0 is a bicolor
(yellow and green) LED and LED1 is a single color (green) LED.
