Data Interfaces
The data interfaces use QSFP28/56/DD connectors. The full list of interfaces per system is provided in Speed and Switching Capabilities.As detailed in the following table, for additional data interfaces, each QSFP28/56/DD port can be connected with a QSFP28/56/DD cable or connector through NVIDIA QSFP28/56/DD to SFP (Dynamix QSA™) adapters, hybrid, or split cables*.

*In the SN4600 and SN4700 systems, when interconnecting switch-to-switch and switch-to-NIC in 50GbE, 100GbE, 200GbE, and 400GbE-based PAM4 speeds, the supported length of PAM4 passive copper and breakout cables is up to 2.5m.
The "Maximum High Power Support" column in the following table specifies each system's maximum power capabilities per port:
Model Family | Ports | Maximum High Power Support |
SN4600 | All ports | 5W |
49-50, 53-54, 57-58, 61-62 | 6.5W | |
SN4600C | 1-48 | 3.5W |
49-64 | 5W | |
SN4700 | All ports | 12W |
