= Switching Bluefield-2 from DPU mode to NIC mode
Use the following procedure to switch Bluefield-2 from data processing units (DPU) mode to network interface controller (NIC) mode.
Use the following procedure to switch Bluefield-2 from data processing units (DPU) mode to network interface controller (NIC) mode.
[IMPORTANT]
====
Currently, only switching Bluefield-2 from DPU to NIC mode is supported. Switching from NIC mode to DPU mode is unsupported.
