Trying to put a BlueField-2 into BlueField-X mode with power cycle

Used sudo mlxconfig -d /dev/mst/mt41686_pciconf0 s PCI_DOWNSTREAM_PORT_OWNER[4]=0xF
to set up X mode on a BlueField 2. Then

the DOCA manual says " Power cycle is required for configuration to take effect. To power cycle the host run:

host# ipmitool power cycle  

however when I run:
/usr/share/bash-completion/completions/ipmitool power cycle
sudo /usr/share/bash-completion/completions/ipmitool power cycle

nothing seems to happen. Can I just power cycle the entire server instead?

using a separately controlled power cycle worked with the Bluefield going into X-mode.
