Set PSU node to Maintenance mode using PowerShell command?

Product: PowerShell Universal
Version: 4.3.2

How do I set PSU node to Maintenance mode using a PowerShell command or a PSU API? I want to automate rebooting of the nodes, so I assume the prudent thing to do would be to put it in maintenance mode first.
Thanks.

Set-PSUComputer provides a -Maintenance flag that you can use.

Get-PSUComputer | Where-Object Name -eq 'Server123' | Set-PSUComputer -Maintenance $true

Thank you
