EATON EX 5 RT shutdown ESX 5.5 gracefully

Hello all,

I hope you'r doing well.

I have a little issue here.

I have a power supply, EATON EX 5 RT and I want to use it to shutdown gracefully my 3 ESX 5.5.

So I've installed the virtual machine Inteligent Power Manager (IPM) on one ESX and now I'm able to connect to it by web.

I've added my vcenter as a connector and I'am able to see the ESX.

I created a policy for each ESX to shut down when I have 30% of battery left.

But IPM does'nt shut the VMs... I guess I'm forgetting something.

I just go configuration policy,and I created a shutdown policy. Then I affected the policy to the ESX.

Can you help me please.
