PowerChute Network Shutdown in vMA?

Hi,

what are your experiences with  PowerChute Network Shutdown to ESXi 4.1 in vMA? It is not going as expected for me. It is Shuting Down VMs not doing Guest shut down!

In

Installation and Operation Instructions APC sais : "In order for PowerChute Network Shutdown to be able to shut down the virtual

machines (VM) on VMware ESXi or ESX, you need to configure a Guest Shutdown on

each VM." They mean to set default VMware Tools action on Shut Down set toGuest Shut Down? Or what? Becouse for me it still doing hard Shut Down.

Thanks.
