After you install PowerChute Network Shutdown by deploying the virtual appliance, VMware Tools shows an "Out-of-date" status.
PowerChute Network Shutdown v3.1 or above
The PowerChute Network Shutdown virtual appliance was created on ESXi. When deploying the OVA file to a later version of ESXi, the VMware Tools status displays the "Out-of-date" status.
Right-click on the PowerChute Network Shutdown appliance in vSphere Client.
Choose Guest - Install/Upgrade VMware Tools.
Choose Automatic Tools Upgrade.
