Landing servers - agent required?

I am running PMP on a Windows server and I want to use another Windows server as an SSH jump box/landing server to connect to network devices.

In this configuration, how does the PMP server launch the connection on the intermediate server so that it can display the SSH output? Is the agent required?

I'm reading the documentation for the feature and I don't see anything mentioned. Is it assumed that the intermediate/launch server must support SSH natively (i.e. runs *nix)?
