This will put those FastEthernet ports into an aggregated link, I'm 
pretty sure this will disable LACP.  Remove this and configure the same 
"link-aggregate key" on both interfaces instead.

Also, you'll want to configure the Juniper to full-duplex operation.

In general I'd advise you to try without LACP: configure everything hard
and let physical link failure detection do its job.

Here's one set of configuration statements on how that'd work:
