I just spent almost an hour on the phone with JTAC, and I explained the orphaned nature of the product and their support docs to their rep.
First, I needed to buy a support contract (20 minute Hold)
Then, I couldn't buy a contract, but I could pay a per incident fee to get a link to the firmware (15 minute Hold)
Then, I couldn't pay a per incedent fee, but I could get a contract exception (10 minute Hold)
Now, I can't buy a contract, pay an incident fee, get an exemption, or get the firmware from Juniper
All I can do is download from "somewhere" else...
I was trying to do this the "right" way, but that was not really the support I was hoping for!
