PS4000 doesn't see newly added secondary controller

We purchased a refurb type-8 controller for our PS4000 in our sandbox cluster.  After installation, it is not recognized.  "show enclosure" or "show controller" do not report it as being seen, and the GUI shows a red X over it.

We were going to install it and then upgrade the firmware since we're not sure what firmware it is on.  Is there a way to install the firmware directly onto the CF Card?

We looked for documentation on adding a new controller and any special steps we needed to take, but came up empty.

Any help is appreciated.
