Drobo Pro Issues: Connection Interfaces are NOT Hot-Swappable

Story Leading into the Problem
Shortly after un-packaging my Drobo and hooking it up to my computer, I ran into this problem.  I'm so use to using USB devices that are hot-swappable, and so I just made the assumption that my Drobo Pro's 3 connection interfaces were hot-swappable too.

Not knowing that it was not hotswappable, I would switch the connection with Drobo powered on, from USB, to iSCSI, and even to Firewire 400.  At the time I didn't have my Firewire 800 card yet.

Anyways, at first, it appeared to be hot-swappable.  I was able to switch from USB to iSCSI, and to Firewire 400, but after a while of switching the connections back and forth, what started happening scared me a bit.  My Drobo stopped responding to any connections. It just wouldn't mount the drives in Windows anymore, even when connected on USB.

What made it worst was that this happened after I had transferred all my data from my internal computer drives into Drobo. I have no backups of the data anywhere else, and I had removed those drives from my computer, and inserted them into my Drobo.  Which means Drobo had formatted them, and added the additional space to the total usable space available via Drobo. All of that went smoothly, but when Drobo stopped responding, I assumed the worst had happened, that it lost all my data!

Debugging
1. I tried connecting, and disconnecting the cable.  It didn't work. 
2. I tried changing the interface, without turning Drobo off first.  That didn't work.
3. I searched the user manual for a solution, and searched online to see if anyone else had encountered this problem.  From the manual, and a few online postings in the Drobo Knowledgebase, I found out that what I had to do every time I wanted to switch the connection cable on Drobo Pro was to first shut it down using the Drobo Dashboard (safest way to shut it down), then switch the connection, then turn it back on.

Conclusion
1. Drobo Pro is not hot-swappable.  To change connections from USB, to iSCSI, to Firewire 800, you must first shut down Drobo. (See how to do it safely below)
2. Switch the connection cable
3. Power Drobo back on.

To Safely Shutdown Drobo
1. You should always use Drobo Dashboard to shutdown Drobo.  You can access the software shutdown command by clicking on the Tools > Shutdown.
2. You can use the switch at the back of your Drobo Pro alone, but you have to make sure that Drobo is not busy by waiting until the busy light no longer flashes, and is off.  The software shutdown is safest.  Doing this prevents data corruption.  Corruption happens when you shutdown Drobo while it is in the middle of writing data.
3. Power down your personal computer, which Gurantees that their won't be any data being written to your Drobo Pro from your computer.  Wait until your Drobo Pro goes into standby, and then switch it off using the power switch.

Notes
Obviously, don't power off your Drobo if any of the lights on Drobo indicate that it's working on something, like those tasks listed on the inner side of the front panel.  Use common sense.
