Can't Access Boot Menu - Ultra 6

I realize there are other threads about this issue but mine is a bit diiferent.

I just replaced memory in both my Ultra 6s. The steps were:

Ultra Unit A

Removed disks

Installed new memory

Ran memory test (passed)

Replaced disks

Done

Ultra Unit B

Removed Disks

Installed new memory

Couldn't access Boot Menu to perform a memory test.

Swapped memory from Unit A and Unit B (with "good" memory)

Couldn't access Boot Menu

Placed blank disk in Unit B and powered up.

Couldn't access Boot Menu

Disk Passed

Started to perform Factory Reset on Unit B

I pulled the plug when I saw "Awaiting RAIDar"

So it seems Unit B is working fine other than I can't access the Boot Menu.

I would imagine the reset button isn't functioning on Unit B or is it possibly caused by something else?

Here's my MAIN question:

What should I expect when I put the original disks in Unit B?

I noticed that Unit B was assigned a new IP address so I am somewhat uncertain about what to expect.
