DHL delivered a big heavy box from BA today, with "0.5kg" printed as the weight on the shipping label.

Some observations:

It seems that one X3 is actually two 3U rack devices that make ~1TH/s each.  I had hoped for 3TH/s total as was alluded to earlier in the thread regarding "compensation", but I only received the two units.

They have six buttons on the front and a blank area that I guess was meant to be occupied by a large LCD.

When I plugged them in and checked the DHCP server on my router, they registered themselves as "android-a_16_digit_hex_number".

The units came with software version 1.0 installed, and when I did "check for updates", they updated themselves to 1.4, then 1.5, and finally 1.7.

The units detect each other on the LAN, and allow me to manage both units from a single web UI instance, which is convenient.

One of my units came clocked at 1100MHz, and the other at 1000MHz, which I can't seem to change.  I discovered a small "Hz" icon in the sidebar on the left of the web UI, which offers me the choice of 800, 1000, 1100, or 1200, but the buttons seem to have no effect.

They appear to be running OpenSSH server, but I'm not able to login via SSH.  The user:blackarrow login that works for the web UI does not work for ssh, nor does root:blackarrow.
