  ^^^^^^^^^^^^^^
where did this prompt come from? ie: what does "us-head-bcn" mean?
is it always within []s (square brackets)?  always end with $ (dollar
sign)?

no prompt for a password, because it is the "manager" account.  right?

btw, when i say "always", I mean at that privilege level and with all
bay devices capable of cmd-line...or at least those we hope to collect.

the prompt is "box"?  not us-head-bcn# or bcc#?

I should have asked explicity; what does the exit from 'box#' back to your
host look like?
