I haven't seen this one. Customer has 2 cabinet OS500, PRI, svmi16e etc. svmi crashed today, when trying to reboot I get this:

FTPD File Transfer
Press ESC, X to exit
Sockets FTP Server v7.10
(misc info)

C close LISTEN
D dos shell
S status
X exit

Replaced card with same result. Moved card from 2nd to 1st cabinet with same result.

Thanks for your help.
