mouse,
have you already looked through this document?
http://archives.retrobridge.org/sun/system-handbook/3.4/collections/TECHNICALINSTRUCTIONSURE/1-71-1018648.1-1.html
resetting the SP to defaults only wipes out user and network settings so it
should not affect operation of the box itself. you can then create new user
credential and ssh in and play around to try to figure out exactly what
management and troubleshooting functions the sp is responsible for.
cheers
