The CPU in the IP Switch Control Board is a 166MHz Pentium processor and
runs a variant of BSD UNIX as its operating system. For this reason, the GRF
administrator is assumed to be proficient in UNIX.
The IP Switch Control Board is used to install, boot, and configure the router
and its media adapters.
It is also used for the logging of messages, the dumping of memory and
status, and to perform diagnostic checking of both the GRF and the media
adapters.
