1 Introduction
The Server Expansion Unit is a member of the HP business-critical computing platform family: a mid-range,
mid-volume I/O expansion cabinet. It provides additional I/O performance with the inclusion of 16 PCI-X
slots, two additional core I/O cards, four more hard disk drives, and two removable media drives. There are
not any cell boards installed in the Server Expansion Unit. The Server Expansion Unit connects to both the
HP 9000 rp8400 server and the HP Integrity rx8620 server providing additional I/O slots to these servers.
