Additional I/O resources can be obtained by adding the HP Server Expansion Unit (SEU). The SEU is an
add on chassis containing I/O resources that complement the I/O and partitioning capabilities within the
HP 9000 rp8420 Server. The SEU mirrors the I/O resources embedded within the HP 9000 rp8420
Server chassis, adding 16 PCI X I/O card slots, 4 disk bays, 2 removable media slots, and enabling 2
additional hard partitions in the server.
The SEU must be installed in the same cabinet and directly above the host HP 9000 rp8420 Server for
factory racked installations. For field installations, the SEU can be installed in an adjacent rack at the
same height as the server if there is space limitations. The preferred installation is directly above the host
server in the same rack . Please refer to therp84xx/rx86xx Server Expansion Unit section in this guide for
more specific details.
The following table summarizes the I/O configuration rules when an SEU is configured with the HP 9000
rp8420 Server.
