The HP SEU mirrors the I/O resources embedded within the Integrity rx8620-32 Server chassis, both 
physically and electrically. The high-speed connection between the Integrity rx8620-32 Server and the 
SEU is provided through a remote I/O (RIO) cable with 4 GB/s bandwidth. The RIO cable mounts 
directly to the system backplane board in the Integrity rx8620-32 Server and to the I/O backplane 
board in the SEU.
