SPCN

is used to control and monitor the status of power and cooling within the I/O drawer.
SPCN is a loop: Cabling starts from SPCN port 0 on the 570 to SPCN port 0 on the first I/O
drawer. The loop is closed, connecting the SPCN port 1 of the I/O drawer back to port 1 of the
570 system. If you have more than one I/O drawer, you continue the loop, connecting the next
drawer (or drawers) with the same rule.
