RIO-2 Cabling
I/O drawers are connected to the system through remote I/O (RIO-2) cable loops. The cable loops are
connected to ports located on the rear of the system. The RIO-2 cables are connected in loops so that the
system has two paths to each I/O drawer.
Up to two I/O drawers can be connected to a system using one RIO-2 loop. For cabling examples, see the
following illustrations.
