Each TPM is connected to both operating and protection I/O modules in the
shelf in a 1:1, 1:2, or 1:3 configuration. If a failure is detected in one of the
operating I/O modules, the active MXC via the TC module in the TPU switches
the traffic from the active I/O module to the protection module.
The following figures show several options for installing TPUs with the
XDM-300 shelf.
