Table 3 describes the face plate connectors on the RTM:
Reset button
The RTM face plate includes a reset button, which causes the RTM MMC to issue a cold reset to
the CPM’s IPMC over the IPMB-L. The IPMC then resets the CPM and the RTM payload.
The reset switch is a recessed button. To push it, use a pen, stylus, or other small pointed object.
