V(I/O)
3.3 V
5 V
Not all V(I/O) planes need to be configured for the same level. It is valid to have some V(I/O)
planes set to 3.3 V while others are set to 5 V.
M66EN jumper settings required for different V(I/O) levels on each V(I/O) plane.
Warning: It is critical that each V(I/O) plane does not have both its 3.3 V and 5 V shunts loaded
simultaneously. Doing so causes permanent damage to the midplane and could pose a fire hazard.
