PMC I/O Voltage Configuration
The onboard PMC sites may be configured to support 3.3V or 5.0V I/O PMC modules. To
support 3.3V or 5.0V I/O PMC modules, both PMC I/O keying pins must be installed in the
holes. If both keying pins are not in the same location or if the keying pins are not installed, the
PMC sites will not function. Note that setting the PMC I/O voltage to 5.0V forces the PMC sites
to operate in PCI mode instead of PCI-X mode. The default factory configuration is for 3.3V
PMC I/O voltage.

RTM SEEPROM Address Switch (S1)
A 4-position SMT configuration switch is located on the RTM to set the device address of the
RTM serial EEPROM device. The switch settings are defined in the following table.
