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.
