Power Requirements
The 80333 requires a 3.3 V supply coming through the PCI Express primary connector. Plug the
board into a desktop with a PCI Express slot.
The 80333 has an auxiliary power receptacle (J1A1, see
Section 3.9.4, “Connector Summary”
) that
is used to power the secondary PCI-X slot. This connector is compatible with a standard ATX hard
drive power connector.
Caution:
Before connecting power to the entire system, verify that the auxiliary system power to the
secondary PCI-X slot and the main power to the 80333 are both connected. Both power rails should
come up at the same time. When there is not a card plugged into the secondary PCI-X slot, then the
auxiliary power can be left unconnected.
