IQ80332 I/O Processor

Getting Started

2.2.2 Power Requirements

The 80332 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 80332 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 80332 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.
