The 80333 has an auxiliary power receptacle (J1A1, see

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
