Expansion cards and devices

If you add a PCI expansion card or an internal SCSI device to your server, make sure the component doesn’t exceed its maximum power allowance from the different voltage sources. No single PCI card should exceed the 25 watt limit of the PCI Revision 2.1 specification. Follow these guidelines.

Network Server	Voltage	Current	Total power

500 model	+3.3 V	10.0 A	Not to exceed 50.0
			watts in any combination
	+5 V	10.0 A
	+12 V	2.0 A
700 model	+3.3 V	18.0 A	Not to exceed 90.0
			watts in any combination
	+5 V	18.0 A
	+12 V	2.0 A

For SCSI devices, the average (thermal) power consumption per drive bay is

1.1amps at +5 volts and 1.3 amps at +12 volts. Apple recommends that drives be configured for spin-up on command or delay.
