Specifications

FireWire Ports

The Power Mac G5 computer has one FireWire 800 port based on IEEE 1394b and two FireWire 400 IEEE 1394a

ports. Each FireWire port

●

supports booting the system from a mass storage device

●

supports target disk mode

●

provides bus repeating capability as long as the computer is connected to AC power

●

provides power for FireWire devices both in run and sleep mode (useful for charging the iPod)

The three FireWire ports share a single power supply that can provide up to 15 watts total. The three ports are

all on the same FireWire bus and can connect to up 62 other FireWire devices.

The FireWire hardware and software provided with the Power Mac G5 computer are capable of all asynchronous

and isochronous transfers defined by IEEE standards 1394a and 1394b.

Note: FireWire cables are not included with this product and must be purchased independently,

if required.

the other sources listed in FireWire Interface (page 67).

FireWire 800 Connector

The FireWire 800 port on the Power Mac G5 computer is based on IEEE 1394b and enables a 800 Mbps transfer

rate. FireWire 800 uses a 9-pin connector and is backwards compatible with original 1394a (FireWire 400)

devices with 6-pin or 4-pin connectors. With the appropriate cable, the 9-pin port works seamlessly with legacy

FireWire devices. Cables are available to go from both 6-pin and 4-pin connectors to a 9-pin, and 9-pin to 9-pin.
