80 Appendix A
Operating environment
m Operating temperature: 10° to 35° C (50° to 95° F)
m Storage temperature: –40° to 47° C (–40° to 116.6° F)
m Relative humidity: 5% to 95% (noncondensing)
m Altitude: 0 to 3048 meters (0 to 10,000 feet)
Optical Drive Specifications
m Disk dimensions supported: 12 cm (4.7 in.)
Ethernet Specifications
m IEEE 802.3 compliant
m Maximum cable length: 100 meters (m)
m Connectors: RJ-45 for 10Base-T, 100Base-TX, and 1000Base-T
m Media, 10Base-T: Category 3 or higher UTP on 2 pairs up to 100 m
m Media, 100Base-TX: Category 5 UTP on 2 pairs up to 100 m
m Media, 1000Base-T: Category 5 and 6 UTP on 4 pairs up to 100 m
m Channel speeds: IEEE Auto Negotiation of 10Base-T, 100Base-TX, and 1000Base-T
FireWire Specifications
m Data transfer speed: 100, 200, up to 400, and up to 800 megabits per second (800 Mbps
available only on back-panel FireWire ports)
m FireWire 400 port (front panel) and two FireWire 800 ports (back panel)
Note: The FireWire 800 ports on your Xserve system transfer data from 800 Mbps devices
much faster than was possible before. These ports have 9-pin connectors, and are
compatible with original FireWire devices with 6-pin or 4-pin connectors.
With an appropriate cable, the new 9-pin ports work seamlessly with all FireWire devices.
Cables are available for connecting a 9-pin port to 4-pin, 6-pin, and 9-pin devices.
m Cables with the three types of FireWire connectors
FireWire 400 (6-pin) FireWire 400 (4-pin) FireWire 800 (9-pin)
