68-pin connector 10/100 BASE-T Ethernet using the HME adapter IEC mains input connector 1 Gbit/s Ethernet can be used with the optional Sun X1141A Ethernet card. USB is not officially supported, but various USB boards for PCs have been known to work with Linux and Solaris. Power consumption According to the hardware specifications on the Sun web site, the maximum power consumption is 380 W. The components list lists the power supply (Sun part number 300-1357) as a Sony 670 W 12A power supply. A well fitted system (2x450MHz, 2GB memory, Elite3D graphics, one disk) draws about 200 watts when idle. Reducing Power Remove 2nd video card and 2nd CPU. Construction quality The Ultra 60 is a well built workstation. It does not use cheap mass-produced commodity PC parts like other Ultra workstations such as the Ultra 5 and Ultra 10. It is well cooled, suffering none of the problems of overheating like Sun's previous quad processor machine, the SPARCstation 20. Support The Ultra 60 is no longer sold new, but it is Sun's policy to support hardware for 5 years from the date of last shipment, so the Ultra 60 was officially supported until October 2007. In addition to official support, knowledgeable people (often Sun employees) are regular visitors to the comp.unix.solaris, comp.sys.sun.hardware and comp.sys.sun.admin Usenet newsgroups.
