Apple G5 manual Maximizing Ethernet Performance, Locating Your Product Serial Number

Installing Classic Support and Other Applications

Use the “Additional Software & Apple Hardware Test” to install Classic support and additional applications that were not included on Mac OS X install disc 1. Install Classic support if you want to use Mac OS 9 applications with your computer.

Follow these steps to install Classic support or the additional bundled applications:

1Back up your essential files, if possible.

2Insert the “Additional Software & Apple Hardware Test” disc that came with your computer.

3Double-click “Install Extra Software.”

4Follow the onscreen instructions.

5After selecting the destination disk for installation, continue following the onscreen instructions for a basic installation or click “Customize” to choose the applications you want to install.

Maximizing Ethernet Performance

Your computer performs best when the Ethernet port to which it is connected is set to auto-negotiate. Ask your network administrator to verify this setting.

Important: If you experience connection problems on your network, make sure your network switch is set to auto-negotiate, if possible. If a switch’s port is not auto- negotiating, your computer detects the appropriate speed but defaults to half-duplex mode. If the switch’s port at the other end of the link is configured for full-duplex mode, a large number of late events can occur on the link. If it isn’t possible to set the switch to auto-negotiate, then set the switch’s port to half-duplex. For more information, see the documentation that came with the Ethernet switch.

Note: If you connect your computer directly to a configurable Ethernet switch, have your network administrator disable spanning tree on that port. Otherwise your computer may duplicate the AppleTalk address of another computer on the same network and both network connections may become unreliable.

Locating Your Product Serial Number

The serial number of your Power Mac G5 is on the configuration label, which is located inside the side panel, directly below the air deflector. System Profiler also shows the serial number. Open System Profiler (in Applications/Utilities) and click the System Profile tab.
