Serial PortYou can connect a management console or a computer running terminal emulationsoftware to the Xserve serial port, and then manage the system using command-linetools.

You can use the screen command in Terminal or a terminal emulation applicationsuch as ZTerm running on another computer to communicate through the Xserveserial port.

To connect to the serial port:

Server MonitorYou can use Server Monitor to check the status of an Xserve and its components.

To connect from Server Monitor:Open Server Monitor (in the folder /Applications/Server/), click Add Server, and enterthe serverʼs IP address and account information.

Important: If you are connecting to an Intel-based Xserve, be sure to use the IPaddress of the serverʼs lights-out management (LOM) port when you add it in ServerMonitor.

If youʼre connecting a terminal, use a standard 9-pin serial cable.

If youʼre connecting a Macintosh, use a 9-pin serial null modem cable with aserial-to-USB adapter or a serial port concentrator.

Configure the terminal or terminal emulator to operate at 57.6 KB/s using 8 bitswith no parity.

FireWireIf the FireWire port is configured for networking, you can access the Xserve from aportable computer by connecting them with a FireWire cable.

To access an Xserve over FireWire:

Now you can use Server Monitor, Server Admin, or Terminal to manage the Xservefrom the portable.

1. If IP over FireWire isnʼt configured on both computers, open the Network pane ofSystem Preferences on each computer, enable the FireWire port, and assign each aunique, private IP address.

2. Connect the computers using a FireWire cable.
