Power Supply Status
Using the Serial Port
You can connect a terminal or a computer running terminal emulation software to the
Xserve serial port, and then monitor the system using command-line tools.
About Terminal Emulation Software
You can use a terminal emulation application such as ZTerm running on another
computer to communicate through the Xserve serial port. You can’ t use the Terminal
application that comes with Mac OS X to communicate with the serial port.
You must configure the terminal or terminal emulation software to operate at:
 57.6 KB/s using 8 data bits with no parity
Connecting to the Serial Port
You can use a 9-pin serial null modem cable with a serial-to-USB adapter or a serial port
concentrator to connect a Macintosh computer to the serial port.
For information about the pin assignments for the serial port connector, see the
specifications appendix in the printed Xserve Setup Guide that comes with the Xserve.
