C	MONITOR UTILITY

This appendix describes how to access and use the monitor utility, which consists of commands and parameters that reside in the motherboard’s firmware. Monitor mode suspends normal operation and allows interaction only with the monitor command interface. Using this utility, you can perform the following tasks:

■Boot or reset the server.

■Copy and format diskettes.

■List and delete files on a diskette.

■Dump the contents of the server’s memory to diskettes or the network.

■Display current settings of firmware parameters.

■Modify firmware parameters to customize the operation of your server.

After using the monitor, you must reboot the communications server to resume normal operation.

Procedures for displaying and modifying firmware parameters appear in greater detail in Chapter 4, “Configuration.”

Entering the Monitor To access the monitor utility, you must attach a terminal to the console port, located on the CS/2500 series server’s back panel. Configure the terminal to 9600 bps, 8 data bits, 1 stop bit, and no parity.

These instructions assume the default firmware configuration. If you have used firmware configuration commands to change the baud rate or to select a different console port, modify the instructions accordingly.

You can access the monitor in either of the following ways:
