CHAPTER 4: Operation: Hardware and Keyboard Commands

4.2 Keyboard-Command Summary

Table 4-4 below and on the next page summarizes the commands that can be sent to the ServSwitch. To enter any command at the shared keyboard, first press and release the left Control key, represented by “[Ctrl].” (This cues the Switch to look for commands from that keyboard.) Then enter the command followed by any arguments you wish to specify (the port number, for example).

Letter commands are not case-sensitive; they are all shown in uppercase for clarity only.

When you enter numeric commands or arguments, use only the numbered keys at the top of your alphanumeric keyboard. Numbers entered from the numeric keypad to the right will not be recognized as valid commands.

All of these commands have a two-second timeout between characters. This means that if you begin entering a command, but you stop for more than two seconds at any time before you type the final character, the command is aborted and the ServSwitch returns to normal operation. This keeps the Switch from getting stuck waiting for you to finish the command.

The [Ctrl] character is always passed through to the CPU. The command characters and operands, however, are absorbed by the ServSwitch and are not sent to the CPU.

Many of these commands have factory-default values (see Appendix A) that can be reloaded if your Switch becomes badly misconfigured; see Section 6.1.
