SERVSWITCH™

4.Operation: Hardware and Keyboard Commands

The first part of this chapter, Section 4.1, gives you some guidelines that you should follow to make sure your ServSwitch works properly with your equipment.

Section 4.2 summarizes the ServSwitch’s keyboard commands, and Section 4.3 describes these commands in detail.

Section 4.4 outlines how you can select ports or upgrade firmware from an optional computer or terminal connected to the ServSwitch’s RS-232 port.

IMPORTANT NOTES

If, as you prepare to operate the ServSwitch, you see a prompt on your screen asking you to “Enter password,” you must type in the unit’s access password before the ServSwitch will allow you to enter commands. See Section 5.5.2.

To start any ServSwitch keyboard command, you must press and release the left Control Key ([Ctrl]). Pressing and releasing [Ctrl] cues the Switch to expect command characters from the keyboard. You then have two seconds in which to start entering a valid command. If no command is begun within two seconds or if an invalid command is entered, the ServSwitch aborts the command.

When entering commands that contain numbers or math symbols, use only the numeral keys located at the top of your alphanumeric keyboard. Numbers and symbols entered from the numeric keypad to the right will not be recognized as valid.

4.1 Guidelines for Using the ServSwitch with Your Equipment

4.1.1 CPUS

Use only IBM PC/AT or PS/2 or 100% compatible machines. The ServSwitch does not support IBM PC/XT™ or compatible machines. It does not support machines that output CGA or EGA video. SGI machines must output the current type of SGI video on 13W3 connectors or standard VGA video on HD15 connectors.

4.1.2MOUSE AND KEYBOARD

When you power up your ServSwitch system, make sure that your CPUs, mouse (mice), and keyboard(s) are properly cabled to the Switch (or to the appropriate master or submaster unit). When you boot up your CPUs, the master(s) and/or submasters to which they are connected should already be ON. Unless it’s absolutely necessary, don’t disconnect and reconnect a mouse or keyboard from a ServSwitch while the Switch is ON; if you have to do this, issue the Reset command ([Ctrl] R—see Section 4.3.6) after you reconnect the mouse or keyboard.
