SERVSWITCH™ JR. MP

4. Operation

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

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

NOTES

To start any ServSwitch Jr. MP 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 Switch 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 Jr. MP with Your Equipment

4.1.1 CPUS

Use only IBM PC/AT or PS/2 or 100% compatible machines on the PC side. The ServSwitch Jr. MP does not support IBM PC/XT™ or compatible machines. It also does not support machines that output CGA or EGA video.

4.1.2MOUSE AND KEYBOARD

When you power up your ServSwitch Jr. MP system, make sure that your CPUs, mice, and keyboards are properly cabled to the ServSwitch Jr. MP. When you boot up the CPUs, the ServSwitch Jr. MP should start operating automatically. (You should be able to freely disconnect and reconnect a mouse or keyboard from a ServSwitch Jr. MP while the Switch is ON, but if you experience problems when you do this, issue the Reset command [CTRL] R—see Section 4.3.4.)

The mouse must be a 2-button PS/2 type mouse by Microsoft or Logitech™, or a 3-button or “wheel” PS/2 mouse such as the Microsoft IntelliMouse.

The ServSwitch Jr. MP is designed to support IBM PS/2 compatible 101- through 105-key keyboards and IBM keyboard-scan modes 1, 2, and 3, and it’s designed to work with keyboards that use 6-pin mini-DIN keyboard connectors. The Switch
