Page 17: Cable Requirements
ServSwitch Jr. NOTE To share an IBM 9515, 9517, or 9518 monitor, you will need special cabling. Call Black Box for technical support; we can give you a quote on these types of cable. 2.6 Equipment Requirements If the CPUs you will be controlling through your ServSwitch Jr. are not all of the same type, you will have to be careful to choose a common monitor, keyboard, and mouse that adequately support all of the CPUs. -
Page 18: Installation
CHAPTER 3: Installation 3. Installation 3.1 Rackmounting (Optional) If you want to mount the ServSwitch Jr. in a 19", 23", or 24" rack, you will need a ServSwitch Rackmounting Kit. The Switch is pre-drilled to accept the Kit’s rackmounting screws. See Appendix C for more information. 3.2 Connecting the Monitor, Keyboard, and Mouse CAUTION! Make sure that the monitor, keyboard, and mouse you plan to use can... -

To go even farther, you might want to use Station Extenders or CAT5 KVM Extenders (see Appendix B), but please call Black Box Tech Support to discuss your application. 1.

Page 20: Powering Up The System
CHAPTER 3: Installation 3.4 Powering Up the System Power up the connected CPUs one by one, giving each one time to boot completely before turning ON the next one. (After you turn ON the first CPU, the ServSwitch Jr. itself will begin operating; it gets its power from the CPUs and has no ON/OFF switch.) The Switch emulates all keyboard and mouse functions for automatic boot-up, although you might have to issue the Mode command Mn (see Section 4.3.11) to get proper keyboard communication. -
Page 21: Operation
SERVSWITCH™ JR. 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. works properly with your equipment. Section 4.2 summarizes the ServSwitch Jr.’s keyboard commands, and Section 4.3 describes these commands in detail. - Page 22 CHAPTER 4: Operation Because the ServSwitch Jr. currently only supports “stream mode” (continuous) mouse data but the IBM ThinkPad has to handle mouse data in “prompt mode” (burst-on-request), don’t try to attach any ThinkPad computers to the Switch, either directly or through docking stations. Use only the generic Microsoft mouse driver MOUSE.COM, version 4.0 at least and preferably version 9.01 or higher.

Page 23: Monitor
SERVSWITCH™ JR. 4.1.3 M ONITOR The ServSwitch Jr. is designed to support standard VGA video, including VGA monochrome (“page white”). It does not support PCs that use CGA, EGA, or proprietary versions of VGA that depart from the original specifications. Consult your PC’s manual, and if that doesn’t tell you whether or not the PC uses standard VGA, consult with the PC’s or the video card’s manufacturer. - Page 24 For CPU-to-monitor distances over 55 feet (16.8 m), you might require different cabling or an Extender system such as our Station Extender or CAT5 KVM Extender (see Appendix B). Please call Black Box Technical Support to discuss your application. One last note of caution about video: The IBM 9515, 9517, and 9518 monitors that come with some PS/2 systems are not normal VGA monitors and require special cabling in order for video to be correctly sized and synchronized.

Page 25: Keyboard-Command Summary
SERVSWITCH™ JR. 4.2 Keyboard-Command Summary Table 4-3 on this page and the next page summarizes the commands that can be sent to the ServSwitch Jr. 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 the keyboard.) Then enter the command followed by any arguments you wish to specify (the port number, for example). - Page 26 CHAPTER 4: Operation Command Keystroke Sequence Description Stop Scanning [Ctrl] X Turns Scan mode OFF (the port being scanned at the time the command is entered is given access to the shared monitor, keyboard, and mouse). Note: Scan can also be stopped by entering a Select Port command.

Page 34: Troubleshooting
POWER LED should flash three times, and the unit should be restored to the factory-default settings listed in Appendix A. Now reconfigure the Switch to your desired settings. If you’re still having difficulty, refer to Section 5.2. If it doesn’t help you to solve your problem, call Black Box for technical support. -
Page 35: Common Problems
G. If swapping ports doesn’t solve the problem, try plugging a known-good keyboard and mouse directly into the CPU that’s having the problem. If the CPU boots, the Switch might be defective; call Black Box. H. If the CPU still doesn’t boot, the CPU’s keyboard or mouse port (or other components) might be defective. -
