13 CHAPTER 2: Introduction 2. Introduction Thank you for choosing a Matrix ServSwitch™. Designed with your needs in mind, your new Switch will simplify your job by helping you organize your multiple- computer application. With your Switch you can use two keyboards, monitors, and mice to access a number of IBM ® PC compatible computers, so you ca[...]

14 MA TRIX SERVSWITCH™ 2.2 Features With the Matrix ServSwitch, you have easy, virtually trouble-free, secure, and complete access to up to 1000 computers from as many as four keyboard/video/ mouse stations. Here are some of the major features of the Switch: Upgradability: • The plug-in Expansion Module gives your Matrix ServSwitch system room [...]

15 CHAPTER 2: Introduction Flexibility: • Full-featured command set includes a scan command to automatically switch through a subset of computers over the course of an adjustable time interval. • You can use keyboard commands, on-screen menus, or RS-232 devices to switch computers to your keyboard/video/mouse station. • Integrated autoswitchi[...]

16 MA TRIX SERVSWITCH™ 2.3 The Front Panel The Switch’s front panel features two pushbutton switches and several LED indicators. To familiarize yourself with these controls and indicators, refer to Figure 2-1 and the descriptions that follow on the next page. Figure 2-1.

The extra slots in the chassis of the 2 x 4 model are left blank, but are protected by material mounted inside the chassis. Connect the Matrix ServSwitch’s power-supply cord here. The [...]

20 MA TRIX SERVSWITCH™ 2.5 Cable Requirements Many switches of this type have what seems like ten million connectors on their rear panels: one for each CPU’s video cable, one for each keyboard cable, and a third for each mouse cable. The potential for tangling or mismatching cables is high. By contrast, you can connect the Matrix ServSwitch to [...]

21 CHAPTER 3: Installation and Preconfiguration 3. Installation and Preconfiguration 3.1 Quick Setup Guide Figure 3-1 shows a basic example of taking a Matrix ServSwitch and connecting it to a CPU, a user station (monitor, keyboard, and mouse), another Switch, and AC power. IBM PC equipment is shown, but the principles will be similar for all equip[...]

22 MA TRIX SERVSWITCH™ 3.2 Guidelines for Using the Matrix ServSwitch with Y our Equipment 3.2.1 CPU S If you will be attaching IBM PC type computers, use only IBM PC/AT, PS/2, RS/6000 ® , or 100% compatible machines, or recent SGI ® machines. The Matrix ServSwitch does not support IBM PC/XT™ or compatible machines. It also does not support m[...]

23 CHAPTER 3: Installation and Preconfiguration particular, use Windows keyboards if any of your applications require the Windows keys, and use three-button mice if any of your applications require the center mouse button. Other concerns: • The Matrix ServSwitch emulates several types of mice for the attached computers, but the actual mice used a[...]

24 MA TRIX SERVSWITCH™ • The Matrix ServSwitch is designed to support IBM PC compatible 101-, 102-, 104-, or 105-key keyboards and IBM PC keyboard-scan modes 1, 2, and 3; it’s also designed to work with PC-type CPUs/keyboards that use 5-pin DIN or 6-pin mini-DIN keyboard connectors. The Matrix ServSwitch will try to pass through keyboard code[...]

25 CHAPTER 3: Installation and Preconfiguration T able 3-1. Keyboard mapping by the Matrix Ser vSwitch. Generally, the Matrix ServSwitch interprets keys by their positions on the keyboard, so any keys that occupy more or less the same positions and perform more or less the same functions across platforms will map one-to-one. However, certain keys a[...]

26 MA TRIX SERVSWITCH™ 3.2.3 M ONITOR If all of your CPUs are of the same type, we recommend that you use the corresponding type of monitor. If your CPUs are of different types, the monitor must be a multisync model, able to sync to every CPU’s video-output frequencies, and compatible with all of the CPUs’ video cards. While PC-type CPUs and [...]

27 CHAPTER 3: Installation and Preconfiguration The Matrix ServSwitch will support SVGA (Super VGA) video, but with original Serv cables the video quality can decrease at higher resolutions and distances. Table 3-2 illustrates this. The distances in the table are total lengths of CPU Cable and User Cable (but not Expansion Cable) measured from the [...]

28 MA TRIX SERVSWITCH™ By contrast, coaxial cables (standard for Sun applications, required for XGA applications, and recommended for most other applications) do much better at maintaining video quality, as shown in Table 3-3. (For the meaning of quality numbers 3 , 2 , and 1 , see the bottom of the previous page.) As before, the distances in the[...]

29 CHAPTER 3: Installation and Preconfiguration 3.3 Installation Procedure This section provides complete instructions for the hardware setup of a single Matrix ServSwitch. (For detailed instructions on installing a daisychained Matrix ServSwitch system, see Sections 3.3.6 and 3.4 .) For an illustrated example of the elements of a basic setup, see [...]

30 MA TRIX SERVSWITCH™ 3.3.3 R ACKMOUNTING (O PTIONAL ) If you want to mount the Matrix ServSwitch in a rack, you will need a ServSwitch Rackmounting Kit. Our product code for a 19", 23", or 24" Kit that fits the 2 x 4 and 2 x 8 Matrix ServSwitches is RMK19B, RMK23B, or RMK24B respectively. Our product code for a 19", 23"[...]

31 CHAPTER 3: Installation and Preconfiguration 3.3.5 C ONNECTING CPU S CPU Cables run from the Matrix ServSwitch to the keyboard port, mouse port (if this is separate), and video-output port of each CPU you want to directly attach to it. Different types of this cable fit the connectors on different computers (see Appendix B ). This cable also come[...]

32 MA TRIX SERVSWITCH™ 6. Plug each (remaining) CPU Cable’s video-, keyboard-, and (on IBM type cables) mouse-port connectors into the corresponding ports on each CPU (or into the Video Adapter on a non-VGA Mac). For various reasons, the CPU should be OFF when you do this. (The Switch also needs to be configured before you turn ON the CPUs; see[...]

33 CHAPTER 3: Installation and Preconfiguration 3.3.7 P OWERING U P THE S WITCHES 1. Making sure that the connected CPUs are OFF (powered down)—except for at least one CPU in an all Sun installation where the monitor doesn’t support 640 x 480 (see step 5 in Section 3.3.5 )—take the power cord of a Matrix ServSwitch in your system and plug the[...]

To take full advantage of the Switch’s keyboard-command features, refer to Chapter 6 , which gives detailed informat[...]

35 CHAPTER 3: Installation and Preconfiguration 3.4 Daisychaining Matrix ServSwitches Chaining multiple Matrix ServSwitches together adds capacity for more computers and, optionally, more user stations. When you plan a daisychained system, keep in mind that Switches attach to each other: • From output to input. • In a bus or ring topology. • [...]

36 MA TRIX SERVSWITCH™ 3.4.2 T OPOLOGIES IMPOR T ANT NOTE A standard Matrix ServSwitch system can support two independent users, but each of the user stations has to be attached to a different- numbered KVM port (one to KVM 1, the other to KVM 2), even if the stations are attached to different Switches. If you have users on stations attached to s[...]

37 CHAPTER 3: Installation and Preconfiguration Figure 3-4. The ring topology . Use a ring arrangement if you have user stations attached to two different Matrix ServSwitches and you want both of the users to have access (or at least potential access) to all CPUs. Run Expansion Cables from the OUT ports of each Switch to the IN ports of the previou[...]

38 MA TRIX SERVSWITCH™ 3.5 The Power-Up Procedure About three seconds after you plug in and turn on a Matrix ServSwitch as described in Section 3.3.7 , a diagnostics screen running a self-test will appear on user-station monitors and serial devices attached to the Switch. (In an all Sun installation with a monitor that doesn’t support 640 x 480[...]
