Page 27: Cascading In Servswitch Systems
SERVSWITCH™ 3.3 Cascading in ServSwitch Systems In a normal cascaded ServSwitch system, the shared monitor(s), keyboard(s), and mouse (mice) are directly attached to one or more “master” Serv-Switches, while all the CPUs are indirectly attached through “submasters” (subsidiary ServSwitches, ServSwitch Ultras, ServManagers, etc.) that provide port expansion but may or may not perform any control functions of their own. -
Page 28: Cable Requirements For Expansion
Chapter 3: Installation say that CPUs 1 through 8 are “shared,” we mean that they can be accessed by either master at different times, not by both masters simultaneously.) Adding a third 4-port submaster unit would give you a total of 17 ports, and so on. (To reach all of the CPUs in cascaded systems like this, you must set Maximum computers, Width, and Units properly on the master unit;... - Page 29 SERVSWITCH™ Figure 3-2. Basic ServSwitch cascading.
- Page 30 Chapter 3: Installation • You must not cascade submasters to more than one “layer.” That is, you may connect submasters to the CPU ports of one or (with Matrix ServSwitch submasters) two master ServSwitches, but do not connect any submasters to submasters’...
- Page 31 SERVSWITCH™ • If you are attaching more than one submaster to a slimline or full-size master ServSwitch, we strongly recommend that all of the submasters have the same number of ports. This is because the Switch’s “Expansion width” command/ parameter—the value it uses to calculate how many ports each attached submaster has (see Section 5.2.5)—is global rather than submaster-specific.
- Page 32 Chapter 3: Installation If you see this, you will need to download correct firmware to the affected unit as described in Section 4.4.3, starting at the point at which the unit is ready to receive the file at 9600 baud (9600 bps). (In this case, you must download the file at 9600 bps.) 6.Turn ON the computer identified as CPU 1.

Page 34: Mouse And Keyboard
Chapter 3: Installation 4.1.2 Mouse 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. -
Page 35: Monitor
SERVSWITCH™ However, we cannot guarantee that the ServSwitch will be able to fully support—or even work at all with—any keyboard that uses nonstandard keys, connectors, or keyboard-scan modes. 4.1.3 Monitor NOTE At resolutions up to 800 x 600, the video quality for most ServSwitch applications will be excellent. - Page 36 Chapter 3: Installation Coaxial cables (required for XGA applications and recommended for most other applications) do much better at maintaining video quality, as shown in Table 4-3 below. (For the meaning of quality numbers 3, 2, and 1, see the bottom of the previous page.) As before, the distances in the table are total cable lengths measured from the CPU to the monitor.
- Page 37 SERVSWITCH™ The ServSwitches will support SVGA (Super VGA) video, but with original Serv cables the video quality will decrease markedly at higher resolutions and distances. Table 4-2, below, illustrates this. The distances in the table are total cable lengths measured from the CPU to the monitor. The table assumes that one ServSwitch is between the CPU and monitor;...
