To take full advantage of the Switch’s features, refer to Chapter 4, which gives detailed information about each of the ServSwitch commands, describing each command’s function and keystroke sequence. For your convenience, this info is summarized in Section 4.2.
  • Page 49 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 52 • 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’ CPU ports. To illustrate this restriction, let’s say you’ve installed a four-port submaster on a four-port ServSwitch master and you have a four-port submaster yet to install.
  • Page 53 ServSwitch, and then set Width to 8 (and Units to 2 and Max Ports to 20—see Sections 5.2.3 and 5.2.4), you will be unable to scan or switch to the upper 4 ports on the 12-port submaster—the Switch has no way of knowing they are even there.

    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.
  • Page 56 DOS commands, that change the settings of the mouse port after the driver has been loaded. • When you first switch between CPUs, you might notice wide variations in mouse sensitivity (how far or fast the mouse moves) from CPU to CPU. This is normal.
  • Page 57 SERVSWITCH™ 4.1.3 M ONITOR At resolutions up to 800 x 600, the video quality for most ServSwitch applications will be excellent. At higher resolutions, however, you might see a little fuzziness on your monitor no matter how close to ideal your ServSwitch system is.
  • Page 58 CHAPTER 4: Operation: Hardware and Keyboard Commands 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.
  • Page 59 CPUs before installing this cable in lengths greater than 20 ft. (6.1 m). For CPU-to-monitor distances over 200 feet (61 m), Station Extenders or CAT5 KVM Extenders might be required. Call Black Box for technical support to discuss this option.

If you press the key of only one digit, and do not follow it with [Enter], the Switch will wait two seconds for you to press [Enter] or another numeral key; then, if no key is pressed, it will switch immediately to the single-digit port.
  • Page 63 SERVSWITCH™ 4.3.3 S To start scanning (switching from CPU to CPU in a continuous rotation) from the keyboard, press and release the left Control key ([Ctrl]), then press [S]. The ServSwitch will begin scanning sequentially from its currently selected port through the higher-numbered ports, then begin again at CPU Port 1.

  • Page 69: Upgrading The Firmware (Flash Memory)

    ServSwitch will not let you load firmware intended for other Serv models (UxxP.HEX, UxxS.HEX, etc.). There are two ways to load the firmware into the Switch, as described in the following two subsections.
  • Page 70 5, but the firmware will remain unchanged. If the trouble recurs and you can’t pinpoint it, call Black Box for technical support. 5. If the file transfer is successful, press the space bar on the PC’s keyboard.

  • Page 71: B Upgrading The Firmware With The Dos Copy Command

    It should then send the message: Hit enter to continue (If you get an error message at any time during this phase, call Black Box for technical support.) 7. Press the Enter (or Return) key again. The Switch should return to normal operation with port 1 selected (LED 1 lit).
  • Page 72 Once this phase is successfully completed, LED 3 will light. If, however, an error occurs, LED 3 will remain dark, and you’ll have to go back to step 3. If the second attempt doesn’t work, call Black Box for technical support.

    1. Configure the ServSwitch through a series of configuration menus (triggered with the [Ctrl] [F12] command, where [Ctrl] is the left Control key). 2. Switch to different computers from a window which shows a list of computer names (triggered with the [Ctrl] [ESC] command, where [Ctrl] is the left Control key).

    You can choose between either “PC 101/102” (regular IBM PC compatible) or “PC 104/105” (IBM PC Windows compatible) keyboard. (If you power up a Switch when no shared keyboard is attached to it, this setting will default to “PC 104/105.”)

    Actually, the Switch will usually autodetect this value, but if for whatever reason you have no CPUs attached the first time you boot the Switch, it will use its factory- default values instead (“4” for 2-port units, the number of CPU ports on the box for other units).
