Compaq Server Console Switch User Guide xiii 1 Introduction Product Overview The Compaq Server Console Switch enables the user to control large computer networks using a single keyboard, video, and mouse (KVM). With a single video screen, the user can select as many as 64 computers running different operating systems. The 4-Port and 8-Port console switches use an On-Screen Display (OSD) interface, which has menus for accessing each attached computer. Computers can be identified by name or number, enabling the user to view and select server names. NOTE: The 2-Port console switch uses a simplified OSD. A typical Compaq Server Console Switch, also known as a KVM configuration, consists of the console, the switch unit, and the attached computers. The user can choose from a single-user system, multiple user system, or a tiered system. Tiering increases computer access from 4 to 8 computers to as many as 64 by adding additional Server Console Switches to the primary console switch, allowing the user to modify the system, as network system needs change. Two 8-Port console switch units offer dual console capabilities, allowing console switch configurations to be controlled from more than one location or by more than one user. Compaq Server Console Switch User Guide 1-1 Introduction To switch between computers, simply enter a command at the keyboard. The selected computer receives characters entered at the keyboard and displays its video output on the monitor. The user can also use the mouse to interact with the graphic interface of the selected computer. The Compaq Server Console Switch family of products is available in 2-, 4-, and 8-Port versions and can be used in various configurations to accommodate large or small systems. All versions are packaged in space-efficient 1U height (1.71-inch) cases. This chapter provides an overview of the Server Console Switch features, functionality, and sample configurations.

During startup, the console switch does the following: · · Identifies the mouse and keyboard and puts them into default states. Switches to port 1 by default, and displays the number "1" in the status flag displayed on the monitor. If the status flag default setting has been changed to Names mode, the status flag displays the port name instead of the port number. If a status flag is not shown on the monitor, make sure the computer is connected and powered up. 3-8 Compaq Server Console Switch User Guide Cabling Power up the system as follows: 1. Press the power switch located on the rear panel of the console switch to the on position. 2. Power on the computers. Computer Startup Behavior During startup, the computers send device settings to the console switch. The unit then generates standard responses to these commands and allows the computers to boot successfully without being physically connected to the keyboard, monitor, or mouse. After the console switch is installed, the user can save these settings to nonvolatile RAM (NVRAM). Refer to Chapter 4 for additional information. Configuring the Console Switch When the user first turns on the switch box, no configuration is needed for basic switching operation. To configure the unit to meet specific needs, such as assigning unique names for the computers or displaying the computers by their assigned names or port numbers, refer to Chapter 4. Unattended Reboot After a power outage, each server connected to the console switch reboots (if configured to do so) without operator intervention, when power returns. The console switch generates responses to ensure that the reboot is successful and that it is ready to switch between computers. Resetting the Unit If the keyboard or mouse locks up, press the Reset button on the back panel to reset the console switch. Pressing the Reset button allows the user to recover the device settings without power cycling the computers. Compaq Server Console Switch User Guide 3-9 Cabling Making Connections Under Power The user can connect additional computers to the console switch while it is powered up. When powering the newly connected computers, the console switch recognizes them, and the user can switch to the new computers without taking any additional steps. The user can also connect the mouse and/or keyboard to the console switch while the system is powered up. When connecting a new device, the console switch recognizes it and configures it to the settings of the currently selected computer. This technique allows failed devices to be replaced without having to restart the system. NOTE: When new computers are added to the console switch, or when existing connections are changed, the new configurations should be saved in NVRAM by using the Snapshot option from the OSD. Alternate Configurations There are other ways to configure the system, including tiered console switch configurations and dual console configurations. 3-10 Compaq Server Console Switch User Guide Cabling Tiered Switch Configurations In tiered systems, the user can connect additional console switches to ports on a primary unit. That is, console switches can be tiered in primary/secondary configurations to allow one primary console switch to switch between computers or other console switch units. Tiering involves linking the physical keyboard, mouse, and monitor of the secondary units to computer ports on the primary unit. For example, one 8-Port primary unit can accommodate eight secondary console switch units. A system with eight servers connected to each of the eight secondary console switches would provide a 1x64 concentration. Figure 3-9: Tiered configuration When connecting a secondary unit to one of the ports of the master unit, the user must indicate this connection to the primary unit by performing the "Assigning Specific Device Types" procedure described in Chapter 5. This involves entering a secondary unit designation for the associated port number instead of a monitor type. Use the designation 4-Port for a 4-port secondary and 8-Port for an 8-port secondary. The OSD allows secondary ports to be treated much like ports on the primary console switch. It may be helpful to name each secondary unit as described in "Assigning Unique Names to Computers" in Chapter 5. Compaq Server Console Switch User Guide 3-11 Cabling Connecting Tiers while the System is Powered Up If necessary, you can connect a primary unit to a secondary unit while the system is powered up. This technique can be used to isolate any problems with minimum disruption to the system. When plugging a primary console switch into a secondary unit, first connect the mouse and video cables, and then connect the keyboard cable. This is important because the primary unit interprets the keyboard connection as the secondary unit's power up. At this point, the primary unit sends initialization codes to the secondary unit, triggering device configuration. Refer to Chapter 4 for information on switching tiered systems. 3-12 Compaq Server Console Switch User Guide Cabling Dual Console Configuration The dual console configuration is available using either of the Dual Console 8-Port console switches. Use the same methods described previously to connect the cables to the unit. Then use the ports on the front of the console switch to connect an additional KVM. Refer to "Menu Screen" in Chapter 4 for information on switching connection modes. Keyboard, Mouse, and Video Cables Figure 3-10: 8-Port dual console configuration Compaq Server Console Switch User Guide 3-13 4 Using the OSD On-Screen Display The On-Screen Display (OSD) is used with the 4-Port, 8-Port, and Dual Console 8-Port units. If a 2-Port console switch is being used, refer to Chapter 5, "Using the Simplified OSD." Alternate Languages The Compaq Server Console Switch Software Utility CD contains an update to the OSD for languages other than English. Refer to the CD for information on using this utility. NOTE: Language selection is not available on the 2-Port console switch. Functions Use the OSD to perform the following basic functions: · · · Assign device types if secondary console switches are attached to a primary console switch (tiering) Assign unique names to computers Choose switch connection mode if using the Dual Console 8-Port console switch Compaq Server Console Switch User Guide 4-1 Using the OSD · · Save the hardware settings View information about the console switch system Additional functionality is described in this chapter under each of the screen headings. NOTE: The OSD operates independently of the computer operating system. Navigation The user can navigate the OSD menus and enter commands using the mouse and keyboard; however, because the console switch operates independently of the computer operating systems, OSD keyboard and mouse conventions may differ from those used when controlling the selected computer. Table 4-1 lists the special conventions used while navigating the OSD.
