1.0 USB ServerSwitch - Introduction
The USB ServerSw itch is an intelligent KVM switch for keyboard, high-resolution video and mouse for a 2-User by 8-server configuration. The USB ServerSwitch (for simplicity, it may be referred to as the “USBSS”) supports individual USB keyboards and mice. The USB ServerSwitch has full-time keyboard and mouse emulation to each PC or server. This assures th at there will be no interruptions or interference to boot processes or other CPU activity. The video switching circuitry is designed with state of the art video multiplexers that support high-resolution graphics adapters with video resolutions of 1600 x 1200 pixels.
Figure 1: USB ServerSwitch - Front Panel
The USB Se rverSwitch front panel has a built-in 24 character, 2 line backlit LCD display. The top line displays Port data f or the currently-selected server port, and the bottom line is dedicated to real-time status monitoring. The USB ServerSwitch can be controlled either through on-screen menus (see section 3.0) or directly using the Up and Down buttons on the USBSS (see Section 3.3).
The USB ServerSwitch’s rear panel provides USB connections for Keyboard and Mouse and HD15 Video for 8 Servers (Inputs), 2 USER/OUTPUT console positions, and CONTROL and Video Cascade ports for expanded configurations (see Section 6.0) that supports up to 64 connected servers. Also found on the back panel is the AC power input, fuse, and Power Switch for the unit.
Figure 2: USB ServerSwitch - Rear Panel
The USB ServerSwitch is designed for rack mounting in a conventional 19-inch equipment rack, requiring 1RU (1.75 inches) of rack height. The unit may also be placed on a shelf; and the included rack mounting flanges are removable. The unit is convection cooled and does not require a fan or air conditioning.

2.0 USB ServerSwitch - System Information
2.1 Video
The USB ServerSwitch incorporates an active, high-bandwidth switch for graphics adapter cards supporting resolutions up to 1600 x 1200 pixels. The system supports DDC2B video records, and maintains a local copy of the video record for each attached server (after a proper power-up sequence). A constant impedance of 75 ohms is maintained on all video lines in the USBSS, so that the video signal is not compromised by mismatched impedance. Monitor sense lines are also transported by the USB ServerSwitch. The ID lines are buffered and passed f rom the monitor to the attached graphics adapters in the servers.
Note: The USB ServerSwitch's USB interface is for discrete USB mice and keyboards only, and will not support Monitors with USB-provided video controls.
DDC2B Support
The DDC2B video record is generated during the power-up of the system, and is generated by each server that supports or requires the video record, or else defaults to a generic VGA mode. The USBSS stores a copy of the DDC2B record at each Server port, and when that server is switched to the User, that video record information will be sent to the monitor for a proper video signal.
The video record is determined upon power-up of the system by checking the video signal with the monitor connected to the User A port, and then the User B port. If monitors are changed at a later date, it may be necessary to shut down the USB ServerSwitch and/or the servers to regene rate the proper DDC2B record.
If using DDC2B, it is recommended that both User A and User B have similar video monitors at their stations, since the DDC2B only supports one video record per server.
2.2 Keyboard / Mouse
The USB ServerSwitch is an intelligent USB switch for the keyboard and mouse. Each port emulates the keyboard and mouse fully, allowing an attached server or PC to boot without having been previously selected. Power for each connected device is monitored from the USB port.
Note: The USB ServerSwitch's keyboard and mouse interface is for discrete USB mice and keyboards. It does not support graphics tablets, scanners, modems, drives, hubs or other composite USB devices. Each USB-A receptacle on the USBSS will support one USB mouse or USB keyboard.
If there is no connection on a USB server port, a status message "Inactive port" will be displayed on the front panel display. The other attached servers are not affected because of the keyboard and mous e emulation.
Each port maintains a local copy of the keyboard and mouse configuration. USB Port numeration is maintained even when the user has de-selected a port. When
Lightwave Communications USB SERVERSWITCH
the user switches from one port to another, the keyboard is set up just as it was prior to switching to another port. The mouse behaves in a similar manner.
2.3 System Control
The USB ServerSwitch is controlled either by using the UP and DOWN arrows on the front panel of the unit or via On-Screen Menus from their Console (Keyboard, Monitor and Mouse).
The USBSS is a transparent device to the User. The User (of which there may be one or two) can select which server they wish to access from their Console, from up to 8 connected Servers. In cases where two or more USBSS units have been cascaded, additional Servers can be accessed by the two Users, up to a maximum of 64 Servers (8 units cascaded in all).
To access the USBSS’s switching capability, the User must “wake up” the on­screen display to control the system by pressing both ‘Cntl’ keys simultaneously (referred to as ‘Cntl-Cntl’), or press the Scroll Lock key twice (within one second) on their keyboard.
If the system administrator is near the USBSS (for example, in a backroom location), the sysadmin may instead select a server by using the Up and Down buttons on the front of the unit. The display will scan through which Servers are available, if auto-scan is active. Server selection can also be accomplished manually by pressing the Up arrow or Down arrow buttons. To select between User A and User B, press both Up and Down buttons on the front panel of the USBSS at the same time to shift between the two users.

3.0 On-Screen Menus
On-screen Menus are used for two purposes:
• Server Port selection for a Console
• System setup programming for the USB ServerSwitch
On-Screen Menus are displayed on the User's monitor. Either Console may administer the system, but only one user may edit the setup at a time.
NOTE: While in the on-screen menu mode, the "Caps Lock", "Num Lock", and
"Scroll Lock" LEDs will flash on the User Console’s keyboard.
Navigating the on-screen menus
• Press both Control keys (Cntl-Cntl) to access the on-screen menus, or press the Scroll Lock key twice (within one second)
• Up Arrow/Down Arrow
• + and - keys on number pad
• Enter (select or scroll through options)
• Esc to exit, or to back up one level
• Most options have a single-character hot-select key, highlighted and
capitalized on the screen. Press that letter to select that option.
3.1 Main Menu
Pressing and releasing both CONTROL buttons (Ctrl-Ctrl) on either Console's keyboard will bring up the main menu of the USB ServerSwitch.
