CHAPTER 1 SETUP This section describes the features and part names of the server switch unit. Also describes the installation and handling of the server switch unit. FEATURES This server switch unit allows the connection of multiple servers to a single console (monitor, keyboard and mouse). This greatly saves installation space by reducing the number of dedicated consoles required for each server. A single server switch unit enables the user to select a specific server from up to eight servers.
Hot keys can be set by selecting one of three key entries; depression of Ctrl + Alt + Shift keys or two successive depressions of Ctrl key or Scroll Lock keys. This allows the user to avoid using a specific key sequence used in another application as the hot key. Thus, the hot key can be utilized more effectively.

IMPORTANT：Connect the server switch unit with UPS having the highest boot priority within the system. If any server connected to the server switch unit starts in prior to the server switch unit, the server switch unit may fail to operate correctly.
CHAPTER 2 USING THE SERVER SWITCH UNIT This section describes the fundamental operations of the server switch unit. SWITCH OF SERVER SWITCH UNIT A specified server can be selected in two ways, the use of the server selection switch and the use of the keyboard (hot key). If the server of the port being selected is off-powered, the selection remains unchanged. The server switch unit does not automatically select another server.
SELECTION OF SERVER VIA SERVER SELECTION SWITCH (NORMAL MODE) To select a server, press the server selection switch of the desired server. When the server is selected, the server selection lamp of the designated server will light. The name of the selected server will be displayed in the upper left corner of the screen for approximately three seconds.
SELECTION OF SERVER ON KEYBOARD (HOT KEY MODE) You can select a server using a keyboard (in hot-key mode). There are two hot-key modes; OSD (On Screen Display) selection mode and direct selection mode. When the server switch unit enters the hot-key mode, the OSD screen appears on the console. The Scroll Lock LED on the keyboard blinks rapidly, and the other LEDs (Num Lock LED, Caps Lock LED) are turned off. Keyboard and mouse operation for the server are disabled during hot-key mode.
ENABLE/DISABLE HOT-KEY MODE Hot keys can be enabled or disabled by changing of DIP switch setting on the rear of the server switch unit. SW No SW1 SW2 SW3 Description Enables/disables the hot-key [Ctrl+Alt+Shift] and the Hot-Key switch. Enables/disables the hot-key [Ctrlx2]. Enables/disables the hot-key [Scroll Lockx2]. Note:See “DIP Switch”for any other setting.
WHEN ENTERED HOT-KEY MODE IN OSD SELECTION MODE: If you enter the hot-key mode in OSD selection mode, the OSD selection screen appears on the server screen.
DESCRIPTION OF SCREEN 1. The status of the master server switch unit appears at the left side of the screen with black background. 2. The status of the slave server switch unit (connected with the server switch unit in cascade) appears at the right side of the screen with blue background. 3. The purple character strings with blue background indicate port for the server you are going to select by the cursor key. Move the cursor by <↑> or <↓> key to select a server and press to determine it.
9. When you select a port which is in cascade connection on the master side screen, or select a port on slave side screen and press the key, 14 characters are displayed on master side and 5 characters on slave side. Releasing the key will return to the original display. Left: When a port in cascade connection is selected on master side Right: When a port is selected on slave side NOTE：While the Shift key is pressed, any other key entries are disabled.
SELECTING SERVER IN OSD SELECTION MODE SELECTION USING KEYBOARD 1. Select a port of the server switch unit on the master side of the OSD screen by using cursor keys (↑and ↓). 2. If the slave server switch unit is connected to the selected port in cascade, the status of the server subject to the cascade connection appears on the slave side of the screen. 3.
SELECTION WITH MOUSE IN OSD SELECTION MODE You can use the scroll-mouse to select a port. 1. On the master side of OSD screen, move the mouse cursor to the desired port. The mouse scroll corresponds to the <↑>, and to the <↓>. 2. When you move the mouse cursor to the port that is connected with the slave server switch unit in cascade, the status of the server switch unit is displayed on the right side of the OSD screen. 3.
ENTERING HOT-KEY MODE IN DIRECT SELECTION MODE When you enter the hot-key mode in direct selection mode, the OSD menu appears on upper left of the LCD screen.
OSD MENU IN DIRECT SELECTION MODE 1. The OSD menu appears on upper left of the LCD screen (the same location as for server name display, with red background) indicating the status of server switch unit. NOTE：The server name used for port selection is displayed in blue background. In the OSD menu, the background is red. 2. When the port is selected, the background color changes to blue. Selecting the server exits from hot-key mode. By the default, the server name disappears about 3 seconds later.
AUTO SCAN MODE (COMMON TO OSD SELECTION MODE/DIRECT SELECTION MODE) Keyboard and mouse operation are disabled during Auto Scan mode. 5. If you press the <0> (zero) key on OSD screen, the screen display is automatically switched in a certain period. 6. The screen display is switched in ascending order of the port number. When the screen goes to port 8, then returns to port 1. For auto scan sequence in cascade connection, the ports of slave server switch unit are included in the port of the master side.
DISPLAY/HIDE THE SERVER NAME Server name display area The server name can be continuously displayed on the upper left corner of the screen, or hidden. To display the server name, press the Scroll Lock key twice while holding down the Shift keys in normal operation of the server (except for Hot Key mode or Auto Scan mode). To hide the server name, press the Scroll Lock key twice while holding down the Shift keys while the server name is continuously displayed.
REGISTRATION OR CHANGE OF SERVER NAME 1. Enter the hot-key mode in OSD selection mode (press the Hot-Key button, press the + + keys, or press the key twice). 2. Move the cursor to the port for the server you are going to register or change the name. 3. Press the key. 4. The color of the character string is changed to yellow but only a single character has the yellow background. 5. Type the name on the keyboard and press the key.
SETTING OF CONSOLE INFORMATION The console information of factory-installed Default-Monitor is set as default in every port of the server switch unit. Setting of console information in the server switch unit is required when connecting the slave server switch units in cascade.
