SERVSWITCH™ WIZARD EXTENDER

5.5 Keyboard Control: Hotkey Commands

You can control several functions on the ServSwitch Wizard Extender—including CPU connection/disconnection, screen blanking, locking, and entering configuration mode—from the keyboard, using commands triggered with the Extender’s currently selected hotkey combination. All of the hotkey-control commands are invoked by holding down the two hotkeys and then pressing a command key. By default, the two hotkeys are [Ctrl] and [Shift], but you can change them to [Alt] and [Shift] or [Ctrl] and [Alt] by setting positions 2 and 3 of the DIP switch on the Extender’s receiver (see Section 4.2.1).

Normally, when you send a hotkey command, you have to release the hotkeys and the command key before you can send another one. The one exception to this rule is {Hotkeys} + [Tab], one of the “connect to the CPU” commands; for as long as you hold down the hotkeys, the Extender will execute the connect command each time you press [Tab]. (Originally, this command was designed to “tab through” the CPU ports on compatible switches such as the ServSwitch Duo and Quadro; repeating it doesn’t do anything useful on the Extender, but you should keep in mind that the Extender will keep absorbing the [Tab] keystroke until you release the hotkeys.)

The hotkey commands are summarized below. Note that to generate the numeric digits in the commands that contain them, you need to press the number keys on the top row of the main section of the keyboard, not the number keys on the keypad; the Extender will not recognize keypad numbers.

•Use {Hotkeys} + [1] or {Hotkeys} + [Tab] to select the attached CPU or KVM switch if it’s been deselected.

•Use {Hotkeys} + [0] to deselect the attached CPU or KVM switch and select nonexistent “CPU zero.” This causes the Extender to disable keyboard and mouse input to the attached CPU or switch (although Extender commands will still work) and shut off the video output to the attached monitor. (Be aware that this will cause some monitors to go into standby mode or shut themselves off.) You can re-enable video by reselecting the “real” CPU or switch.

•Use {Hotkeys} + [L] to lock the receiver. If no password has been set for the Extender (see Section 4.4), this command is equivalent to the {Hotkeys} + [0] command. If a password has been set, this command also causes the receiver to

(a) stop accepting keyboard and mouse input except for password attempts until someone enters the password and (b) alternately light the Num Lock/ Scroll Lock LED pair and the Caps Lock LED on the attached keyboard. Note that if anyone has tried to type something at the receiver’s keyboard while the
