SERVSWITCH™ DUO AND SERVSWITCH™ QUADRO
5.3 Logging Onto the Duo/Quadro System
If password security has been turned on the ServSwitch Duo/Quadro system (see
Section 4.3), the login window shown in Figure 5-3 will appear when the Duo/
Quadro is switched on or when no user is currently logged in. (The previous user
may have blanked the screen with the screen-saver function. If so, you may need to
press a key before the login window appears.) Type in your user name and
password to access the Duo/Quadro.

5.4 Things to Keep in Mind About the Keyboards and Mice
CPU bootup sequence: When your computer CPUs are powered on, they
communicate with any attached keyboards and mice and load the setup
parameters required by their particular operating systems. It’s necessary for the
ServSwitch Duo/Quadro to be attached and powered on during this sequence so
that it can give the CPUs the required responses and keep track of all of the modes
and settings requested by each of the connected CPUs.
Mouse characteristics: Do not unplug a PS/2 mouse connection from a computer
CPU while the CPU is on. Because of the way PS/2 mice communicate, the CPU
will lose mouse function and you will have to reboot the CPU to regain normal
operation. Unplugging a shared PS/2 mouse from the ServSwitch Duo/Quadro
will have no immediate effect, but the selected CPU will lose mouse function as
soon as you plug the mouse back in. (RS-232 mouse-port connections can usually
be freely unplugged and replugged, provided that a mouse was connected when
the operating system initially booted.) The ServSwitch Duo/Quadro has a PS/2
mouse-recovery system which allows you to disconnect and reconnect the shared
mice without powering down the system, but we recommend using this only when
absolutely necessary. See Section 5.7 for details.
Keyboard- and mouse-mode handling during channel switching: The ServSwitch
Duo/Quadro keeps a log of the keyboard and mouse modes and resolution
settings requested by each of the connected computer CPUs, including the
keyboard Num Lock, Caps Lock, and Scroll Lock states. These settings are
automatically restored to the user-station keyboards and mice when channels are
switched, ensuring maximum software compatibility.
