2.7 Other useful installation information 

 

Intelligent cables

 

— The USB and Sun cables contain miniature active circuits that 

are moulded into the ends of the cable assembly. These circuits intelligently provide 

signals to your computers that make them think that a keyboard and mouse are 

continuously attached, even if the LINDY CPU Switch is not connected or powered 

on. This increases the reliability and robustness of the installation. 

 

PC boot up sequence

 - When your PCs are powered on they communicate with any 

attached keyboards and mice and setup parameters required by the particular 

operating system. It is necessary for the LINDY CPU Switch to be attached and 

powered on during this sequence so that it can give the required responses and keep 

track of all the modes and settings requested by each of the connected PCs.   

 

Mouse characteristics

 - do not unplug a PS/2 mouse connection from a PC whilst 

the PC is on. Due to the design of PS/2 mice communications the mouse function on 

the PC will be lost and you will have to re-boot the PC to regain normal operation. 

RS232 mice can usually be unplugged and plugged back in provided that a mouse 

was connected when the operating system initially booted.  

 

Keyboard and mouse mode switching

 - The LINDY CPU Switch keeps a log of the 

keyboard and mouse mode and resolution settings requested by each of the 

connected PCs. These settings are automatically restored to the shared keyboard 

and mouse when the LINDY CPU Switch channel is switched thus ensuring 

maximum software compatibility. The keyboard num, caps and scroll lock states are 

an obvious example of this process. 

 

 

2.8 Hot plugging the LINDY CPU Switch into running systems and 

re-enabling disconnected CPU PS/2 mouse connections 

 

It is advisable to switch off the systems that are going to be connected to the LINDY 

CPU Switch before installation. However if this is not possible then most systems 

can be hot plugged by using the LINDY CPU Switch’s mouse restoration functions. 

The keyboard connection will normally restore itself automatically. 

 

On many PCs, mouse movement will be lost if the PS/2 mouse is unplugged and 

plugged back in whilst the PC is running. Mouse movement can then only be 

restored by rebooting the PC. This is because the mouse drivers only setup and 

enable the mouse when the PC is initially booted.
