Hot plugging and mouse restoration
It is strongly recommended that you switch off a server before attempting to 
connect it to the ServSwitch CX. However, if this is not possible then you need 
to ‘hot plug’ the server while it is still running. There is not normally a danger of 
damage to the server, however, when mouse communications are interrupted, 
often they fail to re-initialise when reconnected. The ServSwitch CX provides 
a feature to reinstate mouse communications once the necessary connections 
have been made.
There are two main types of data formats used by current PC mice, these are 
the older ‘PS/2’ or ‘standard mouse’ format and the more recent ‘IntelliMouse
®
’ 
format introduced by Microsoft. These use slightly different data arrangements 
and it is important to know which type was being used before you hot-plugged 
the server to the ServSwitch CX. The previous setting depends both on the 
type of mouse and the type of driver, as various combinations of PS/2 and 
IntelliMouse are possible. Using the incorrect restore function may produce 
unpredictable results and require the server to be re-booted.
Which restore setting do I use?
The general rule is that unless both the mouse and the driver are both 
IntelliMouse compatible then you need to restore the mouse as ‘PS/2’. An 
IntelliMouse can operate in either mode, whereas a PS/2 mouse cannot.
Recognising an IntelliMouse-style mouse
The IntelliMouse format was introduced to support, among other features, the 
scroll wheel function. If the mouse has a scroll wheel, then it is likely to support 
the IntelliMouse format. If it is a Microsoft-branded mouse, then it will usually 
state that it is an IntelliMouse on its underside label. 
Recognising an IntelliMouse driver
Before hot plugging to the ServSwitch CX (or afterwards using only keyboard 
control), access the Windows Control Panel of the server and select either 
the Mouse option (on Windows NT, 2000 and XP) or the System option (on 
Windows 95, 98, ME). Look for the name of the driver, which will usually 
include the words PS/2 or IntelliMouse
To restore mouse operation when hot plugging:
1  Using a suitable SAM (Server Access Module) and category 5, 5e or 6 link 
cabling, carefully make the connections between the keyboard, monitor, 
mouse (and audio) sockets of the server and the required ServSwitch CX 
port.

3  Highlight ‘Functions’ and press

4  As appropriate, highlight one of the following options:
•  Restore Standard Mouse – if PS/2 mode is required, or   
•  Restore IntelliMouse – if IntelliMouse mode is required.
  Then press 
.
5  Move the mouse a short distance and check for appropriate on-screen 
cursor movement. If the mouse cursor darts erratically around the screen, 
then cease moving the mouse. This is an indication that the chosen restore 
function is incorrect. Try again using the other restore function.
Note: The restore functions predict the likely mouse resolution settings but 
may not restore the exact speed or sensitivity settings that were originally 
set.
