Black Box ServSwitch CX 用户手册

®

The ServSwitch CX provides an autoscan mode that switches between 
the connected servers in sequence. This mode is useful to allow users and 
administrators to sample activity among the connected machines. Three 
scanning modes are provided:

•  Scan list – Only servers declared within an autoscan list will be viewed. 

Servers connected to cascaded switches can be included in the autoscan list.

•  Active PCs – Only computer ports where an active server is detected will be 

viewed. This mode avoids blank screens from being displayed and helps to 
prevent the viewing monitor from entering a power-down state on every 
scan cycle. Servers connected to cascaded switches will not be viewed in this 
mode.

•  All PCs – This mode visits, in turn, each server that is connected directly to 

the ServSwitch CX. This mode should be used with care due to the reasons 
given in the warning below. Servers connected to cascaded switches will not 
be viewed in this mode.

The scanning mode is a global setting and hence will be the one viewed by any 
user who selects 

 

   on their keyboard. Note, however, that users will 

only see the scanned servers to which they have access rights. Hence, if two 
users (with various access rights) simultaneously view an autoscan, they will see 
differing results depending upon their respective permissions.
WARNING: Many monitors are fitted with automatic power saving relays 
that switch off after a few seconds when connected to an inactive server. 
If you are using such a monitor, do not set the ServSwitch CX to the scan 
‘ALL PCs’ mode. Continual switching on and off of the monitor’s relay will 
eventually damage the monitor. If using such a monitor in conjunction 
with the ‘Scan List’ option, ensure that all selected servers are active.
There are up to three steps that need to be configured to use autoscanning 



•  Select the autoscan mode: Scan List, Active PCs or All PCs.
•  Select the autoscan period. This is the time that is spent viewing each server. 

This step also enables and disables the autoscan feature.

•  Define the autoscan list. This step is only required when the Scan List option 

is selected and allows you to select which servers will be scanned.
