Black Box ServSwitch Secure and Secure PLus Manual Do Utilizador

®

Please consider the following important points when planning the location of 
the ServSwitch Secure unit:

•  Situate the unit close to the host computers to which it will be connected 

and also the user console peripherals. 

•  The unit requires a power supply input, so a nearby spare mains power 

outlet will be required. 

•  As keyboard and mouse switching codes are not possible for security reasons, 

the only way to change channels is via the front panel buttons. Therefore, the 
unit should be easily accessible from the user’s normal position.     

•  Please consult the precautions listed within the 

It is vitally important to use good quality shielded cables to minimise the 
risk of signal emissions that may be intercepted. Please follow the following 
recommendations when specifying cables: 

•  DVI cables - should be braid and foil shielded.  
•  VGA cables - should be braid and foil shielded. If DVI-I to VGA style adapters 

are used these should be of the fully ‘canned’ variety. 

•  USB cables - should be braid and foil shielded.  
•  Audio cables - should be braid shielded with fully shielded connectors (not 

unshielded connectors with drain wires). 

We strongly recommend that you fit ferrite cores at both ends of every cable to 
further assist with emission suppression. 

Given the high security nature of most installations that incorporate this unit, it 
may be a policy of your organisation to fit tamper-evident labels across certain 
seals and/or chassis screws. 
The unit assists in the use of tamper-evident seals in two ways:

•  All chassis retaining screws are countersunk so that their heads are flush 

with the outer covers, making it easy to apply seals across them.

•  The main cover is coated in a special matt finish that is particularly suited for 

contact with self-adhesive strip seals.

SECT 3

The rear panel of the unit is well marked, however, the diagram below offers 
additional clarity on how best to arrange your connections.
You may have noticed that the indicators on the front panel use different 
colors to represent the various channels. This is done to provide quick and 
effective visual feedback to the operator. Channel 1 has a green indicator 
and is traditionally used for the lowest security connection. The final channel, 
numbered 2 on the two port version and 4 of the four port version, uses a red 
indicator and is usually connected to the highest security connection. These are 
configuration conventions only and are offered as a suggestion - there are no 
technical differences in the operational specifications of the four channels.
