12 Making connectionsConnections to the AdderView Secure unit do not need to follow the preciseorder given in this user guide, although if one or more systems must be hot-plugged, connect these after all other connections have been made.IMPORTANT: To achieve the high levels of signal isolation and low emissionsprofile that the switch is capable of delivering, it is necessary to use the only thecables listed in the Additional items section. These have been very carefullydesigned and tested to maximize the performance levels of the switch.Note: For additional security, use tamper-evident tape to bridge the computercable connections to the switch’s case once installed.Connections to computer systemsAll connections to computer systems are achieved using combined shielded linkcables of which there are several different types to suit the various ports used -see the Additional items section for details.See also Devices used with the AdderView Secure for advice about linkingdevices to the AdderView Secure unit.To connect a system link1 Wherever possible, ensure that power is disconnected from the unit and thehost computer(s) to be connected.2 At the rear panel of the unit, connect the appropriate link cable to the 26-way connector of the appropriate channel.Connections to user console peripheralsTo connect a keyboard and mouseIMPORTANT: To reduce the risk of radiated snooping, do not use wirelesskeyboard or mouse devices.See also Devices used with the AdderView Secure for advice about linkingdevices to the AdderView Secure unit.1 Wherever possible, ensure that power is disconnected from the unit and thehost computer(s) to be connected.2 In the middle of the rear panel, connect the cables from the keyboard andmouse to the USB sockets marked and respectively.Note: If using a combined keyboard and smartcard reader then connect thekeyboard/reader to the socket labeled . Any keyboard connected to thekeyboard socket should then be removed as it will become non-functional).3 Attach the connectors at the other end of the link cable to the appropriateports of the computer, i.e. VGA video, USB (or PS/2 keyboard and mouse)and the smart card reader, if used - see below.IMPORTANT: If only certain computers require the use of the smart cardreader, for those systems use a link cable that has only one USB connector -do not leave a spare USB link unconnected.CONSOLE3 If using a smart card reader, connect the cable from the reader to the USBsocket labeled .Note: The smartcard port is not active on standard models (AVSV1002-XXand AVSV1004-XX) which do not contain smartcard circuitry.
