physically secure environment along with the TLX Matrix Switch, the computer server used to manage
the Switch, and the Network Hub. The Network Hub is a dedicated network used only to connect the TLX
Switch to the computer server. This dedicated network does not connect to any other components and
does not extend beyond the physically secure environment. The dedicated network connection may be
replaced by a direct serial connection (RS-232) between the TLX Switch and the computer server.
The TLX Matrix Switch can be configured to
prevent accidental connection from the Red
Network to the Black Network using the
Restricted Switching feature.
