            Ordering Information

            Prevent costly network downtime with the reliable Pro Switching network backup switch from Black Box. Use this optical Layer 1 switching system to add network backup and failover switching to fiber connections on your data networks. It's ideal for mission-critical classified government and military networks, broadcast networks, private medical/healthcare systems, and factory/industrial applications.

            With the Pro Switching System 1U NBS, it's very simple to switch all users from a main network to a backup network. Locally, this is done using a momentary toggle switch on the chassis' front or from a serial RS-232 workstation. But it also supports control from a remote workstation via its 10BASE-T Ethernet port. Through this TCP/IP connection, you can switch and monitor circuits using Telnet, SNMP, or a Web browser link.
