Use this NBS008MA Layer 1 switching system to add network backup and failover switching to your data networks. It's ideal for mission-critical applications, including classified information and military systems, broadcast networks, and stock exchanges.
With the Pro Switching System 1U NBS, it's very simple to switch all users from the 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 the system's circuits using Telnet, SNMP, or a Web browser link. The switching system also features auto bypass and auto-recovery functions. If the "normal" network paths between the chassis and the device being monitored go down for any reason, the chassis will automatically switch from the normal connection state to the bypass, or failover, connection state.
This NBS008MA model switches four leads (Pins 1/2 and 3/6) on the RJ-45 ports. It's designed for use in 10BASE-T/100BASE-TX Ethernet, T1 circuit switching, and similar applications where no more than two pairs of leads are used. Each switching circuit has a common (C) port that's latched to its associated A or B port, which means it passes signals even if the chassis is without AC power. Because its relays are physically latched into position, once a position is set, it stays set. The switch circuit is as reliable as the CATx cables connected to it.
A key-lockable switch secures the gang switching function. With the key-lock switch in the enabled position, all ports in the Pro Switching System 1U NBS can be simultaneously switched by pressing the momentary toggle switch on the chassis' front. Port settings are also software controllable, so you can toggle a connected device from the A to the B position from a workstation. You not only have reliable network paths, but you can automate switching to control individual settings.
Need to add ports later? Simply daisy-chain multiple Pro Switching System 1U NBS chassis together - up to 255 in all - and control them as a single system.
