Use this Layer 1 switching system to add network backup and failover switching to 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 at the chassis itself using a momentary toggle switch on the front or via a serial RS-232 workstation.
Option with management over the network
The managed models also support 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.
These switching systems 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.
Available for copper or fibre connections
The Pro Switching System is available in a network managed as well as a non managed version. Choose from four or six multimode fibre ports and 8 or 16 copper ports.
Fibre versions (NBS004 and NBS006)
Unique latching optical switch mechanisms and micro-mirrors optically route signals between ports. And because the system is fibre based, , there's no need to worry about EMI/RFI interfering with signaling in electronically noisy applications.
The system uses duplex SC connections for each channel (port) to form bidirectional data paths to your 62.5/125-m multimode network segments. Simply connect fiber cables between the system's circuits and the network connections you want to control. As soon as the fiber cables are plugged into the chassis, the selected data paths become active.
Copper versions (NBS008, NBSAll8, and NBS016)
These models switch four leads (Pins 1/2 and 3/6) on the RJ-45 ports. They are 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.
For the use in 10BASE-T/100BASE-TX/1000BASE-TX Ethernet networks, and switching RS-232 circuits that use both data and hardware handshake leads, or any application that requires use of more than four leads, choose the NBSALL8 and NBSALL8MA. These models switch all eight leads on the RJ-45 ports.
Switching Circuits
Each switching circuit has a common (C) port that's latched to its associated A or B port, which means it transmits 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.
Key-lockable
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.
Software-Controllable Port Settings
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.
System Expansion
Need to add ports later? Simply daisychain multiple Pro Switching System 1U NBS chassis together—up to 255 in all—and control them as a single system.
