Page 9: Introduction
IP-based networks. The Hardened Industrial switch provides modern Ethernet connectivity for a variety of factory automation and SCADA applications. The Black Box LBH18x series Hardened switch provides eight 10/100 copper ports and one 100Mbps fiber up-link port. They are hardened to withstand the stress of industrial environments, highly reliable (over 25 years MTBF), and are easily fitted into industrial and telecom control cabinets. - Page 10 Models with a DIN- Rail mounting bracket included are available. The LBH08x/LBH18x industrial hardened switches and the other Black Box industrial networking products are backed by a three-year warranty. Industrial switches can connect a group of Ethernet-ready, process control units to a central control switch or to backhaul aggregated data from a cluster of edge switches that is typical in telecommunication environment.

Chapter 2: Introduction Fig 2.2a LBH082A-H and LBH182A-H-SC models shown 2.2.1 LBH18x chassis with SC or LC Fiber port The LBH18x chassis houses one main PC board. The front side of the chassis has eight RJ-45 twisted-pair ports and one 100Mbps fiber port, located at the left front of the unit. -
Page 12: Fiber Port, Sc Or Lc Connector For Model Lbh18X
Chapter 2: Introduction Fiber port, SC or LC Connector for Model LBH18x The Fast Ethernet fiber port on the LBH18x is set to operate at fixed 100Mbps speed for guaranteed high performance. The LBH18x fiber port is factory- built as either a multi-mode SC, LC or single-mode SC or LC connector. The 100Mbps fiber port will run at 100Mbps speed at all times. - Page 13 Chapter 2: Introduction When the Switch detects that its free buffer queue space is low, the Switch sends industry standard (full-duplex only) PAUSE packets out to the devices sending packets to cause “flow control”. This tells the sending devices to temporarily stop sending traffic, which allows a traffic catch-up to occur without dropping packets.

They perform high speed filter/forward operations on the traffic, giving each port’s segment a full 100Mbps (or 10 Mbps) of bandwidth. Option for one “future-proof”... -
Page 15: Applications
Chapter 2: Introduction Applications The LBH08x and LBH18x are designed to bring future-proof fiber connectivity and widely- used copper connectivity to factory automation control systems, field bus control systems and many other industrial network environments. Ethernet networks in factory control systems provide interoperability and bandwidth with universal connectivity via 10/100 RJ-45 ports, all at an economical cost. - Page 16 Chapter 2: Introduction Where there are existing 10 Mbps hubs or switch users, they can easily be cascaded into any port of the LBH18x. This allows a simple plug-and-play addition of 100Mbps ports to an existing 10 Mbps network without having to change it. Nodes that are capable of 100Mbps speed can be moved to a LBH18x port, and will automatically operate at the higher speed.

Page 17: Installation
Chapter 3: Installation INSTALLATION Before installing the equipment, it is necessary to take the following precautions: If the equipment is mounted in an enclosed or multiple rack assembly, the steady-state long-term environmental temperature around the equipment must be less than or equal to 60 If the equipment is mounted in an enclosed or multiple rack assembly, adequate airflow must be maintained for proper and safe operation. - Page 18 Chapter 3: Installation Note: The metal brackets supplied, hold the back of the switch out from the panel or wall behind it, creating a rear space of about 1/8 inch or 3mm. This allows air circulation and cooling of the rear part of the case. For best cooling of the switch, attach the metal brackets to metal (rather than wood or plastic).
