Page 20: Product Description
Chapter 2: Introduction Product Description 2.2.1 LBH21-Series Product Description The latest technology of SFP fiber transceivers has been integrated into the LBH21-Series Universal Converter Switch package. It can handle any Gb fiber type – multi-mode and single-mode – and fiber media distance with a selection of Gb SFP fiber transceivers, up to two of which can be plugged in. - Page 21 Chapter 2: Introduction No internal airflow is required for cooling, so it resists dust, dirt, moisture, smoke and insects. Mounting options include stand-alone panel mounting, DIN-Rail, or rack-mount tray. The LBH21xA-P Extreme-rated units are for temperature uncontrolled applications (-40 to 75° C), typically located outdoors. The Extreme (-P) models are built with premium-grade extended temperature components, and use similar thermal techniques as the Hardened units.
- Page 22 Chapter 2: Introduction Fig 2.2.1a LBH210A-H with two SFP slots The “Hardened” labeled LBH21-Series units (as shown in Fig 2.2.1a) are designed for office and wiring closet environments and factory floor/Industrial applications. Using special thermal techniques and a sealed rugged metal case for heavy- duty industrial applications no air inflow is required for cooling, so the LBH21-Series resist dust, dirt, moisture, smoke and insects.
- Page 23 Chapter 2: Introduction Fig 2.2.1b LBH210A-P with two SFP slots The “Extreme” labeled LBH21-Series (as shown in Fig. 2.2.1b) are premium rated units suitable for temperature uncontrolled outdoor applications. Specially designed with premium- grade extended temperature components, the LBH21xA-P units use similar thermal techniques to the LBH21xA-H hardened units for cooling.

Page 24: Frame Buffering And Latency
Chapter 2: Introduction The front side of the unit has one twisted-pair 10/100/1000Mb switch port and two 100 or 1000Mb fiber ports. The RJ-45 port of the LBH21-Series Converter switches support auto cross (MDI-X) operation performing the autocross function under auto-negotiation mode only. The LBH21 models are factory configured at Full Duplex. - Page 25 Chapter 2: Introduction collisions, to be forwarded to add to the network traffic. Since there is no way to filter frames with a bad CRC (the entire frame must be present in order for CRC to be calculated), the result of indiscriminate cut-through forwarding is greater traffic congestion, especially at peak activity.
- Page 26 Chapter 2: Introduction Another feature implemented in LBH21-Series Converter Switches is a collision-based flow-control mechanism (when operating at half-duplex only). When the Switch detects that its free buffer queue space is low, the Switch prevents more frames from entering by forcing a collision signal on all receiving half-duplex ports in order to stop incoming traffic.

Page 29: Applications For Lbh210-Series Converter Switches
The edge-of-the-network connectivity solutions offered by Black Box Converter Switches are focused on providing easier, more economical and ultra-reliable industrial application products. The compactly designed LBH21-Series act as very useful tools in the modern life of fast expanding network requirements. - Page 30 Chapter 2: Introduction Example 1: In this application, where in expanding an industrial network environment, the new PLC units are deployed on an existing network and each needs one (or two for redundancy) Ethernet ports to carry status and control data to the control center the hardened version of LBH21 is typically used.
- Page 31 Chapter 2: Introduction Example 2: LBH21-Series “Drop & Add” capability In this example, LBH21-Series Converter Switches form a gigabit backbone LAN with a “Drop & Add” capability that enables connecting many disparate devices in a fiber-media string, covering even very long distances (for example, a pipeline). Such designs are easily extended or expanded as conditions and devices needing network attachment change over time.

Page 44: Operation
Chapter 4: Operation OPERATION Triple-Speed Functionality, and Switching The LBH21-Series Converter Switches provide three switched ports. The architecture supports a triple speed-switching environment, with standard auto-negotiation capability. The switched RJ-45 ports are full- or half-duplex auto-sensing for mode and speed, and auto cross for plug polarity. (See Section 2.2). When the connected device is 10 Mbps, the LBH21-Series switch obeys all the rules of 10-Mbps Ethernet configurations. -
Page 45: Auto-Cross (Mdi-X), Auto-Negotiation And Speed-Sensing
Chapter 4: Operation Switching, Address Learning The LBH21-Series units have address table capacity of 1K node addresses, and are suitable for use in large networks. They are self- learning, so that as nodes are added or removed or moved from one segment to another, the LBH21-Series switch automatically keeps up with node locations. -
