Page 20: Product Description
Chapter 2: Introduction Product description LPH240A Industrial PoE switch is a reliable and premium-rated Industrial Ethernet product Switch. Strictly designed to be IEEE 802.3af compatible, the 4-port PoE Edge switch, not only provides PoE options on port #3, 4, 5 and 6 but is also equipped with a LLL (Link-Loss-Learn) feature on port #1 and 2 for use in self-healing redundant LAN structures. - Page 21 Chapter 2: Introduction The LPH240A switch ports follow an auto-sensing algorithm, so that they provide power only to 802.3af, PoE end devices. PoE is managed by a multi-stage handshake to protect equipment from damage and to manage power budgets. The LPH240A ports will discontinue supplying power when the PoE powered devices are disconnected (on incorrect impedance value).
- Page 22 Chapter 2: Introduction These are applications where the LPH240A can be used to provide the power and data for these PoE Powered Devices, which require 12-13 watts maximum. - Wireless LAN access points and WLAN Mobility system - VOIP phones - Remote Security Camera - SNTP Clock - Factory floor and building control monitoring...

Page 23: Frame Buffering And Latency
Chapter 2: Introduction The LPH240A(PoE) Switch provides edge access Ethernet ports in a convenient and compact package. For fiber connectivity of additional non-PoE ports, simply use port#1 and 2 (two RJ-45 or 100 Mb fiber ports with LLL feature) to meet the Fiber and copper 10 or 100 Mb requirements. - Page 24 Chapter 2: Introduction There is no way to filter frames with a bad CRC (the entire frame must be present in order for CRC to be calculated). Since collisions and bad packets are more likely when traffic is heavy, store-and-forward switch technology enables more bandwidth to be available for good packets when the traffic load is greatest.
- Page 25 Chapter 2: Introduction Another feature implemented in LPH240A Series Edge 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 26: Features And Benefits
Chapter 2: Introduction Features and Benefits Full 100Mb or 10 Mb switching services for high performance Ethernet LPH240A Series PoE Switches provide Fast Ethernet switching on all ports. They perform high speed filter/forward operations on the traffic, giving each port’s segment a full 100Mb (or 10 Mb) of bandwidth. - Page 27 Chapter 2: Introduction Installation is “Plug and Play”, operation is transparent to software The LPH240A Series PoE Switches operate as hardware switches, only forwarding those packets from each domain that are needed on the other domains. Internal address tables are self-learning, enabling users to change port connections or 10/100 domains without affecting operations.
- Page 28 Chapter 2: Introduction MDIX ports to eliminate cross-over cables while cascading All the LPH240A Series Switches are featured with MDI-X (auto- cross), which easily allows cascading with other Switches, Hubs or media Edges without using the cross-over cable. DC-Power input for PoE Power Source Switch The 802.3af PoE standard power source switch requires 1.4 Amp- 48VDC to provide enough power for 13-15watts on each RJ-45 port.

Page 44: Operation
Chapter 4: Operation OPERATION Dual-Speed Functionality, and Switching The LPH240A Series Edge Switches provide SIX switched ports with combination of fiber and copper or copper only. The architecture supports a dual 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. - Page 45 Chapter 4: Operation Switching, Filtering and Forwarding Each time a packet arrives on one of the switched ports, the decision is taken to either filter or to forward the packet. Packets whose source and destination addresses lie on the same port segment will be filtered, constraining them to one port and relieving the rest of the network from processing them.
