Chapter 2: Overview
2. Overview
2.1 Introduction
The 10-Gigabit Web Smart Switch - 10-Port is an affordable managed switch that provides a reliable infrastructure for your
business network. The switch delivers the intelligent features you need to improve the availability of your critical business
applications, protect your sensitive information, and optimize your network bandwidth to deliver information and applications
more effectively. Easy to set up and use, it provides the ideal combination of affordability and capabilities for entry-level
networking, including small business or enterprise applications.
The LGB5510A switch has 10 ports for 10-Gigabit Ethernet connectivity. However, unlike other entry-level switching solutions that
provide advance managed network capabilities only in the costliest models, the LGB5510A switch supports advanced security
management capabilities and network features, including data, voice, security, and wireless technologies. The switches are easy to
deploy and configure.
2.2 Features
• Has ten (8) 10-Gigabit twisted-pair ports and (2) slots for SFP+ modules.
• Supports data, voice, and wireless technologies.
• Easy to deploy and configure.
• Performs wire-speed, non-blocking switching to transport multiple packets at wire speed and low latency on all ports
simultaneously.
• All ports operate in full-duplex mode, which effectively doubles the bandwidth of each connection.
• Uses store-and-forward technology to ensure maximum data integrity. With this technology, the entire packet must be received
into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the
network.
• The switch can also be managed over the network with a web browser application.
NOTE: For a detailed description of the management features, refer to the user’s manual.

Chapter 3: Network Planning
3. Network Planning
3.1 Introduction to Switching
A network switch allows simultaneous transmission of multiple packets, and it can partition a network more efficiently than
bridges or routers. A switch is one of the most important devices for today’s networking technology.
When performance bottlenecks are caused by congestion at the network access point (for example, a file server), the device can
be connected directly to a switched port. Using full-duplex mode, the bandwidth of the dedicated segment will be doubled to
maximize throughput.
When networks are based on repeater (hub) technology, the distance between end stations is limited by a maximum hop count.
A switch subdividing the network into smaller and more manageable segments, and linking them to the larger network turns the
hop count back to zero and removes the limitation.
A switch can be easily configured in any Ethernet, Fast Ethernet, or Gigabit Ethernet network to significantly increase bandwidth
while using conventional cabling and network cards.
3.2 Application Examples
The LGB5510A Switch has eight 10-Gigabit Ethernet TP ports with auto MDI-X and two slots for removable SFP+ modules that
support comprehensive types of fiber connection, such as LC and BiDi-LC modules. It is not only designed to segment your
network, but also to provide a wide range of options in setting up network connections. Some typical applications are described
below.
The switch is suitable for the following applications.
• Enterprise or SMB remote sites.
• Peer-to-peer connecting two remote offices.
• Office network.
• High performance requirements environments.
• Advanced security for network safety applications.
• Data/voice and video conferencing applications.

Chapter 6: Making Network Connections
6. Making Network Connections
6.1 Connecting Network Devices
The switch is designed to be connected to 100M, 1G, 10Gbps network cards in PCs and servers, as well as to other switches and
hubs. It may also be connected to remote devices using optional SFP+ transceivers.
6.2 Twisted-Pair Devices
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category 6 or 6a cable for
10GBASE-T connections, and Category 6 or better for 1000BASE-TX connections.
6.3 Cabling Guidelines
The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, so you can use standard straight-through
twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).
CAUTION: Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with
RJ-45 connectors that conform to FCC standards.
6.4 Connecting to PCs, Servers, Hubs, and Switches
Step 1: Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.
Figure 6-1. Making twisted-pair connections.
Step 2: If the device is a network card and the switch is in the wiring closet, attach the other end of the cable segment to a
modular wall outlet that is connected to the wiring closet. (See the section “Network Wiring Connections.”) Otherwise, attach
the other end to an available port on the switch.
Make sure each twisted pair cable does not exceed 328 ft (100 meters) in length.
NOTE: Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise,
backpressure jamming signals may degrade overall performance for the segment attached to the hub.
6.5 Network Wiring Connections
A punch-down block is an integral part of equipment racks. It is actually part of the patch panel. Instructions for making
connections in the wiring closet with this type of equipment follow.
Step 1: Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel.
Step 2: If not already in place, attach one end of a cable segment to the back of the patch panel where the punch-down block is
located, and the other end to a modular wall outlet.
Step 3: Label the cables to simplify future troubleshooting. See Chapter 7, Cable Labeling and Connection Records.
