Chapter 1: Overview
1.2 Switch Architecture
The switch operates at wire-speed, transporting multiple packets at low latency on all ports simultaneously. The switch also
operates at full-duplex, which effectively doubles the bandwidth of each connection.
For maximum data integrity, the switch uses store-and-forward technology. With this technology, the entire packet is received into
a buffer and checked for validity before it is forwarded. This prevents errors from being propagated throughout the network.
1.3 Network Management Options
You can also manage the switch over the network via a Web browser or Telnet. The switch includes a built-in network
management agent that allows it to be managed in-band using SNMP or RMON (Groups 1, 2, 3, 9) protocols. It also has an
RS-232 DB9 console port connector on the front panel for out-of-band management. A PC may be connected to this port for
configuration and monitoring out-of-band via a null-modem serial cable. (See Appendix B for wiring options.)
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.
When performance bottlenecks are caused by congestion at the network access point such as file server, the device can be con-
nected directly to a switched port. In full-duplex mode, the bandwidth of the dedicated segment can 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 can subdivide the network into smaller and more manageable segments, and link them to the larger network.
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 Gigabit PoE+ Ethernet Managed Switch Eco LPB5028A has 24 Gigabit Ethernet twisted-pair ports with auto MDI-X and 4
slots for removable SFP modules that support LC and BiDi-LC fiberoptic modules. The LPB5052A has 48 Gigabit Ethernet twisted-
pair ports with auto MDI-X and 4 SFP module slots. The switch not only segments your network, but also provides a wide range
of options in setting up network connections. Some typical applications are described below.
The switch is suitable for the following applications:
• Remote site application for Enterprise or SMB.
• Peer-to-peer application for two remote offices.
• Office network
• High-performance Requirement environment
• Advanced security for network safety application.
• Suitable for data/voice and videoconferencing application.

Step 1. Insert the power cable plug directly into the AC socket located on the back of the switch.
Step 2. Plug the other end of the cable into a grounded, 3-pin, AC power source.
Step 3. Check the front-panel LEDs as the device is powered on to be sure the Power LED is lit. If not, check that the power cable
is correctly plugged in.
WARNING: For international use, you may need to change the AC line cord. You must use a line cord set that has been approved
for the socket type in your country.
4.7 Connecting to the Console Port
The DB9 serial port on the switch’s front panel connects to the switch for out-of-band console configuration. You can access the
command-line-driven configuration program from a terminal or a PC running a terminal emulation program.
The pin assignments used to connect to the serial port are provided in Table 4-2.
Figure 4-8. Serial port (DB9 DTE) pinout.
The DB9 cable is used to connect a terminal or terminal emulator to the switch’s RS-232 command-line interface.
