Rev.1.0
2005/1/27

1. Introduction
The LB-FEA800M is compact desktop size switches that are ideal solutions
for SOHO (Small Office or Home Office) network user. It provides wire-speed,
Fast Ethernet switching function that allows high-performance, low-cost
connection. The Switches feature a store-and-forward switching and it can
auto-learn and store source address on an 8K-entry MAC address table.
The Switches provides 8 switched auto-sensing 10/100 Mbps RJ-45 Ethernet
ports and features Auto MDI/MDIX function for each port. [In general, MDI
means connecting to another Hub or Switch while MDIX means connecting to
a workstation or PC. Therefore, Auto MDI/MDIX means that you can connect
to another Switch or workstation without changing non-crossover or crossover
cabling. ]
With there build-in Web-based Management, managing and configuring the
LB-FEA800M becomes easier. From cabinet management to port-level control
and monitoring, you can visually configure and manage your network via Web
Browser. Just click your mouse instead of typing command strings. However,
the LB-FEA800M can also be managed via Telnet, Console, or SNMP
Management.

Ethernet Switching Technology
Ethernet Switching Technology dramatically boosted the total bandwidth of a
network, eliminated congestion problems inherent with Carrier Sense multiple
access with Collision Detection (CSMA/CD) protocol, and greatly reduced
unnecessary transmissions.
This revolutionized networking. First, by allowing two-way, simultaneous
transmissions over the same port (Full-duplex), which essentially doubled the
bandwidth. Second, by reducing the collision domain to a single switch-port,
which eliminated the need for carrier sensing. Third, by using the
store-and-forward technology’s approach of inspecting each packet to
intercept corrupt or redundant data, switching eliminated unnecessary
transmission that slow the network. By employing address learning, which
replaced the inefficient receiving port.
Auto-negotiation regulates the speed and duplex of each port, based on the
capability of both devices. Flow-control allows transmission from a 100Mbps
node to a 10Mbps node without loss of data. Auto-negotiation and flow-control
may require disablement for some networking operations involves legacy
equipment. Disabling the auto-negotiation is accomplished by fixing the speed
or duplex of a port.

Ethernet Switching Technology supplied higher performance at costs lower
than other solutions. Wider bandwidth, no congestion, and the reduction in
traffic is why switching is replacing expensive routers and inefficient hubs as
the ultimate networking solution. Switching brought a whole new way of
thinking to networking.

Management Methods
The LB-FEA800M series supports following management methods:
nConsole and Telnet Management
nWeb-based Management
nSNMP Network Management
Console and Telnet Management
Console Management is done through the RS-232 Console Port. Managing
the LB-FEA800M in this method requires a direct connection between PC and
the 8TP+1Fiber Management Switch. While Telnet management is done over
the network. Once the LB-FEA800M is on the network, you can use Telnet to
Log in and change the configuration.
Web-based Management
The Switch provides an embedded HTML web site residing in flash memory. It
offers advanced management features and allow users to manage the
LB-FEA800M from anywhere on the network through a standard browser such
as Microsoft Internet Explorer.
SNMP Network Management
SNMP (Simple Network Management Protocol) provides a means to monitor
and control network device, and to manage configurations, statistic collection,
performance, and security.

2. Hardware Description
This section mainly describes the hardware of the LB-FEA800M.
Physical dimensions
The physical dimensions of the LB-FEA800M is 250mm x 133mm x 37mm (L
x W x H)
Front Panel
The Front Panel of the LB-FEA800M consist of 8x auto-sensing 10/100Mbps
Ethernet RJ-45 ports (automatic MDI/MDIX) and the LED indicators are also
located on the frond panel of the switch.

nRJ-45 Ports (Auto MDI/MDIX): 8x 10/100 auto-sensing for 10Base-T or
100Base-TX connections.
[In general, MDI means connecting to another Hub or Switch while MDIX
means connecting to a workstation or PC. Therefore, Auto MDI/MDIX
means that you can connect to another Switch or workstation without
changing non-crossover or crossover cabling. ]

LED Indicators
There are three LED-Indicators (100M, LNK/ACT, FDX/COL) for each UTP
port. The following table provides descriptions of the LED statuses and
meaning. They provide a real-time indication of systematic operation status.
