1. Introduction
LevelOne media converters are Fast Ethernet 100Base-TX to
100Base-FX and 1000Base-T to 1000Base-SX/LX converters to
provide the flexibility required in network integration. The TX port
auto-sense connection speed, auto-negotiates half/full duplex
modes and auto-selects MDIX media type. The fiber connectors
come with multimode or singlemode, SC, ST or SFP connector to
provide necessary connection interface and distance capabilities.
LevelOne have designed 19” racks to organize media converters the
smart way by providing a single power supply. With the
Plug-and-play technology, the converter is easy to set-up and run.
For simple, cost-effective network design, LevelOne converter
series is the perfect solution to bridge the complex network
infrastructure.

2.4. DIP-switch
The DIP-switch is used to configure operation mode for LLF (Link
Lost Forwarding) and operation mode for UTP/Fiber port. The
default value of DIPswitch is OFF.

Link Lost Forwarding:
When LLF is enable, allow UTP link failures to be reported to the
fiber side and also allow Fiber link failure to be reported to the UTP
side. Therefore, A link loss forward feature is provided in both UTP
and Fiber side.
Pure Converter mode (Fast Ethernet Module):
When pure converter mode is enabling (on), it operates with the
minimum latency. The transmission flow does not wait until entire
frame is ready, but instead it forwards the received data immediately
after the data being received. And TP port should be forced at 100M
in this application. When DIP-Switch is in Switch Converter mode
(off), the converter function is same as Switch Hub.
Note:
Please don’t change the DIP-switch setting when UTP or fiber port is
transmitting or receiving data. It may cause some data error.
