1. Introduction

The device is a Gigabit Ethernet media converter series which provide the following features:

Data Conversion between different Media types and Speed

The media converter supports the following conversions:

 1000Mbps (1000BASE-T) copper to/from 1000Mbps (1000BASE-X) fiber
 100Mbps (1000BASE-TX) copper to/from 1000Mbps (1000BASE-X) fiber
 10Mbps (10BASE-T) copper to/from 1000Mbps (1000BASE-X) fiber
 1000Mbps (1000BASE-T) copper to/from 100Mbps (100BASE-FX) fiber
 100Mbps (1000BASE-TX) copper to/from 100Mbps (100BASE-FX) fiber
 10Mbps (10BASE-T) copper to/from 100Mbps (100BASE-FX) fiber

Dual-speed Fiber Connectivity

The converter is featured with two different SFP slots. One is designed for accommodating Gigabit Ethernet
1000BASE-X optical fiber transceiver and the other is designed for accommodating Fast Ethernet
100BASE-FX optical fiber transceiver. Each SFP can be installed with variety of optional transceivers
supporting multimode or single mode fiber for short reach up to long reach distance.

Power over Ethernet support

The copper port is featured Power over Ethernet (PoE) function. With proper 48VDC power supply, it is able
to deliver power to one PoE powered device (PD) via Cat.5 cable together with LAN data.

Loop-back Test Support

The media converter provides loop-back test function which can verify the fiber link with its link partner by
sending test packets to the link partner and verifying the echo packets sent back. This feature is helpful in
checking connection quality of fiber link during installation.

Link Fault Pass-Through

-6-

This feature can force the link to shut down as soon as it notices that the other link has failed. It allows a link
partner on one cable segment can notice a link fault occurred on the other segment and give application a
chance to react.

Remote TP Port Status Monitoring

When two converters connected with each other via fiber link, the converter can monitor and display the
twisted-pair port status of the remote fiber link partner. The status display can be on the local LED indicators or
web management interface.

802.1Q Control

With software configuration support, the device is enhanced with more 802.1Q control features for VLAN
applications rather than just a typical media converter function.

The optional features include:

 Filtering all untagged packets
 Filtering all tagged packets
 Filtering tagged packets with certain VID
 Packet Tag removal (Untagging)
 Packet Tag insertion (Tagging)

Quality of Service

For conversion between two different speeds, the device is featured with powerful Quality of Service (QoS)
function which can classify the priority for received network frames based on the ingress port and frame
contents. Furthermore, many service priority policies can be configured for egress operation.

Web Management

The device is embedded with an Http server which provides management functions for advanced network
functions including Port Control, Quality of Service, and Virtual LAN functions. The management can be
performed via Web browser based interface over TCP/IP network.

-14-

The following figure illustrates the converter is installed with Din-Rail mounting bracket:

2.4 Applying Power

Before you begin the installation, check the AC voltage of your area. The AC power adapter which is used to
supply the DC power for the unit should have the AC voltage matching the commercial power voltage in your
area.

The AC Power Adapter Specifications

Rated input voltage: 100~240 VAC
Rated input frequency: 50/60Hz
Output voltage: 56VDC (+1%/-3%)
Output current: 1.16A max.
Power cord: De-attachable IEC320 AC power cord

Steps to apply the power to the device are:

1. Connect power adapter DC plug to the DC input jack located on the back of the unit before connecting to

the AC outlet.

2. Connect the power adapter to the AC outlet.

3. Check Power LED indication.

2.5 Making UTP Connections

The 10/100/1000 twisted-pair copper (TP) port supports the following connection types and distances:

Network Cables

-15-

10BASE-T: 2-pair UTP Cat. 3,4,5 , EIA/TIA-568B 100-ohm
100BASE-TX: 2-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
1000BASE-T: 4-pair UTP Cat. 5 or higher (Cat.5e is recommended), EIA/TIA-568B 100-ohm
Link distance: Up to 100 meters

Auto MDI/MDI-X Function

This function allows the port to auto-detect the twisted-pair signals and adapts itself to form a valid MDI to
MDI-X connection with the remote connected device automatically. No matter a straight through cable or
crossover cable is connected, the ports can sense the receiving pair automatically and configure itself to match
the rule for MDI to MDI-X connection. It simplifies the cable installation.

Auto-negotiation Function

The port is featured with auto-negotiation function and full capability to support connection to any Ethernet
devices. The port performs a negotiation process for the speed and duplex configuration with the connected
device automatically when each time a link is being established. If the connected device is also
auto-negotiation capable, both devices will come out the best configuration after negotiation process. If the
connected device is incapable in auto-negotiation, the port will sense the speed and use half duplex for the
connection.

Port Configuration Management

For making proper connection to an auto-negotiation INCAPABLE device, it is suggested to set port
configuration to one of non-auto (forced) operating modes and specify speed and duplex mode which match the
configuration used by the connected device.

Two methods for setting copper port configuration are as follows:

The data rate on twisted-pair segment depends on the link speed finally established with the link partner.

3.3 Link Fault Pass Through Function

Description

When the Link Fault Pass Through (LFPT) function is enabled and the media converter detects a link fault on
one port segment, it will force the other port segment link down. It looks like that a link fault is passed from
one port to the other.

The following example illustrates a link fault occurs on the fiber cable (any one cable in a duplex fiber
connection). The link fault is forwarded to both Gigabit link partners finally by LFPT operation of two media
converters.

Both Gigabit devices will also detect a link fault on each Cat.5 connection, although the real fault occurs on the
fiber connection exactly.

The following example illustrates a real link fault occurs on one Cat.5 and the link fault is passed to the other
Cat.5 over two converters and the fiber cable by LFPT operation. Finally, the other link partner also detects a
link fault.

Advantage

The function allows two remote link partners of the media converters detect the link fault finally no matter
where the exact fault occurs. It allows the upper application takes necessary action in case a real link fault

-23-

occurs in any cable segment.

Methods to enable the function

The LFPT function can be enabled by:

Hardware setting: DIP SW6 is set to ON position
Software setting: Web management ->

Configuration -> System -> [Link fault pass through]

3.4 Remote TP Status Monitoring Function

Description

The local media converter can monitor the TP port link status of its remote link partner connected on the fiber
cable. The status is displayed on the local LED indicators as follows:

Methods to enable the function
Hardware setting: DIP SW5 is set to ON position
Software setting: Web management ->

Configuration -> System -> [Remote TP auto report]

Remote TP Status Display

1. The status is displayed on local LEDs i.e. TP1G, TP100, TP10, TPFDX when LTP is OFF.

2. Web management -> Monitoring -> Statistics -> Remote TP [Link]

3.5 802.1Q Control Function

802.1Q Control function allows perform 802.1Q VLAN related operation to the packets passing through the
media converter according packet contents as follows:

[Ingress Drop] setting

The setting is the first filtering mechanism to filter all incoming untagged packets or to filter all incoming
VLAN-tagged packets. The options are:

Disable - Disable port ingress drop function
Untag Only - All incoming untagged packets and priority-tagged packets are dropped.

Only VLAN-tagged packets are admitted.
Tag Only - All incoming VLAN-tagged packets are dropped.
Only untagged packets and priority-tagged packets are admitted.

[Ingress Keep Tag], [Egress Insert Tag] settings

The settings are used together for packet egress tagging or untagging as table listed below:

Ingress Keep Tag

Egress Insert Tag Packet Modification

-25-

Enable Disable All packets are with no modification.
Disable Disable All packets are untagged in egress.
Disable Enable All packets are tagged in egress.
Enable Enable Settings not recommended (possible double-tagging)

[Ingress Keep Tag] options:

Enable - The VLAN tag in the received VLAN-tagged packet will be kept as it is and is not

stripped in whole conversion operation.

Disable - The VLAN tag data in the received VLAN-tagged packet is stripped (removed).

[Egress Insert Tag] options:

Enable - Insert a tag into the packet in egress. The tag inserted is based on the rule below:
Incoming Packet Type

Tag inserted

Untagged Ingress port Default Tag
Priority-tagged Ingress port Default Tag
VLAN-tagged Received packet own tag
Disable - No tagging is performed.

[Default Tag -VID], [Default Tag - CFI], [Default Tag - Priority] settings

These settings compose one ingress port Default Tag. This tag is used when a tag insertion is required for
untagged packets.

802.1Q Filtering

802.1Q VID Filtering function allows to admit or reject certain VID tagged packets. Up to 16 allowed
(positive list) or rejected (negative list) VIDs can be configured. This function allows to limit certain packets to
pass from one link segment to another one.

[VID Table] options

Disable - 802.1Q VID filtering is disabled.
Allowed VID - Only the VLAN-tagged packets with VIDs in VID table are admitted.
Rejected VID - The VLAN-tagged packets with VIDs in VID table are rejected and dropped.

For untagged and priority-tagged packets, the ingress [Default Tag - VID], also called PVID is used for VID
filtering. If it is in Allowed VID table, the untagged packet is allowed to pass; otherwise, dropped. If it is in
Rejected VID table, the untagged packet is dropped.

4.4.1 Management VLAN

Management VLAN settings allow administrator to access the device and perform the web management over a
dedicated VLAN only.

The following rules are applied with the Management VLAN:

-33-

1. If the 802.1Q Control function is disabled, Management VLAN settings are ignored and no VLAN

limitation is applied in accessing the web management interface. The http server only accepts untagged
management packets and replies untagged packets to the management host.

2. If [Management VLAN - VID] setting is zero, no VLAN limitation is applied in accessing the web

management interface. The http server only accepts untagged management packets and replies untagged
packets to the management host.

3. If [Management VLAN - VID] setting is not zero, the http server only accepts tagged management packets

matched [Management VLAN -VID] and replies tagged packets with tag composed of [Management
VLAN] VID, CFI and User Priority settings to the management host.

Summary of the rules:

802.1Q Control

Management VLAN VID Embedded Http (Web) Server opera tion
