Data Conversion between different Media types and Speed
The media converter supports the following conversions: z 1000Mbps (1000BASE-T) copper to/from 1000Mbps (1000BASE-X) fiber z 100Mbps (1000BASE-TX) copper to/from 1000Mbps (1000BASE-X) fiber z
10Mbps (10BASE-T) copper to/from 1000Mbps (1000BASE-X) fiber
Mini-GBIC (SFP) Fiber Connectivity
The mini-GBIC (SFP) port can be installed with different optional SFP optical fiber transceiver to support multimode or single mode fiber for short reach up to long reach distance.
Loopback Test Support
The media converter provides loopback 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
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 devices are connected with each other via fiber link. The device 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: z
Filtering all untagged packets z
Filtering all tagged packets z Filtering tagged packets with certain VID z Packet Tag removal (Untagging) z Packet Tag insertion (Tagging)

2.5 Making UTP Connections
The 10/100/1000 twisted-pair copper (TP) port supports the following connection types and distances:
Network Cables
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:
Model Methods
Unmanaged model DIP SW (switches) SW1, SW2, SW3
Managed model DIP SW (switches) SW1, SW2, SW3
Software management via web interface

3. Functions
To help a better understanding about the software management interfaces, this chapter describes some advanced functions provided by the media converter.
3.1 Abbreviation
TP Port : The twisted-pair copper port of the media converter device.
FX Port : The optical fiber port of the media converter device.
Ingress Port : Ingress port is the input port on which a packet is received.
Egress Port : Egress port is the output port from which a packet is sent out.
IEEE 802.1Q Packets : A packet which is embedded with a VLAN Tag field
VLAN Tag : In IEEE 802.1Q packet format, 4-byte tag field is inserted in the original Ethernet frame between the Source Address and Type/Length fields. The tag is composed of :
#of bits
Frame field
1 6 3 1 1 2
TPID User priority CFI VID
TPID : 16-bit field is set to 0x8100 to identify a frame as an IEEE 802.1Q tagged packet
User Priority : 3-bit field refer to the 802.1p priority
CFI : The Canonical Format Indicator for the MAC address is a 1 bit field.
VID : VLAN identifier, 12-bit field identifies the VLAN to which the frame belongs to.
Untagged packet : A standard Ethernet frame with no VLAN Tag field
Priority-tagged packet : An IEEE 802.1Q packet which VID field value is zero (VID=0)
In the device, this packet is also treated as untagged packet.
VLAN-Tagged packet : An IEEE 802.1Q packet which VID field value is not zero (VID<>0)
PVID (Port VID)
PVID is the default VID of an ingress port. It is used in 802.1Q filtering for untagged packets. It is also often used as [Default Tag - VID] for egress tagging operation.
DSCP : Differentiated Service Code Point, 6-bit value field in an IP packet
3.2 Converter Function
The device supports the following data conversions between fiber cable and twisted-pair Cat.5 (copper) cable:
The data rate on twisted-pair segment depends on the link speed finally established with the link partner.
-20-
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 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]
-21-
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 are displayed on the local LED indicators as follows:
Methods to enable the function
Hardware setting: DIP SW5 is set to ON position

3.5 802.1Q Control Function
802.1Q Control function allows to 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 -
Untag Only -
Tag Only -
Disable port ingress drop function
All incoming untagged packets and priority-tagged packets are dropped.
Only VLAN-tagged packets are admitted.
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
Enable
Disable
Disable
Disable
All packets are with no modification.
All packets are untagged in egress.
Disable
Enable

Enable
All packets are tagged in egress.
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
VLAN-tagged
Ingress port Default Tag
Received packet own tag
Disable No tagging is performed.
-23-
[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.
-24-
3.6 QoS Function
The device provides a powerful Quality of Service (QoS) function to guide the packet forwarding in four priority classes. The versatile classification methods can meet most of the application needs.
The function is useful for guiding the incoming traffic on high data rate port into low data rate port in priority. The following figure illustrates the QoS operation flow when a packet received on the ingress port until it is transmitted out from the egress port:
Since the media converter can support full wire speed conversion for 1000Mbps to 1000Mbps, QoS function is not essential for such application. It is suggested to disable the QoS function for 1000Mbps to 1000Mbps conversion.
-25-
3.6.1 Packet Priority Classification
Each received packet is examined and classified into one of four priority classes, Class 3, Class 2,
Class 1 and Class 0 upon reception. The device provides the following classification methods:
802.1p classification : use User Priority tag value in the received IEEE 802.1Q packet to map to one priority class
DSCP classification : use DSCP value in the received IP packet to map to one priority class
Port-based classification : used when 802.1p and DSCP are disabled or fail to be applied
They all can be configured to be activated or not. More than one classification methods can be enabled at the same time. However, 802.1p classification is superior than DSCP classification.
802.1p mapping tables : Each port has its own mapping table for 802.1p classification.
DSCP mapping table : Two ports share one DSCP mapping table for DSCP classification.
Default port priority : A port default priority class is used when port-based classification is applied
All configuration settings are in per port basis except that DSCP mapping table is global to all ports. A received packet is classified into one of four priority class before it is forwarded to an egress port.
3.6.2 Priority Class Queues
Each port in the device is equipped with four priority class egress queues to store the packets for transmission. A packet is stored into the class queue which is associated to the classified priority class.
For example, a packet is stored into Class 3 egress queue if it is classified as priority Class 3.
3.6.3 Egress Service Policy
Each port can be configured with an egress service policy to determine the transmission priority among four class queues. By default, higher class number has higher priority than the lower class numbers.
Four policies are provided for selection as follows:
•
Strict priority : Packets in high priority class queue are sent first until the queue is empty
•
Weighted ratio priority Class 3:2:1:0 = 4:3:2:1 : four queues are served in 4:3:2:1 ratio
•
Weighted ratio priority Class 3:2:1:0 = 5:3:1:1 : four queues are served in 5:3:1:1 ratio
•
Weighted ratio priority Class 3:2:1:0 = 1:1:1:1 : four queues are served equally
Strict priority policy lets high priority class queue is served first until it is empty. Lower priority queue may not get any service (or egress bandwidth) when higher priority traffic is heavy for long time. Three weighted ratio policies are provided to resolve such problem. Four class queues are served in weighted round robin basis. Every priority class can get a guaranteed ratio for the egress bandwidth.

3.7 SNMP Trap Function
SNMP trap function allows the device to send trap message to an SNMP trap host over SNMP protocol when the associated trap event occurs.
SNMP Trap settings
The settings are used to configure a trap host who can receive the SNMP trap message issued from a media converter device unit.
[SNNP Trap]
[Community Name]
[Trap IP Address]
Enable / disable SNMP trap function
The community string bound in a trap message
The IP address of the target SNMP trap host who is allowed to receive the traps.
SNMP Trap events
The following events are defined for generating a trap message when the event occurs on the unit.
z z z z z
The device boot up.
TP copper port link down
TP copper port link up (link recovery).
FX fiber port link down
FX fiber port link up (link recovery).
The following example illustrates an event of FX port link down occurs and is detected by the device.
Then, it generates a trap message to the SNMP trap host PC.

4. Web Management
The media converter features an http server which can serve the management requests coming from any web browser software over TCP/IP network.
Web Browser
Compatible web browser software with JAVA script support
Microsoft Internet Explorer 4.0 or later
Netscape Communicator 4.x or later
Set IP Address for the System Unit
Before the device unit can be managed from a web browser software, make sure a unique IP address is configured for the unit.
4.1 Start Browser Software and Making Connection
Start your browser software and enter the IP address of the unit to which you want to connect. The IP address is used as URL for the browser software to search the device.
URL : http://xxx.xxx.xxx.xxx/
Factory default IP address : 192.168.0.2
4.2 Login to the Device Unit
When browser software connects to the device unit successfully, a Login screen is provided for you to login to the device as follows:
The device will accept only one successful management connection at the same time. The other connection attempts will be prompted with a warning message.
A new connection will be accepted when the current user logout successfully or auto logout by the device due to no access for time out of 3 minutes. System Configuration is displayed after a successful login.

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:
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] settings 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] settings 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 operation
Disabled Ignore Accept untagged web packets
Enabled VID=0
Reply untagged packets
Accept untagged web packets
Enabled VID<>0
( 1 ~ 4095)
Reply untagged packets
Accept matched tagged web packets only
Reply tagged packets with the configured tag
Notes:
1. No matter how management VLAN is configured, login password authentication is still required.
2. Default [Management VLAN - VID] is equal to zero. It is allowed to access the device from any untagged PC web browser.
3. Most of the PCs are tag-incapable for LAN access. Be sure the rules are followed before setting [Management VLAN - VID] not equal to zero.

Enable - set to enable DSCP classification to the port for IP packets
Disable - DSCP classification is not applied to the port.
Default priority class, it is used when 802.1p and DSCP classifications are disabled. It is also used as default priority class for the received packet when both 802.1p and DSCP classification failed in classification.
Class 3 ~ Class 0 - priority class
Service policy for egress priority among four egress class queues
Strict priority - high class queue is served first always till it is empty
Ratio 4:3:2:1 - Weighted ratio priority Class 3:2:1:0 = 4:3:2:1
Ratio 5:3:1:1 - Weighted ratio priority Class 3:2:1:0 = 5:3:1:1
Ratio 1:1:1:1 - Weighted ratio priority Class 3:2:1:0 = 1:1:1:1
Click to configure 802.1p mapping tables.
Click to configure DSCP mapping table.
Click to apply the configuration change
Click to refresh current configuration
Notes:
1. 802.1p classification is superior over DSCP classification if both are enabled. That means if a received packet is classified successfully in 802.1p classification, the classified priority class is used directly for the packet and the result of DSCP classification is ignored.
2. Queue with higher class number has higher priority than queue with lower class number.
That means Class 3 > Class 2 > Class 1 > Class 0 by default.
3. In weighted ratio policies, a weighted fairness round robin service is guaranteed normally.
However, when excess bandwidth exists higher class queue will take advantage on bandwidth allocation.
4. It is suggested to apply QoS Control function only on 1000M to 100M conversion. Under
1000M to 1000M full wire speed conversion, the effect of QoS control function is not obvious.
