Our fast ethernet media converters provide an economical path to extend the distance of an existing network, the life of non-fiber based equipment, or the distance between two devices. Network Administrators can rest assured with Perle's advanced features such as Auto-Negotiation, AutoMDIX, Link Pass-Through, Far End Fault, and Pause which make the end to end link completely transparent. This allows for more efficient troubleshooting and less on-site maintenance. These cost and time saving features, along with a lifetime warranty and free worldwide technical support, make Perle's fast ethernet media converters the smart choice for IT professionals. Fast Ethernet Converter Features: 100Base-TX to 100Base-FX AutoNegotiation (802.3u) The media converter supports auto negotiation on the fast ethernet 100Base-TX interface. Auto-MDIX Auto-MDIX (automatic medium-dependant interface crossover) detects the signaling on the 100Base-TX interface to determine the type of cable connected (straight-through or crossover) and automatically configures the connection when enabled. With Auto-MDIX enabled, either a straightthrough or crossover type cable can be used to connect the media converter to the device on the other end of the cable. Link PassThrough With Link Pass-Through the state of the 100Base-TX receiver is passed to the 100Base-FX transmitter to make the media converter appear transparent to the end devices that are connected. In addition if Far-End Fault is enabled the media converter can turn off the 100Base-TX transmitter when a FAREnd Fault is received. Using Link Pass-Through with Far-End Fault minimizes data loss when a fault occurs. Should a fault occur, the end devices have the indication of a failure available to them making trouble shooting easier. 1/11 Far-End Fault (FEF) The media converter implements the 802.3 standard for Far-End Fault for the indication and detection of remote fault conditions on the 100Base-FX fiber connection. With Far-End Fault enabled the media converter transmits the Far-End Fault Indication over the 100Base-FX fiber connection whenever a receive failure is detected on the 100Base-FX fiber connection. The media converter continuously monitors the100Base-FX fiber connection for a valid signal. The action the media converter takes on receiving a Far-End Fault Indication is dependent on the Link Pass Through switch setting. Pause (IEEE 802.3xy) Pause signaling is an IEEE feature that temporarily suspends data transmission between two devices in the event that one of the devices becomes overwhelmed. The fast ethernet media converter supports pause negotiation on the 100Base-TX copper connection. VLAN The media converter is transparent to VLAN tagged packets. Power Input Supply Voltage 6 - 30 vDC, unregulated ( 12 vDC Nominal ) Current 167 mA Power Consumption 2.0 watts Power Connector 5.5mm x 9.5mm x 2.1mm barrel socket Power Adapter Universal AC/DC Adapter 100-240v AC, regulated DC adapter included Indicators Power / TST This green LED is turned on when power is applied to the media converter. Otherwise it is off. The LED will blink when in Loopback test mode. Fiber link on / Receive activity (LKF) This green LED is operational only when power is applied. The LED is on when the 100Base-FX link is on and flashes with a 50% duty cycle when data is received. Copper link on / Receive activity (LKC) This green LED is operational only when power is applied. The LED is on when the 100Base-TX link is on and flashes with a 50% duty cycle when data is received. 2/11 Switches - accessible through a side opening in the chassis AutoNegotiation (802.3u) Enabled (Default) - The media converter uses 802.3u Auto-negotiation on the 100Base-TX interface. It is set to advertise full duplex. Disabled - The media converter sets the 100Base-TX port to full duplex. Pause Pause should be enabled when all devices connected to the media converter support pause. Auto-Negotiation must be Enabled to use this feature. Enabled (Default) - The Media converter will advertise Pause capability during Auto-Negotiation on the 100Base-TX interface. Disabled - The Media converter will advertise that it does not have Pause capability during Auto-Negotiation on the 100Base-TX interface. Link Pass Through Enabled (Default) - When the state of the receiver is changed on the 100Base-TX interface it is reflected on the 100Base-FX fiber transmitter. When the state of the receiver on the 100Base-FX interface is changed it is reflected on the 100Base-TX transmitter. When a Far-End Fault Indication is received on the fiber interface the 100Base-TX transmitter is turned off. When the Far-End Fault Indication is cleared the transmitter is turned back on. Disabled - The 100Base-TX and the 100Base-FX fiber interface operate independently. Far-End Fault indication on the 100Base-FX fiber interface has no effect on the 100Base-TX interface. Far-End Fault (FEF) Enabled (Default) - The media converter transmits the Far-End Fault Indication over the 100Base-FX fiber connection whenever a receive failure is detected on the 100Base-FX fiber connection. The media converter continuously monitors the100Base-X fiber connection and clears the Far-End Fault Indication condition when a valid signal is received. Disabled - Far-End Fault Indications are not transmitted regardless of the condition of the receive signal on the 100Base-FX fiber connection. Remote Loopback The media converter can perform a loopback on the 100Base-X fiber interface. Disabled (Default - Up) Enabled - The 100Base-X receiver is looped to the 100Base-X transmitter. The 100Base-TX transmitter is taken off the interface. 3/11 Auto-MDIX (Internal Strap) If Auto-Negotiation (802.3u) is enabled, the media converter uses the HP Auto-MDIX method for the 100Base-TX interface. If Auto-Negotiation (802.3u) is disabled the Media converter will use the RX Energy method on the 100Base-TX interface to set the port MDI or MDIX whichever is appropriate. Enabled (Default) - Either a straight-through or crossover type cable can be used to connect the media converter to the device on the other end of the cable. Disabled - If the partner device on the other end of the cable does not have the Auto-MDIX feature a specific cable, either a straight-through or crossover will be required to ensure that the media convertor's transmitter and the partner devices transmitter are connected to the others receiver. The Media Convertor's 100Base-TX port is configured as MDI with this switch setting.
