S-110Pp-S2St20 Media Converter

This green LED is turned on when power is applied to the media converter. Otherwise it is off. The LED will blink slowly when either fiber port is in Loopback test mode. The LED will blink quickly if there is a hardware failure where the reason code can be identified through a various blinking cycles.

This LED will signify the status of the PSE function. Using multi-color and blinking the unit will show the following status for the PSE; GREEN - Solid: The PSE has successfully detected a compliant PD and is applying power over the UTP (for legacy pin out simply show active power when applied); YELLOW - Solid: The PSE is not active. This means the PSE has been configured to provide power, but the PD is : Not connected; Has not detected a compliant PD and is not applying power; PSE has turned off power for Reset function; OFF - PSE function switch disabled; RED - Blinking: Error Conditions; Capacitance too High - 1 blink; Resistance too Low or short circuit - 2 blinks; Resistance too high or open circuit - 3 blinks

Disabled (Default)- 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; Enabled- 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.

This green LED is operational only when power is applied. The LED will blink along with transmit/receive data on the fiber port; If a loss of link on the copper port results in a Link Passthrough condition to the fiber port, this LED will blink at a rate of once every 2 seconds until the condition is cleared.

If Auto-Negotiation (802.3u) is enabled, the media converter determines the current cable pinout to use on the copper interface. If Auto-Negotiation (802.3u) is disabled the Media converter will use the RX Energy method on the copper 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 converter's transmitter and the partner devices transmitter are connected to the others receiver. The Media converter's 100Base-TX port is configured as MDI-X with this switch setting.

This green LED is operational only when power is applied. The LED will blink along with transmit/receive data on the 10/100/1000 UTP port; If a loss of link on the copper port results in a Link Passthrough condition to the fiber port, this LED will blink at a rate of once every 2 seconds until the condition is cleared.

This is a technique to perform a power reset on a PD device attached; When enabled ( down ), the media converter will upon loss of link on any fiber port, turn off PSE output power to the PD device for 2 seconds then turn the power back on. The power remains on until any fiber link transitions from up to down again; With Passthrough enabled, a loss of link on the fiber resulting from a loss of link on the copper, a PD Power Reset will occur and the copper link will continue to reflect the state of the fiber link; When PD Power Reset disabled, loss of fiber link has no effect on PSE power to the PD device.
