S-1110Dhp-Sc120 Media Converter

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.

Up:The Media Converter will negotiate Ethernet parameters on the fiber connection. This will ensure that the most optimal connection parameters will be in effect. If connecting to another Perle Media Converter, this parameter should be set to Auto. The Media Converter Module will advertise 1000Mbps, Full and Half Duplex, no Pause; Down:The Media Converter Module's fiber will be fixed to 1000Mbps, Full Duplex.

This is a technique to perform a power reset on a PD device(s) 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(s) 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 ( Link Mode enabled and Fiber Auto-Negotiation enabled ) , a loss of link on the fiber resulting from a loss of link on the copper, a PD Power Reset till still occur; When PD Power Reset disabled, loss of fiber link has no effect on PSE power to the PD device(s).

The Fiber Fault Alert switch has meaning when Auto-Negotiation is disabled; Enabled (Default - Up) When the 1000Base-X receiver is off the 1000Base-X transmitter is turned off. Periodically the 1000Base-X receiver will be turned on for a short period to allow the condition to clear if the 1000Base-X link partner is using a similar feature; Disabled (Down)

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

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 combination of FDF,LKF, FDC and PSE indicator LEDs

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.
