Install the fiber cable, Install Mode

Installation -- Continued

Install Mode

During installation, set converter DIP switch 4 DOWN; leave all other switches in the UP position (default). This disables Transparent Link Pass-Through and Auto-Negotiation, allowing individual copper and fiber links to be established (both copper port LEDs will turn ON with each device-to-device connection) independent of a complete end-to-end connection.

Operation Mode

After installation is complete (all copper and fiber ports connected and linked), set all switches to the UP position (default)).

Fiber Auto-Negotiation

Fiber Auto-Negotiation allows the fiber interface to detect and then advertise the supported features of the remote device; this occurs only when a fiber cable is connected to a device with a negotiating port. The process is as follows:

1.The fiber interface detects the supported features of the remote partner.

2.These abilities are passed to the twisted-pair interface and advertised.

3.Once the twisted-pair interface has a link at the highest common capability, it passes the result to the fiber interface.

4.The fiber interfaces then start advertising these capabilities. At this point, the link between the fiber and the negotiating port is complete.

If the MC-1 is connected via fiber to another MC-1, both media converters must have the Fiber Auto-Negotiation setting disabled (switch 5 UP).

Note: Transparent Link Pass-Through (switch position 4 enabled) cannot be turned OFF (disabled) when Fiber Auto-Negotiation is ON (enabled).

Installation -- continued

Install the fiber cable

1.Locate a 1000Base-SX/LX compliant fiber cable with male, two-stranded TX to RX connectors installed at both ends.

2.Connect the fiber cables to the MC-1 media converter as described:

•Connect the male TX cable connector to the female TX port.

•Connect the male RX cable connector to the female RX port.

3.Connect the fiber cables to the other device (another media converter, hub, etc.) as described:

RX	RX
TX	TX
Device	Device

•Connect the male TX cable connector to the female RX port.

•Connect the male RX cable connector to the female TX port.
