Installation

1.Attach a UTP cable from the network to the RJ-45 port. (Use screened UTP cabling for CISPR 22 class B installation.)

2.Cross-connect the fiber cables: Attach both fiber cables TX to RX and RX to TX from the fiber network cabling to the ST-type connectors on the MIL-C2113.

3.Apply power to the unit:

A.Insert the power adapter’s receptacle into the power plug.

B.Insert the power adapter into a wall outlet.

Diagnostic LEDs and Conditions Indicated

There are five LEDs, including power and:

•TX/ACTIVE: Receiving packets from the 100BASE-TX port.

•FX/ACTIVE: Receiving packets from the 100BASE-FX port.

•TX/LINK: An active connection on the 100BASE-TX port.

•FX/LINK: An active connection on the 100BASE-FX port.

MDI-X/MDI Switch

The MDI-X/MDI switch allows for quick configuration

of the 100BASE-TX port. Cables used when the switch is in the MDI-X position (the “left” position:

•For a hub/repeater, use a swap cable (pins are connected 1 to 3, 2 to 6, 3 to 1, and 6 to 2).

•For a workstation/PC, use a straight-through cable (pins are connected 1 to 1, 2 to 2, 3 to 3, and 6 to 6).

Link Sentry Configuration

The Link Sentry feature on the MIL-C2113 is configured through a 4-position DIP switch (refer to Table 1).

Link Sentry is a troubleshooting feature that allows MiLAN media converters to monitor link states on both fiber and copper ports in the event of a physi- cal link down. If a link down is detected, the converter will automatically notify the end device of the link down by disabling the TX signal of the neighboring port. (see Figure 2.)

(3) Auto Link Down Node B End Node B

Figure 2. Link Sentry Back to Back Configuration

Note: When connecting two MIL-C211X series converters back to back via fiber, Dip Switches 1 & 2 should be in the “up” and 3 & 4 should be in the “down” position.

The following table displays the Link Sentry dip switch settings needed when the MIL-C211X is installed in a single media converter environment (not back to back).

connected 1 to 3, 2 to 6, 3 to 1, and 6 to 2).

Note: The MIL-C211X media converters operate at full duplex. Therefore, when connecting the Copper UTP port, be sure to force the link partner to 100 Full duplex. Failure to force link partner may result in a duplex mismatch when connecting to an auto negotiating device.
