Link Sentry Configuration

The Link Sentry feature on the MIL-140 is configured through the 4-position DIP switch (refer to Figure 1). Default setting for the DIP switches: All switches are in the “up” position.

Link Sentry allows users to add new management tools to the network. When enabled, it monitors the selected receiver port and, if the Link test signal is not seen, the unit will stop sending a signal through the selected transmit port.

The following table shows which Link Sentry feature is enabled:

Table 1 . Link Sentry Features

Switch	Losing Link on RX of	Stop sending Link on TX of
1 (down)	Fiber port	Fiber port
2 (down)	UTP port	UTP port
3 (down)	UTP port	Fiber port
4 (down)	Fiber port	UTP port

Note: For two MIL-140s used back-to-back and UTP-to-UTP, all DIP switches must be enabled (in the “down” position) on the first MIL-140. On the second MIL-140, enable switches 1 and 4 (in the “down position).

Default setting for Link Sentry: All switches set in the “up” position (disabled). When using the SNMP module to control the Link Sentry feature, leave the switches in the default mode (“up”).
