Installing the Bridging Converter

Refer to Table 5 for the cabling specifications for the fiber optic port when

operating in half-duplex mode.

1. The total distance of the fiber optic lengths cannot exceed the limits stated in the table. Each media converter used

inline within a single collision domain reduces the overall segment length by 40 meters (131 feet).

Selecting a Site

Be sure to observe the following guidelines when selecting a site for your

bridging converter.

❑ Select a site that is dust-free and moisture-free.

❑ Select a site that will allow you to easily access the data cables and

power cord.

❑ Use dedicated power circuits or power conditioners to supply reliable

power to the device.

❑ Use the power sources described in “External Power Supply” on page

❑ For the 12-50VDC version, provide regulated DC power only from a

SELV power source per IEC 60950, such as regulated power supplies.

Note

Use only power sources that are UL Listed (QQGQ or EPBU), TUV

Licensed or other Safety Agencies approved, and that are suitable for

country of use.
