Installing the Bridging Converter
18
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
5.
❑
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.
