About the Dual Copper Repeater Module
Use this copper repeater module when the:
• design of the network requires a hub-based topology
• segment requires a greater copper distance
• design requires an isolated segment
• number of nodes requires the use of repeaters (refer to Understand Constraints of the
Coax Segment on page 1-17)
The copper repeater module allows multiple 1000m copper segments to be attached to a
repeater adapter (1786-RPA). See pages15-18 for topology examples and segment length
constraints.
The module provides two copper channels and activity status indicators for each channel.
WARNING
If you insert or remove the module while backplane power is
on, an electrical arc can occur. This could cause an explosion
in hazardous location installations.If you insert or remove the
module while backplane power is on, an electrical arc can oc-
cur. This could cause an explosion in hazardous location instal-
lations.
Be sure that power is removed or the area is nonhazardous be-
fore proceeding.
WARNING
If you connect or disconnect the communications cable with
power applied to this module or any device on the network, an
electrical arc can occur. This could cause an explosion in haz-
ardous location installations.
