Connecting To Repeaters - Honeywell EXPERION PKS Installation Manual

Chapter 7 - ControlNet Cable Installation
NOTE
To guard against inadvertent ControlNet outage on a redundant media ControlNet network,
remove power from the ControlNet node (CNI) before removing the ControlNet cables. This will
ensure that the network will not be dropped if one of the redundant ControlNet cables has
already been disconnected or broken. The CNI supports RIUP (Removal/Insertion Under Power)
which enables the removal of the CNI while the ControlNet chassis remains powered.
NOTE
ControlNet devices are never connected directly to the trunk cable, but only through a tap/drop-
cable assembly.
Please review the Removal and Insertion Under Power (RIUP) Function Guidelines in the
Control Hardware Installation Guide before you RIUP any module.
In general, remove and save the tap's dust cap (installed at the loose end of the tap's integral
drop-cable) and connect the loose end of the drop-cable to the proper mating connector on the
ControlNet device.
For details concerning the connection of ControlNet devices to the trunk cable via the tap and
drop-cable assembly, refer to:
