Planning and Designing RIO Cable System

Optional Tap
Enclosure
Considerations
Although not required for overall network integrity, you may consider mounting the
taps in separate enclosures away from the equipment panels. Potential
performance improvements include:
z Avoiding panels, trays, and other enclosures that contain power wiring
z Protecting the network from disruptions caused by accidental trunk cable damage
(drop cable damage usually does not disrupt the entire network)
z Performing wiring for future system expansion within panels to avoid rerouting the
cable later
z Coiling any excess cable within the tap enclosure
Where your overall system design permits it, you may consider locating the
enclosures in the ceiling of the facility to further protect against mechanical damage
to the trunk and taps.
Note: If excess cable is to be coiled within, the recommended enclosure
dimensions are 2 ft (610 mm) long by 2 ft wide by 4 in. (102 mm) deep).
CAUTION
Possible Equipment Failure
Do not mount a tap within a panel or enclosure that contains control
equipment—the trunk and tap become susceptible to potential
problems arising from power source noise, and the cable can be
damaged due to movement by workers or by poor bend radiuses.
Failure to follow this instruction can result in injury or equipment
damage.
