Installing DNP3 I/O Modules in a Rack
Rack Spacing
When mounting multiple DNP3 I/O modules in a rack, or when mounting DNP3 I/O modules in a rack
with other equipment , verify that there is at least one rack unit (RU) of space above and below the
DNP03 I/O module to allow for cooling air flow and cable routing (1 RU = 1.75 inches or 44.5 mm).
