    It is not recommended to insert an I/O Module into the multi-slot I/O card cage of the IRRInet-XL RTU while the RTU is powered on. To replace an I/O Module first power off the RTU then remove or insert the new I/O Module. However, powering off the RTU causes all the data inside the CPU Module RAM to be erased.
