To enhance usage in IoT space, the XR8620t comes with dry input sensor. Each input are configurable and manageable in the
iDRAC interface. These are interruptible inputs to iDRAC. Dry means no energy is supplied to the contacts. The dry contact
connection cable with RJ45 connector on one end is custom to each installation and must be provided by the end user.
Figure 10. iDRAC interface for Dry Input sensors
NOTE: Update iDRAC to 6.10.43.05 or later to enable dry contact feature.
NOTE: The RJ45 for dry contact does not support IP function.
The default state of the dry inputs are off/disabled. User will have 7 (one for each dry input) enable/disable (default) control
that must be enabled before logging will occur.
Figure 11. Dry input connection diagram
The 7 dry inputs are interruptible inputs to iDRAC. They have the following characteristics:
●Monitored by iDRAC for state transition and LC event will be logged for each state transition.
Technical specifications 17

●NOT modeled as IPMI sensors but LC event only sensors. The current state of the input is not monitored or displayed
anywhere.
●Event Log - transitions (Open to close or close to Open) will be logged in LC only.
Debounce — A debounce of 100mseconds is provided on all inputs.
