The PowerEdgeXR8720tsystem supports 1 x RJ45 for dry contact on front of
the system.
To enhance usage in IoT space, the XR8720t 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.

sensors
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.

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.
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 100ms is provided on all
inputs.
