External Signaling Ports
NOTE: Temperature readings are measured in Kelvin (K), then converted and reported as °C on the LCD panel.
Dry Contact Sensor (Optional)
Two dry contacts on the front panel can be configured as either normally open or normally closed when dry
contacts are installed. When configured as normally open, the dry contact becomes active when the pins are
shorted. When configured as normally closed, the dry contact becomes active when the pins are open. (See the
Settings menu on page 43.)
NOTE: When the dry contact is active, an alarm displays. The alarm is cleared by restoring the hardware connection to
the state before the dry contact became active.
Install and set up the dry contact sensor as instructed in the installation documentation on www.dell.com.
Connect the dry contact sensor to the appropriate port on the rPDU (see Figure 18).
