2.7 Wiring the P-Fail Alarm Contacts
The P-Fail alarm relay is provided to signal critical error conditions that may occur on
the switch. The contacts are energized upon powering up of the switch and remain
energized until a critical error occurs including power failure or Ethernet port
disconnection. Take the wiring illustration below as an example that illustrates the
proper relay connection forming a normally close circuit, and the connection is to be
broken when an error occurs.
