Switch Alarm Description
Stratix® 5400 switch The switch lets you connect two alarm inputs from external devices, such as a door or temperature gauge, to the alarm input port on the
front panel of the switch.
An over- or under-temperature alarm or a port not forwarding condition automatically triggers the default output. You can configure the
output alarm relay as either normally energized or de-energized.
Stratix 5410 switch The switch provides the following external alarms:
• Four alarm inputs to sense whether the alarm setting is open or closed. The alarm input is a dry-contact alarm port. You can connect up to
four alarm inputs from devices, such as a door, a temperature gauge, or a fire alarm to the alarm port. An alarm generates a system
message and turns on an alarm status indicator.
• One alarm output that you can configure as a minor or major alarm. Output alarms often control an external alarm, such as a bell or a
light. To connect an external alarm device to the relay, you connect two relay contact wires to complete the electrical circuit.
The front panel alarm port uses an RJ45 connector.

ArmorStratix™ 5700 switch The switch provides the following external alarms:
• One input alarm relay circuit to sense whether the alarm input is open or closed relative to the alarm input reference pin.
• One output alarm relay circuit with one Form C (single-pole, double-throw) relay with one normally open (N.O.) and one normally closed
(N.C.) contact. You can configure the output alarm as either normally energized or normally de-energized.
Stratix 8000/8300 switch The switches provide the following on the front panel:
• Major alarm relay—When closed, the major alarm relay indicates a dual-mode power supply or primary temperature alarm.
• Minor alarm relay—When closed, the minor alarm relay indicates these alarm states:
– Link fault
– Port not forwarding
– Port not operating
– Frame Check Sequence (FCS) bit error rate
