SRX5400 Firewall Craft Interface Alarm LEDs and Alarm Cutoff/Lamp
Test Button
Two large alarm LEDs are located at the upper right of the craft interface. The circular red LED lights to
indicate a major alarm condition that can result in a system shutdown. The triangular yellow LED lights
to indicate a less severe minor alarm condition that requires monitoring or maintenance. Both LEDs can
be lit simultaneously. A condition that causes an LED to light also activates the corresponding alarm
relay contact on the craft interface.
To deactivate the major and minor alarms, press the button labeled ACO/LT (for "alarm cutoff/lamp
test"), which is located to the right of the alarm LEDs. Deactivating an alarm turns off both LEDs and
deactivates the device attached to the corresponding alarm relay contact on the craft interface.
Table 4 on page 12 describes the alarm LEDs and alarm cutoff button in more detail.
