SRX5400 Services Gateway 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 6 on page 35 describes the alarm LEDs and alarm cutoff button in more detail.
