Craft Interface Alarm Leds; Craft Interface Sib Leds - Juniper PTX5000 Hardware Manual

Craft Interface Alarm LEDs

Two large alarm LEDs are located on the craft interface. Both LEDs can be lit simultaneously.
• The circular red LED lights to indicate a critical condition that can result in a system shutdown.
• The triangular yellow LED lights to indicate a less severe condition that requires monitoring or
maintenance.
The LCD display on the craft interface reports the cause of the alarm. A condition that causes an alarm
LED to light also activates the corresponding alarm relay contact on the craft interface.
Table 3 on page 24 describes the alarm LEDs.
