Troubleshooting the SRX5800 Services Gateway with the Craft Interface LEDs

The craft interface is the panel on the front of the services gateway located above the card cage that contains LEDs and buttons that allow you to troubleshoot the device.

LEDs on the craft interface include the following:

• Alarm LEDs—One large red circular LED and one large yellow triangular LED, located on the upper right of the craft interface, indicate two levels of alarm conditions. 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. Both LEDs can be lit simultaneously. A condition that causes an alarm LED to light also activates the corresponding alarm relay contact on the craft interface.
• Host subsystem LEDs—Three LEDs, MASTER, ONLINE, and OFFLINE, indicate the status of the host subsystem. A green MASTER LED indicates that the host is functioning as master. The ONLINE LED indicates the host is online. The OFFLINE LED indicates the host is offline. The host subsystem LEDs are located on the left of the craft interface and are labeled RE0 and RE1.
• Power supply LEDs—Two LEDs (PEM) indicate the status of each power supply. Green indicates that the power supply is functioning normally. Red indicates that the power supply is not functioning normally. The power supply LEDs are located in the center of the craft interface, and are labeled 0 through 3.
• IOC and SPC LEDs—Two LEDs, OK and FAIL, indicate the status of each IOC or SPC. Green indicates OK and red indicates a failure. The IOC and SPC LEDs are located along the bottom of the craft interface, and are labeled 0 through 5, 2/6, and 7 through 11.
• SCB LEDs—Two LEDs, OK and FAIL, indicate the status of each SCB. Green indicates OK and red indicates a failure. The SCB LEDs are located in the center of the craft interface along the bottom, and are labeled 0 and 1.
• Fan LEDs—Two LEDs indicate the status of each fan tray. Green indicates OK and red indicates FAIL. The fan LEDs are located on the upper left of the craft interface.
