Troubleshooting The Srx5400 Services Gateway With The Component Leds - Juniper SRX5400 Hardware Manual

Alarm LEDs—One large major alarm circular LED and one large minor alarm triangular LED, located on
the upper right of the craft interface, indicate two levels of alarm conditions. The circular major alarm
LED lights to indicate a critical condition that can result in a system shutdown. The triangular minor
alarm 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 craft interface, and are labeled 0 through 3.
Card OK/Fail LEDs—Two LEDs, OK and FAIL, indicate the status of the card in each slot in the card
cage. Green indicates OK and red indicates a failure. The card OK/Fail LEDs are located along the bottom
of the craft interface, and are labeled 0 through 5.
SCB LEDs—Two LEDs, OK and FAIL, indicate the status of the 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 the fan. Green indicates OK and red indicates FAIL. The fan
LEDs are located on the upper left of the craft interface.

Troubleshooting the SRX5400 Services Gateway with the Component LEDs

The following LEDs are located on various services gateway components and display the status of those
components:
Card LED—One LED labeled OK/FAIL on each card in the card cage indicates the card's status.
MIC LED—One LED labeled OK/FAIL on the faceplate of each MIC installed in an MPC indicates the
MIC's status.
SCB LEDs—Three LEDs, labeled FABRIC ACTIVE, FABRIC ONLY, and OK/FAIL , on each SCB faceplate
indicate the status of the SCB. If no LEDs are lit, the master Routing Engine might still be booting, or the
SCB is not receiving power.
Routing Engine LEDs—Four LEDs, labeled MASTER, HDD, ONLINE, and FAIL on the Routing Engine
faceplate indicate the status of the Routing Engine and hard disk drive.
Power supply LEDs—Three or four LEDs on each power supply faceplate indicate the status of that
power supply.
