My SRX3600 was working fine until i restarted it during a planned shutdown. Now the FPC modules of firewall are shown in present status rather than online and the interfaces won't come up. The firewall show a major alarm of "Fan tray I2C failure" to ">show chassis alarms". The command "> show chassis fan" shows that all the fans are running at normal speed.
Anxiously awaiting your kind help
Could you share the following output:
show chassis environment
show chassis fpc detail
show chassis routing-engine
show chassis temperature-thresholds
show chassis alarms
show chassis fan
Also check if you're hitting the following condition mentioned in KB:
Thank You Karand for your response. The issue was hardware related and was resolved by replacing the fan tray of the device.
