The command output displays the SFM slot, status, and temperature of the air flowing past the SPP card and the SPR card. It also displays information about the
SFM power supplies. The chassis management bus (CMB) slave revision level is also displayed.
You can display the environmental status of a particular SFM with the following CLI command: user@host> show chassis environment sfm sfm-lot

Displaying SFM Alarms
Steps To Take To display SFM alarms and error messages, follow these steps:
1.
Display Current SFM Alarms on page 353
2.
Display SFM Error Messages in the System Log File on page 353
3.
Display SFM Error Messages in the Chassis Daemon Log File on page 354
Step 1: Display Current SFM Alarms
Action To display the current SFM alarms, use the following CLI command: user@host> show chassis alarms
Sample Output user@host> show chassis alarms
4 alarms currently active
Alarm time Class Description
2002-05-14 09:23:58 PDT Major SFM Failure
2002-05-14 09:23:55 PDT Major SFM Failure
2002-05-14 09:23:53 PDT Major SFM Failure
2002-05-14 09:20:51 PDT Major No SFM Online, the box is not forwarding
What it Means The command output displays the alarm date, time, severity level, and description.
Step 2: Display SFM Error Messages in the System Log File
Action To display the SFM error messages in the system log file, use the following CLI command: user@host> show log messages
Sample Output user@host> show log messages
Jun 11 20:31:11 hissy-re0 craftd[556]: Major alarm set, No SFM Online, the box is not forwarding
Jun 11 20:31:11 hissy-re0 alarmd[555]: Alarm set: SFM color=RED, class=CHASSIS, reason=No SFM Online, the box is not forwarding
What it Means The messages system log file records the time the failure or event occurred, the severity level, a code, and a message description. You can also use the show log messages | match sfm command to see error messages that are generated when an
SFM fails or is offline. Use this information to diagnose a power supply problem and to let the Juniper Networks Technical Assistance Center (JTAC) know what error messages were generated and the router events that occurred before and after the problem. For more information about system log messages, see the JUNOS System
Log Messages Reference .
