5.1   Monitoring 
LED 
When the switch is running, you can monitor the switch and module status by observing the LED.   
  If  the Status  LED is  red, it  indicates that  the system  is not  functioning  properly.  Log in to  the software 
management system to troubleshoot the fault. 
  If the Status LED is yellow, it means the system temperature exceeds the threshold, affecting the system 
operation performance. However, the system can keep running. Log in to the software management system 
to troubleshoot the fault. 
  If the  FAN LED  is red, it indicates  that a fan module is not  functioning properly.  Log in  to the software 
management system to troubleshoot the fault. 
  If the Status LED of the device or the expansion module is red or flashing, it indicates the switch is faulty. You 
are advised to identify the fault cause, and power off the switch when necessary. 
  If the RWR1/PWR2 LED of the device is red, it means that the power supply is faulty. You are advised to 
replace the power supply module. 
CLI Commands 
The switch allows you to monitor various system statuses by executing the appropriate CLI commands, including: 
  Working status of the switch 
  Configuration information and status of port 
  Working status of fan and power supply 
  Temperature status 
 
Note 
  For the monitoring commands, refer to RG-S6150-X Series Switches RGOS Configuration Guide.
