MONITORING AND MAINTENANCE

Monitoring
Indicator
When the QSW-6900-56LF is running, users can monitor the status of host and each module by
inspecting corresponding indicators.
❖
When the Status indicator is red, it means the system has a fault, in which case you can
determine and eliminate the fault by viewing with the management software.
❖
When the Status indicator is yellow, it means the system temperature exceeds the alarm
temperature, affecting the system operation performance. However, the system can
continue running. In this case, you can determine and eliminate the fault by viewing with the
management software.
❖
When the indicator of the fan module is red, it means that a fan tray is faulty and the system
can continue running, in which case you can determine and eliminate the fault by viewing
with the management software.
❖
When the indicator of the host or the extension module is red or flashing, it indicates a
failure, in which case you need to find out the cause, and turn off the power when necessary.
❖
When the RWR1/PWR2 indicator of the device is red, it means that the power supply is
faulty, in which case you should replace it promptly.
