21.2 Hardware Monitor Setup
This section introduces Fan Control for the temperature of the SFP transceiver inserted in the Switch.
When the SFP transceiver temperature exceeds the temperature threshold (see your transceiver
documentation), the Switch automatically turns on the fans with maximum fan speed to cool down the
system.
The fans do not automatically turn off after the SFP transceiver temperature returns below threshold. To
turn off the fans, you have to temporarily disable
SFP Detect or reboot the Switch.
Click SYSTEM > Hardware Monitor Setup to display the screen as shown below.
Note: The SFP Detect feature only functions if at least one of your SFP transceiver(s) support
DDMI (Digital Diagnostic Monitoring Interface). See the transceiver documentation.
