33.1 Overview

The Switch supports DDMI (Digital Diagnostics Monitoring Interface) that allows real-time monitoring of
the SFP transceiver's operating temperature. See
An SFP transceiver in full processing mode might reach the High Temperature (C) Warning Threshold (see
Management > Port Status > DDMI > DDMI Details). This will trigger fans to operate at its MAX FAN Speed
(RPM) to decrease the temperature. A properly functioning fan is an essential component (along with a
sufficiently ventilated, cool operating environment) for the SFP transceiver to stay within the
temperature threshold.

33.1.1 What You Can Do

Use the Hardware Monitor screen to enable the fan to adjust its speed accordingly based on real-time
monitoring of the SFP transceiver's operating temperature.

DESCRIPTION
Select this to allow this Switch to get the operating temperature of the SFP transceiver
connected to its SFP+ slot, and adjust the fan speed accordingly.
Note: It is highly recommended that you enable this setting to prevent the SFP
transceiver from overheating.
