Operation Manual – PoE-PoE ProfileH3C S3100 Series Ethernet Switches Chapter 1 PoE Configuration1-61.2.6 Configuring the PD Compatibility Detection FunctionAfter the PD compatibility detection function is enabled, the switch can detect the PDsthat do not conform to the 802.3af standard and supply power to them.After the PoE feature is enabled, perform the following configuration to enable the PDcompatibility detection function.Table 1-7 Configure the PD compatibility detection functionOperation Command DescriptionEnter system view system-view —Enable the PDcompatibility detectionfunctionpoe legacy enable RequiredDisabled by default.1.2.7 Configuring PoE Over-Temperature Protection on the SwitchIf this function is enabled, the switch disables the PoE feature on all ports when itsinternal temperature exceeds 65°C (149°F) for self-protection, and restores the PoEfeature settings on all its ports when the temperature drops below 60°C (140°F).Table 1-8 Configure PoE over-temperature protection on the switchOperation Command DescriptionEnter system view system-view —Enable PoEover-temperatureprotection on the switchpoetemperature-protectionenableOptionalEnabled by default.Note:z When the internal temperature of the switch decreases from X (X>65°C, or X>149°F)to Y (60°C≤Y<65°C, or 140°F≤Y<149°F), the switch still keeps the PoE functiondisabled on all the ports.z When the internal temperature of the switch increases from X (X<60°C, or X<140°F)to Y (60°C≤65°C, or 140°F ≤149°F), the switch still keeps the PoE functionenabled on all the ports.
