Installation Manual
H3C S5100-SI/EI Series Ethernet Switches
Chapter 1 Product Overview
1-34
The S5100-8P-PWR-EI, S5100-16P-PWR-EI, S5100-26C-PWR-EI, and
S5100-50C-PWR-EI Ethernet switches provide over-temperature protection. With this
mechanism, the switch disables the PoE feature on all its ports for self-protection when
its internal temperature exceeds the PoE protection temperature, and restores the PoE
feature on all its ports when its internal temperature drops below the PoE restoration
temperature. Table 1-14 lists the PoE protection temperatures and restoration
temperatures
