The
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 1-8 lists the PoE
protection temperatures and restoration temperatures
