The A3600-24-POE SI, A3600-24-POE EI, A3600-48-POE
SI, and A3600-48-POE EI provides over-temperature
protection mechanism. When the internal temperature exceeds
65°C (149°F), they will stop providing power from all ports.
When the temperature is below 60°C (140°F), they will
continue to provide power from all ports.
Only the recommended PoE power supply can be used for
the A3600-24-POE SI, A3600-24-POE EI, A3600-48-POE SI,

and A3600-48-POE EI. The –48 VDC from the equipment room
cannot be used directly. Otherwise, devices may be damaged.
