z
Through the fixed 24/48 Ethernet electrical ports, it can supply power to up to 24/48 remote
Ethernet switches with a maximum distance of 100 m (328 feet).
Ethernet switches with a maximum distance of 100 m (328 feet).
z
Each Ethernet electrical port can supply at most a power of 15,400 mW to a PD.
z
When AC power input is adopted for the switch, the maximum total power that can be provided is
300 W. The switch can determine whether to supply power to the next remote PD it detects
depending on its available power.
300 W. The switch can determine whether to supply power to the next remote PD it detects
depending on its available power.
z
When DC power input is adopted for the switch, it is capable of supplying full power to all of the
24/48 ports, that is, 15,400 mW for each port, and the total power is 369.6 W/739.2 W.

z
The PSE processing software on the switch can be upgraded online.
z
The switch provides statistics about power supplying on each port and the whole equipment, which
you can query through the display command.
you can query through the display command.
z
The switch provides two modes (auto and manual) to manage the power feeding to ports in the
case of PSE power overload.
case of PSE power overload.
z
The switch provides over-temperature protection mechanism. Using this mechanism, the switch
disables the PoE feature on all ports when its internal temperature exceeds 65°C (149°F) for
self-protection, and restores the PoE feature on all its ports when the temperature drops below
60°C (140°F).

z
The switch supports the PoE profile feature, that is, different PoE policies can be set for different
user groups. These PoE policies are each saved in the corresponding PoE profile and applied to
ports of the user groups.

When you use the PoE-capable Switch 5500-EI to supply power, the PDs need no external power
supply.

z
If a remote PD has an external power supply, the PoE-capable Switch 5500-EI and the external
power supply will backup each other for the PD.
