1.2.4 PoE Power Supply

The S9500 series support power over Ethernet (PoE). With this feature, a S9500 series
switch equipped with external power supply and PoE-capable cards can deliver 48
VDC to remotely powered devices (PDs, such as IP Phones, WLAN APs and Network
Cameras) through twisted pairs.

The S9500 series can supply power to remote PDs through the Ethernet electrical
ports on the LPUs. Each LPU can simultaneously supply power to up to 48 PDs at
a distance of up to 100 m (328.1 feet) away.

Each Ethernet port can deliver up to 15.4 W to its PD.

Totally, an S9500 series switch can deliver up to 4500 W (220 V)/2250 W (110 V)
power to its PDs. It determines whether to deliver power to the newly detected PD
depending on the power it currently supplied.

I. PoE entry area

On the S9500 series, the PoE entry area is between the two power supply modules.
The PoE entry module is connected with the wiring screw post of the power frame when
supported.

II. External PoE power frame

The following two types of PoE external power supplies are available for the S9500
series:

PSE4500-A: adopted by S9505/S9508/S9512 switches

PSE2500-A1: adopted by S9502 switches

Currently the S9500 series support the PoE power system with three AC inputs and
one DC output. The PoE power frame with three AC inputs is shown Figure 1-9:
