1.2.4 PoE Power Supply

The S9500 series support power over Ethernet (PoE). With this feature, an S9500
switch equipped with an external PoE power supply and PoE-capable LPUs can deliver
–48 VDC to its remotely powered devices (PDs), such as IP phones, wireless LAN
(WLAN) access points (APs) and network cameras, through Ethernet cables.
Currently, among the LPUs of the S9500 series, only GV48 is PoE capable.
The S9500 series can supply power to remote PDs through Ethernet electrical
ports on the LPUs. Each LPU can simultaneously supply power to up to 48 PDs
with the maximum distance of 100 m (328.1 feet).
Each Ethernet port can deliver up to 15.4 W to its PD.
The S9500 series determine whether to deliver power to a newly detected PD
according to the following condition: If the remaining PoE power of the switch is
greater than what is required by a newly detected PD, the switch supplies power to
it. Otherwise, the switch does not supply power to it.
I. PoE power entry module
The PoE-supported S9505/S9508/S9508V/S9512 switch chassis has a PoE power
entry module between the two PSUs. You can connect this PoE power entry module to
an external PoE power supply PSE4500-A.
