1.5 S5750P POE Function
POE, the abbreviation for Power over Ethernet, is the latest specification (802.3af) that
transmits both data and electric power on the existing standard Ethernet cable and supports
compatibility with the existing Ethernet systems and users.
One complete POE system consists of the Power Sourcing Equipment (PSE) and Power
Device (PD). The PSE is the equipment that powers the Ethernet client and also manages
the entire POE process. The PD is the PSE load that receives the power, that is, the client
device of the POE system, for example, IP phone, network safety camera, AP and PDA or
mobile phone charger.
Our RG-S5750P-24GT/12SFP and RG-S5750P-48GT/4SFP switches support the 802.3af
POE standard, full-power POE at 15.4 W for the 24/48 RJ45 ports on the front panel. Also it
provides the advanced management and POE status indication. The S5750P 1000M electric
port can automatically recognize the PD device plugged and powers the PD device by
default. To allow users to easily observe the POE status of the switch, the 24 electrical ports
of the S5750P all have the POE indication function. When you press the MOD switching
button and the MOD-LED is orange, the port LED of the switch shows the POE status. For
the meanings of each port LED in this case, see Table 1-3 . When you press the MOD button
