Chapter 12 PoE

Note:

Only T2600G-28MPS support PoE function.

PoE (Power over Ethernet) technology describes a system to transmit electrical power along

with data to remote devices over standard twisted-pair cable in an Ethernet network. It is

especially useful for supplying power to IP telephones, wireless LAN access points, cameras

and so on.

 Composition

A PoE system usually consists of PSE and PD.

PSE: Power sourcing equipment (PSE) is a device such as a switch that provides power on the

Ethernet cable to the linked device.

PD: A powered device (PD) is a device accepting power from the PSE and thus consumes

energy. PDs fall into two types, standard PDs and nonstandard PDs. Standard PDs refer to the

powered devices that comply with IEEE 802.3af and IEEE 802.3at. Examples include wireless

LAN access points, IP Phones, IP cameras, network hubs, embedded computers etc.

 Advantage

 Cheap cabling: The remote device such as cameras can be powered by PSE in no

need of prolonging its power cord additionally and Ethernet cable is much cheaper

than AC wire or power cord.

 Easy to connect: PoE uses only one Ethernet cable with no need of external power

supply.

 Reliable: A powered device can be either powered by PSE using Ethernet cable or

powered through the provided power adapter. It is very convenient to provide a

backup power supply for the PDs.

 Flexibility: In compliance with IEEE 802.3af and IEEE 802.3at, global organizations can

deploy PoE everywhere without concern for any local variance in AC power standards,

outlets, plugs, or reliability.

 Wide use: It can be applied to wireless LAN access points, IP Phones, IP cameras,

network hubs, embedded computers etc.

T2600G-28MPS is a Power Sourcing Equipment (PSE). All the Auto-Negotiation RJ45 ports on

the switch support Power over Ethernet (PoE) function, which can automatically detect and

supply power for those powered devices (PDs) complying with IEEE 802.3af and IEEE 802.3at.

The maximum power T2600G-28MPS can supply is 384W and the maximum power each PoE

port can supply is 30W.

PoE function can be configured in the two sections, PoE Config and PoE Time-Range.

12.1 PoE Config

All the RJ45 ports on the switch can be configured to supply power for the powered devices

that comply with IEEE 802.3af and IEEE 802.3at. As the power every port or the system can
