What is PoE?
PoE is “Power over Ethernet”. PoE allows devices that require
power (PD) and supply power (PSE) to be supported over existing
switching infrastructure using at least a Cat5 cabling.
The maximum allowed continuous output power per cable is:
15.40 W for IEEE 802.3af
30 W for IEEE 802.3at

PoE questions
What is a PoE PSE device?
Power sourcing equipment (PSE) is a device such as a switch that provides
("sources") power on the Ethernet cable.
What is a PoE PD device?
A powered device (PD) is a device powered by a PSE and thus consumes
energy. Examples include wireless access points, IP Phones, and IP Cameras.
Many powered devices have an auxiliary power connector for an optional,
external, power supply.

Wireless LAN: Placement of Access Points is
key to delivering an effective wireless network.
PoE supported APs can be placed in strategic
locations – such as ceilings – out of reach of
electrical AC outlets. Deployments can save
on installation costs when PoE capable
switches are leveraged.
Note:
New Wireless APs (Dual Band IEEE802.11AC
wave2) will require PoE+ (802.3at) that
supports up to 25W per port

Voice over IP phones: (VOIP) allow the
delivery of phone signals over a data network
rather than the traditional telephone lines. PoE
addresses one of the primary concerns of
VoIP: reliability and flexibility. PoE enabled IP
phones receive uninterrupted power through
the network, without the need for an AC outlet
for each phone.
Note:
Business conferencing / Colour Display
VoIP Phones / Video Collaboration
based IP Phones, typically require PoE+
(802.3at)

IP Security Cameras and Devices: Security
cameras are traditionally located near
electrical outlets limiting their effectiveness.
Utilising the switching network to mount
cameras and access control devices on
ceilings, hallways, outdoor or reception areas
is significantly less expensive.
Note:
PTZ cameras require 802.3at (PoE+)
Network cameras offer the following
advantages over Analog (or CCTV)
Simple: single cable for power and
video recording. Plus, no more tapes
Standards: use IP and Ethernet to send
traffic. Portable!

Signature detection uses a lower voltage to detect a characteristic signature of IEEE-compatible PDs (a 25kOhm
resistance). Once this signature has been detected, the PSE knows that higher voltages can be safely applied.
Classification follows the signature detection stage, and is an optional process. If a PD displays a classification
signature, it lets the PSE know how much power it requires to operate, as one of three power classes.
If a PD does not display a signature, it is class 0 and must be allocated the maximum 12.95 watts.
POE Plus equipment has a power class of 4. If a regular 802.3af POE source detects this class it will simply
enable power as if it was a class 0 device.
However, an 802.3at PSE will not only recognise the PD as a POE Plus device, it will also repeat the classification
stage, as a signal to the PD that is connected to a power source with full POE Plus power available. POE Plus
PSEs can supply up to 30 watts and available device power is 25.5 watts.
The power negotiation between a PSE and a PD can be implemented at the physical layer or at the data link layer.
After the link is powered at the physical layer, the PSE can use LLDP to repeatedly query the PD to discover the
power needs of the PD. The comm on data link layer allows finer control of power allotment.
Using LLDP is optional for the PSE but mandatory for a PoE+ PD that requires more than 12.95 watts of power.
Detection & Classification
The differences between power delivered by the PSE and
power received by the PD account for power that is due to heat
dissipation.

Data & PoE

1. To date customers have been stuck with choosing between expensive fully managed pass-through
switches or low port count PoE injectors that need to be added to each segment (potentially 3
devices: switch to injector to device)
• GS516TP bridges the gap.
2. PoE injectors typically have a low port count (2 ports). GS516TP means you can deliver a PoE
injector capability AND additional switch ports included in one device AND all the functionality of a
smart switch; Auto VoIP, ACL’s / QoS etc.
• With 22W pass through, you could power 4 IP phones vs 2 devices from an injector
3. PoE injectors warranty?
• We offer LIFETIME on our ProSAFE branded switches.
4. Considering Ethernet’s defined acceptable range is 100 metres, you could use 1 x PoE switch to
power 1 x GS516TP that in turn can then extend another 100 meters to another Powered Device
• Double the distance for power in hard to wire places like old / listed / protected buildings.
5. Per-port priority settings, timers, and power limits can be set to manage power supplied to powered
devices
• Injectors just inject!
6. Adding a power socket to a wall can cost up to twice the price of the GS516TP, depending on country.
• With a new wall socket, that’s electricians, walls being ripped, cables laid and plastering and painting required. Very expensive.
• With a Passthrough capable PoE switch, just plug and play.
• Once new cabling is laid, it’s fixed in place. GS516TP is flexible – it can be moved to new locations.
