Centralized Power Management for Security and Public Service PoE
Applications

To fulll the needs of the high power consumption of PoE network applications, the

GSD/GSW 802.3at PoE+ Switch series features the standard IEEE 802.3at Power
over Ethernet Plus (PoE+) that combines up to 30 watts of power output and data

per port over one Cat5E/6 Ethernet cable. It is designed specically to meet the

demand of the high power consumption of network PDs (powered devices) such as
IR, PTZ, speed dome cameras and even box-type IP cameras with built-in fan and
heater. Compliant with both 802.3at and 802.3af standards, the GSD/GSW 802.3at

PoE+ Switch series allows more exibility in power requirement for a variety of

PDs, making installation costs affordable.

LCD Monitor for Real-time PoE Usage and System Status Display

Easy Installation and Cable Connection

As data transfer and High Power PoE are transmitted over a cable, the GSD/
GSW 802.3at PoE+ Switch series is able to reduce the need of extended cables
and electrical outlets on the wall, ceiling or any unreachable place. It helps to
lower the installation costs and simplify the installation effort. All RJ45 copper
interfaces of the GSD/GSW 802.3at PoE+ Switch series support 10/100Mbps and
10/100/1000Mbps auto-negotiation for optimal speed detection through RJ45
Category 6, 5 or 5e cable. It also supports standard auto-MDI/MDI-X that can
detect the type of connection to any Ethernet device without requiring special
straight-through or crossover cables.

Flexible and Extendable Uplink Solution

The GSD/GSW 802.3at PoE+ Switch series provides 2 extra Gigabit TP or SFP
ports supporting 10/100/1000BASE-T RJ45 copper for surveillance network
devices such as NVR, video streaming server or NAS to facilitate surveillance

management. Or through these Gigabit speed ber SFP slots, the 1000BASE-SX/
LX SFP (Small Form-factor Pluggable) ber transceiver is inserted to be uplinked

to a backbone switch and monitoring center over a long distance. The distance

can be extended from 550m to 2km (multi-mode ber), even going up to above
10/20/30/40/50/60/70/120km (single-mode ber or WDM ber). They are well

suited for applications within the enterprise data centers and distributions.

The device is a power-required device, which means it will not
work till it is powered. If your networks should be active all the
time, please consider using UPS (Uninterrupted Power Supply) for
your device. It will prevent you from network data loss or network
downtime. In some areas, installing a surge suppression device
may also help to protect your 802.3at PoE+ Switch from being
damaged by unregulated surge or current to the Switch or the
power adapter.

3. Hardware Installation

Start up

Please refer to the following for your cabling:

10/100/1000BASE-T

All 10/100/1000BASE-T ports come with Auto-Negotiation capability. They
automatically support 1000BASE-T, 100BASE-TX and 10BASE-T networks. Users
only need to plug a working network device into one of the 10/100/1000BASE-T
ports, and then turn on the 802.3at PoE+ Switch. The port will automatically run
in 10Mbps, 20Mbps, 100Mbps or 200Mbps and 1000Mbps or 2000Mbps after the
negotiation with the connected device.

Cabling

Each 10/100BASE-TX ports and 10/100/1000BASE-T port uses RJ45 sockets -­similar to phone jacks -- for connection of unshielded twisted-pair cable (UTP).
The IEEE 802.3/802.3u/802.3ab Fast/Gigabit Ethernet standard requires Category
5 UTP for 100Mbps 100BASE-TX. 10BASE-T networks can use Cat.3, 4, 5 or
1000BASE-T uses 5/5e/6 UTP (see table below). Maximum distance is 100 meters
(328 feet).

Port Type Cable Type Connector

10BASE-T Cat.3, 4, 5, 2-pair RJ45

100BASE-TX Cat.5, 5e UTP, 4-pair RJ45

1000BASE-T Cat.5/5e/6 UTP, 4-pair RJ45

Any Ethernet devices like hubs/PCs can connect to the 802.3at PoE+ Switch by
using straight-through wires. The whole 10/100/1000Mbps ports are auto-MDI/
MDI-X that can be used on straight-through or crossover cable.

4. Power over Ethernet Overview

What is PoE?

PoE is an abbreviation of Power over Ethernet. The PoE technology means a
system safely transmits both power and data on Ethernet UTP cable. The IEEE
standard for PoE technology requires Category 5 cable or higher for high power
PoE levels, but can operate with Cat3 cable for low power levels. Power is supplied
in common mode over two or more of the differential pairs of wires found in the
Ethernet cables and comes from a power supply within a PoE-enabled network
device such as an Ethernet switch or can be injected into a cable run with a mid­span power supply.

The original IEEE 802.3af-2003 PoE standard provides up to 15.4W of DC power
(minimum 44V DC and 350mA) to each device. Only 12.95W is assured to be
available at the powered device as some power is dissipated in the cable.

The updated IEEE 802.3at-2009 PoE standard, also known as PoE+ or PoE plus,
provides up to 25.5W of power. The 2009 standard prohibits a powered device
from using all four pairs for power.

The 802.3af/802.3at dene two types of source equipment: mid-span and end-

span.

Mid-span

Mid-span device is placed between legacy switch and the powered device. Mid-span
taps the unused wire pairs 4/5 and 7/8 to carry power; the other four are for data
transmit.

End-span

End-span device is directly connected with power device. End-span could also tap
the wire 1/2 and 3/6.

PoE System Architecture

The specication of PoE typically requires two devices: the Powered Source
Equipment (PSE) and the Powered Device (PD). The PSE is either an end-span

or a mid-span, while the PD is a PoE-enabled terminal, such as IP phones, wireless
LAN, etc. Power can be delivered over data pairs or spare pairs of standard Cat5
cabling.

Powered Source Equipment (PSE)

Power sourcing equipment (PSE) is a device such as a switch that provides
(sources) power on the Ethernet cable. The maximum allowed for continuous

output power per cable in IEEE 802.3af is 15.4W. A later specication, IEEE

802.3at, offers 25.50W. When the device is a switch, it is commonly called an

end-span (although IEEE 802.3af refers to it as endpoint). Otherwise, if it is an

27

intermediary device between a non PoE capable switch and a PoE device, it is
called a mid-span. An external PoE injector is a mid-span device.

Powered 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. Depending on the PD design, some, none, or all power can be supplied
from the auxiliary port, with the auxiliary port sometimes acting as backup power
in case of PoE supplied power failure.

How Power is Transferred through Cable

A standard Cat5 Ethernet cable has four twisted pairs, but only two of these are

used for 10BASE-T and 100BASE-TX. The specication allows two options for using

these cables for power, shown in Figure 1 and Figure 2:

The spare pairs are used. Figure 1 shows the pair on pins 4 and 5 connected
together and forming the positive supply, and the pair on pins 7 and 8 connected
and forming the negative supply. (In fact, a late change to the spec allows either
polarity to be used).

The data pairs are used. Since Ethernet pairs are transformers coupled at each
end, it is possible to apply DC power to the center tap of the isolated transformer
without upsetting the data transfer. In this mode of operation, the pair on pins 3
and 6 and the pair on pins 1 and 2 can be of either polarity.

When to install PoE

Consider the following scenarios:

z You’re planning to install the latest VoIP phone system to minimize cabling

building costs when your company moves into a new ofce next month.

z The company staff has been clamoring for a wireless access point in the picnic

area behind the building so they can work on their laptops through lunch, but
the cost of electrical power to the outside is not affordable.

z Management asks for IP Surveillance Cameras and business access systems

throughout the facility, but they would rather avoid another electrician’s
payment.

5. Troubleshooting

This chapter contains information to help you solve issues. If the 802.3at PoE+
Switch is not functioning properly, make sure the 802.3at PoE+ Switch was set up
according to instructions in this manual.

The Link LED is not lit.

Solution:

Check the cable connection and also try to swap one new cable.

1000BASE-T port link LED is lit, but the trafc is irregular.

Solution:

Make sure the attached device is not set to full duplex. Some devices use a
physical or software switch to change duplex modes. Auto-negotiation may not
recognize this type of full-duplex setting.

Why the Switch doesn’t connect to the network

Solution:

Check the LNK/ACT LED on the 802.3at PoE+ Switch. Try another port on the

802.3at PoE+ Switch. Make sure the cable is installed properly. Make sure the

cable is the right type. Turn off the power. After a while, turn on the power again.

Why the GSD-1002VHP/GSW-1820VHP/GSW-2620VHP, connected to PoE
device, cannot be powered on

Solution:

Please check the cable type of the connection from GSD-1002VHP/GSW-1820VHP/
GSW-2620VHP to the other end. The cable should be an 8-wire UTP, Category 5 or
above and EIA568 cable within 100 meters. A cable with only 4-wire, short loop or
over 100 meters will affect the power supply.

Please make sure the device is fully complied with IEEE 802.3af/IEEE 802.3at
standard.

What is the power output of each PoE port?

Solution:

1. Each PoE port supports 53V-54 DC, 600mA and a maximum of 30 watts of
power output. Detect and inject by the standard of IEEE 802.3at.

2. Each PoE port supports 53V-54 DC, 300mA and a maximum of 15.4 watts
of power output. Detect and inject by the standard of IEEE 802.3af.
