Flexible Extension Solution

The two mini-GBIC slots built in the GSD/GSW 802.3at PoE+ Switch series are
compatible with the 1000BASE-SX/LX SFP (Small Form-factor Pluggable)

ber transceiver, uplinked to the backbone switch and monitoring center in long
distance. The distance can be extended from 550 meters (multi-mode ber) to
10/20/30/40/50/60/70/120 kilometers (single-mode ber or WDM ber). They are

well suited for applications within the enterprise data centers and distributions.

Robust Protection

The GSD/GSW 802.3at PoE+ Switch series provides contact discharge of ±6KV DC
and air discharge of ±8KV DC for Ethernet ESD protection. It also supports ±6KV
surge immunity to improve product stability and protects users’ networks from
devastating ESD attacks, making sure the ow of operation does not uctuate.

Easy Installation and Cable Connection

As data and power are transmitted over one cable, the GSD/GSW 802.3at PoE+
Switch series does not need a second cable and electrical outlets on the wall,
ceiling or any unreachable place. Thus, it helps to lower the installation costs and

simplify the installation eort. All the RJ45 copper interfaces of the GSD/GSW

802.3at PoE+ Switch series support 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.

2.3.2 Budget Control

Due to the power allocation strategy of PSE, when the residual power of PoE is
too large, the power distribution of the port can be increased as much as possible
by increasing the power trimming of the PSE, so that the utilization of the PSE
power supply can be improved. There are four levels of budget control named
Unchanged (default), Add 5% PB, Add 10% PB and Add 15% PB.

1. The default PoE budget is 120W/300W in unchanged mode. If
you hope to have a full load of over 120W/300W, please select

Add 5% PB, Add 10% PB and Add 15% PB.

Note

2. In order to make sure the PSE power supply is not overloaded for a long
time, please try to ensure that TP is less than PB.

23

2.3.3 PSE Port Priority

The Priority represents PoE ports priority. There are three levels of power priority

named Low, High and Critical. The priority is used in case the total power

consumption is over the total power budget. In this case the port with the lowest
priority will be turned off, and offer power for the port of higher priority. The
default port priority is “Low”.

2.3.4 PSE Port Enable

Allows user to disable or enable per port PoE function. The default is “Enable”.

24

2.3.5 PD Type

Changing the PoE power-up mode can let non-standard PDs pass the procedures
of PoE power delivery process. This way, the switch can supply power to non­standard PDs. The GSD/GSW 802.3at PoE+ Switch series can set the PoE power­up mode to be in Enhance mode, Standard mode or Legacy mode by the user
interface.

Object Description

Enhance
(default)

Standard Fully conforms to the IEEE 802.3 af/at standard.

Legacy

On the basis of standard mode, change the PD of class 0 to

AT mode; in addition, the current surge limit during power up

increases to the current limit of AT.

The legacy detection is to identify the PD devices that did not
follow the IEEE 802.3af standard and their unique electrical
signatures, in order for the PoE switch to provide the power to
those PD devices.

25

2.3.6 Alive Check

The GSD/GSW 802.3at PoE+ Switch series can be congured to monitor connected
PD’s status in real time via traffic detection. Once there is no traffic at interval

time, the GSD/GSW 802.3at PoE+ Switch series is going to restart PoE port power,
and bring the PD back to work. It will greatly enhance the reliability and reduce
administrator management burden.

This startup time is based on determining when to start to

Trac detection counter.
The switch detects no trac during this time and countdown

for interval time begins and port begins to reboot. The default
interval time is 180 seconds.

PoE Port Disable Timer
This column allows user to set the PoE device rebooting time.

The default power o time is 5 seconds.

26

The PD Alive Check is not a dening standard, so the PoE device on the market
doesn’t report reboots done information to the PoE Switch. So user has to make
sure how long it takes for the PD to nish booting, and then set the time value

related column. The system is going to check the PD again according to the reboot
time. If you cannot make sure the precise booting time, we suggest you set it
longer.

2.3.7 Bandwidth Detection

When the network transmits “the highest data rate”, more than the set value,
over a single port, the switch will set off an alarm to warn the overuse of the
bandwidth. There are four levels of budget control, namely Unlimited (default),
400Mbps, 500Mbps and 600Mbps.

27

2.3.8 Fan Control

Fan control is to achieve the set power with intelligent operation. There are four
levels of budget control, namely Always ON, 20% PB (default), 40% PB and
60% PB.

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

at 10Mbps, 20Mbps, 100Mbps or 200Mbps and 1000Mbps or 2000Mbps after the

negotiation with the connected device.

Cabling

Each 10/100BASE-TX port 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.

It is recommended to use PLANET SFP on the 802.3at PoE+
Switch. If you insert an SFP transceiver that is not supported, the

Note

802.3at PoE+ Switch will not recognize it.

1. Before we connect the 802.3at PoE+ Switch to the other network device, we
have to make sure both sides of the SFP transceivers are with the same media

type, for example, 1000BASE-SX to 1000BASE-SX; 1000BASE-LX to 1000BASE­LX.

2. Check whether the ber-optic cable type matches with the SFP transceiver

requirement.

 To connect to 1000BASE-SX SFP transceiver, please use the multi-mode ber

cable with one side being the male duplex LC connector type.

 To connect to 1000BASE-LX SFP transceiver, please use the single-mode ber

cable with one side being the male duplex LC connector type

 Connect the Fiber Cable

1. Insert the duplex LC connector into the SFP transceiver.

2. Connect the other end of the cable to a device with SFP transceiver installed.

3. Check the LNK/ACT LED of the SFP slot on the front of the 802.3at PoE+

Switch. Ensure that the SFP transceiver is operating correctly.

 Remove the Transceiver Module

1. Make sure there is no network activity anymore.

2. Remove the Fiber-Optic Cable gently.

3. Lift up the lever of the MGB module and turn it to a horizontal position.

4. Pull out the module gently through the lever, as the Figure 3-5 shows.

PoE power output, please make sure the PD’s acceptable DC power
range is from 52-54V DC. Otherwise, it will damage the PD.

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 dierential 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 mid-

span 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nes 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

transmission.

 End-span

End-span device is directly connected with powered 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, oers 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

37

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 oce next month.

z The company sta 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 aordable.

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 tra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 o the power. After a while, turn on the power again.

Why the GSD/GSW Switch, connected to PoE device, cannot be powered on.

Solution:

1. Please check the cable type of the connection from GSD/GSW switch 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 aect the power supply.

2. 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 52-54V 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 52-54V DC, 300mA and a maximum of 15.4 watts

of power output. Detect and inject by the standard of IEEE 802.3af.
