4.6 VLANs
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic
so only members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN from a switch is
logically equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network
devices are still plug into the same switch physically.
The Gigabit Ethernet Switch supports 802.1Q (tagged-based) and Port-based VLAN setting in web management page. In
the default configuration, VLAN support is “802.1Q”.
Port-based VLAN
Port-based VLAN limit traffic that flows into and out of switch ports. Thus, all devices connected to a port are members of
the VLAN(s) the port belongs to, whether there is a single computer directly connected to a switch, or an entire
department.
On port-based VLAN.NIC do not need to be able to identify 802.1Q tags in packet headers. NIC send and receive normal
Ethernet packets. If the packet's destination lies on the same segment, communications take place using normal Ethernet
protocols. Even though this is always the case, when the destination for a packet lies on another switch port, VLAN
considerations come into play to decide if the packet is dropped by the Switch or delivered.
IEEE 802.1Q VLANs
IEEE 802.1Q (tagged) VLAN are implemented on the Switch. 802.1Q VLAN require tagging, which enables them to span
the entire network (assuming all switches on the network are IEEE 802.1Q-compliant).
VLAN allow a network to be segmented in order to reduce the size of broadcast domains. All packets entering a VLAN will
only be forwarded to the stations (over IEEE 802.1Q enabled switches) that are members of that VLAN, and this includes
broadcast, multicast and unicast packets from unknown sources.
VLAN can also provide a level of security to your network. IEEE 802.1Q VLAN will only deliver packets between stations
that are members of the VLAN. Any port can be configured as either tagging or untagging. The untagging feature of IEEE
802.1Q VLAN allows VLAN to work with legacy switches that don't recognize VLAN tags in packet headers. The tagging
feature allows VLAN to span multiple 802.1Q-compliant switches through a single physical connection and allows
Spanning Tree to be enabled on all ports and work normally.

4.7 Rapid Spanning Tree
Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges. STP also provides one path
between end stations on a network, eliminating loops.
Rapid Spanning Tree Protocol (RSTP) - While Classic Spanning Tree guarantees preventing L2 forwarding loops in a
general network topology, convergence can take up to 30-60 seconds. The convergence time is considered too long for
many applications. When network topology allows, faster convergence may be possible. The Rapid Spanning Tree
Protocol (RSTP) detects and uses of network topologies that provide faster convergence of the spanning tree, without
creating forwarding loops.
The devices support the following Spanning Tree protocols:
‧ Compatiable -- Spanning Tree Protocol (STP):Provides a single path between end stations, avoiding and
eliminating loops.
‧ Normal -- Rapid Spanning Tree Protocol (RSTP) : Detects and uses of network topologies that provide
faster spanning tree convergence, without creating forwarding loops.
#Notice:
The Gigabit Ethernet Switch implement the Rapid Spanning Protocol as the default spanning tree
protocol. While select “Compatibles” mode, the system use the RSTP (802.1w) to compatible and
co work with another STP (802.1d)’s BPDU control packets.
This page is to enable/disable the Spanning Tree protocol. The switch support IEEE 802.1d Spanning Tree (STP), IEEE
802.1w Rapid Spanning Tree (RSTP). The screen in Figure 4-7-1 appears.

Indicate port 1 to port 8.
• Edge
Indicates whether the port is enabled as an edge port.
Edge port cannot create loops, but it loses edge port status if a topology change
creates a potential for a loop. An edge port normally should not receive BPDU
packets. If a BPDU packet is received it automatically loses edge port status.
• Path Cost
The port contribution to the root path cost. The path cost is adjusted to a higher or
lower value, and is used to forward traffic when a path being rerouted.
Value Rage : 1-20000000.
Default Path Cost -- The default path cost of the port is automatically set by the
port speed and the default path cost method. The default values for path costs
are:
- Ethernet – 2000000.
- Fast Ethernet - 200000.
- Gigabit Ethernet - 20000.
• Port Priority

4.8 Link Aggregation
Port Aggregation optimizes port usage by linking a group of ports together to form a single Link Aggregated Groups
(LAGs). Port Aggregation multiplies the bandwidth between the devices, increases port flexibility, and provides link
redundancy.
Each LAG is composed of ports of the same speed, set to full-duplex operations. Ports in a LAG, can be of different media
types (UTP/Fiber, or different fiber types), provided they operate at the same speed.
Aggregated Links can be assigned manually (Port Trunk) or automatically by enabling Link Aggregation Control Protocol
(LACP) on the relevant links.
Aggregated Links are treated by the system as a single logical port. Specifically, the Aggregated Link has similar port
attributes to a non-aggregated port, including auto-negotiation, speed, Duplex setting, etc.

• Ports can only be assigned to one link aggregation.
• The ports at both ends of a connection must be configured as link aggregation ports.
• None of the ports in a link aggregation can be configured as a mirror source port or a mirror
target port.
• All of the ports in a link aggregation have to be treated as a whole when moved from/to, added
or deleted from a VLAN.
• The Spanning Tree Protocol will treat all the ports in a link aggregation as a whole.
• Disconnect all link aggregation port cables or disable the link aggregation ports before removing
a port link aggregation to avoid creating a data loop.

4.9 IGMP Snooping
The Internet Group Management Protocol (IGMP) lets host and routers share information about multicast groups
memberships. IGMP snooping is a switch feature that monitors the exchange of IGMP messages and copies them to the
CPU for feature processing. The overall purpose of IGMP Snooping is to limit the forwarding of multicast frames to only
ports that are a member of the multicast group.
4.9.1 IGMP Snooping Configuration
The IGMP Configuration page let the administrator to configure the parameters for IGMP Snooping, which is used to build
forwarding lists for multicast traffic. The screen in Figure 4-9-1 appears.
Figure 4-9-1 IGMP Snooping Configuration and Status
The page includes the following fields:
Object
Description
• IGMP Enable
Enables or disables IGMP global function on the device.
Disabled is the default value.
• Router Ports
The Router Ports check box fields for attaching ports to a device that is attached to a
neighboring Multicast router/switch. Once IGMP Snooping is enabled, Multicast
packets are forwarded to the appropriate port .
• Unregistered IPMC
Flooding Enable
The function is to set “Enable” or “Disable” to allow the unregistered IP Multicast
Group streams to flood to all ports of this switch. The unregistered IP Multicast means
that the received Multicast Group address not listed in the Multicast Group Table of
the switch.
Enabled is the default value. The switch forwards all the multicast steams to all the
host or linked switch.
• VLAN ID
Identifies a VLAN and contains information about the Multicast group configuration.
Add a new VLAN group and the Table will add the VLAN entry automatically.
• IGMP Snooping
Enabled
Enables or disables IGMP snooping on the VLAN. Ports be assign to the VLAN will be
applied to filter the Multicast stream.
Enabled is the default value.
• IGMP Querying
Enabled
Enables or disables IGMP Query mode on the VLAN. The Query mode is used to
periodically check the multicast group for members that are no longer active. In the
case where there is more than one multicast router on a sub network, one router is
User’s Manual of GSD-802S / GSD-802PS
elected as the ‘queried’. This router then keeps track of the membership of the
multicast groups that have active members. The information received from IGMP is
then used to determine if multicast packets should be forwarded to a given sub
network or not. The router can check, using IGMP, to see if there is at least one
member of a multicast group on a given subnet work. If there are no members on a
sub network, packets will not be forwarded to that sub network.
Enabled is the default value.
Add a new VLAN group, the VLAN ID will be added to the table automatically with both “IGMP
Snooping Enabled” and “IGMP Querying Enabled”.

4.10 Quality of Service
Quality of Service (QoS) is an advanced traffic prioritization feature that allows you to establish control over network traffic.
QoS enables you to assign various grades of network service to different types of traffic, such as multi-media, video,
protocol-specific, time critical, and file-backup traffic.
QoS reduces bandwidth limitations, delay, loss, and jitter. It also provides increased reliability for delivery of your data and
allows you to prioritize certain applications across your network. You can define exactly how you want the switch to treat
selected applications and types of traffic.
You can use QoS on your system to:
• Classifying traffic based on packet attributes.
• Assigning priorities to traffic (for example, to set higher priorities to time-critical or business-critical applications).
• Applying security policy through traffic filtering.
• Provide predictable throughput for multimedia applications such as video conferencing or voice over IP by
minimizing delay and jitter.
• Improve performance for specific types of traffic and preserve performance as the amount of traffic grows.
• Reduce the need to constantly add bandwidth to the network.
• Manage network congestion.
The QoS Configuration page contains fields for enabling or disabling QoS. In addition, the 802.1p mode or DSCP mode
can be selected. Both the two mode rely on predefined fields within the packet to determine the output queue.
„
Queue Mode - This indicates that traffic scheduling for the selected queue is based strictly or WRR ( Weight
Round Robin ) on the queue priority.
„
QoS Disabled - Disables managing network traffic using Quality of Service.
„
802.1p Mode –The output queue assignment is determined by the IEEE802.1p VLAN priority tag.
„
DSCP Mode - The output queue assignment is determined by the DSCP field.
The current version of GSD-800S/GSD-802S/GSD-802PS support QoS Strict mode only. The strict
mode is to specifies if traffic scheduling is based strictly on the queue priority.
The QoS Configuration page in Figure 4-10-1 appears.

4.11 802.1X Management
The PLANET Gigabit Ethernet Switch supports IEEE 802.1X Port-base network access control and RADIUS server
authentication to enhance the host link more security. An 802.1X Infrastructure is composed of three major components:
Authenticator, Authentication server, and Supplicant.
Authentication server – (RADIUS Server): An entity that provides an authentication service to an authenticator. This
service determines, from the credentials provided by the supplicant, whether the supplicant is authorized to access the
services provided by the authenticator.
Authenticator-(GSD-802PS): An entity at one end of a point-to-point LAN segment that facilitates authentication of the
entity attached to the other end of that link.
Supplicant-(A Host Client): An entity at one end of a point-to-point LAN segment that is being authenticated by an
authenticator attached to the other end of that link.
The instructions are divided into three parts:
The above graph shows the network topology of the solution we are going to introduce. As illustrated, a group of clients is
trying to build a network with Switch in order to have access to both Internet and Intranet. With 802.1X authentication,
each of these clients would have to be authenticated by RADIUS server. If the client is authorized, Switch would be
notified to open up a communication port to be used for the client. There are 2 Extensive Authentication Protocol (EAP)
methods supported: (1) MD5 and (2) TLS.
MD5 authentication is simply a validation of existing user account and password that is stored in a database of RADIUS
server. Therefore, clients will be prompted for account/password validation to build the link. TLS authentication is a more
complicated authentication, which is using certificate that is issued by RADIUS server for authentication. TLS
authentication is a more secure authentication, since not only RADIUS server authenticates the client, but also the client
can validate RADIUS server by the certificate that it issues. The TLS authentication request from clients and reply by
Radius Server and Switch can be briefed as follows:
1.
The client sends an EAP start message to Web-Smart Switch.
2.
Web-Smart Switch replies with an EAP Request ID message.
3.
The client sends its Network Access Identifier (NAI) – its user name – to Web-Smart Switch in an EAP Respond
message.
4.
Web-Smart Switch forwards the NAI to the RADIUS server with a RADIUS Access Request message.
5.
The RADIUS server responds to the client with its digital certificate.
6.
The client validates the digital certificate, and replies its own digital certificate to the RADIUS server.
7.
The RADIUS server validates client’s digital certificate.
User’s Manual of GSD-802S / GSD-802PS
8.
The client and RADIUS server derive encryption keys.
9.
The RADIUS server sends Web-Smart Switch a RADIUS ACCEPT message.
10. Web-Smart Switch sends the client an EAP Success message along with the broadcast key and key length.
This section is to control the access of the switch, includes the user access and management control. The 802.1X
Management page contains links to the following topics:
• 802.1X Configuration
• 802.1X Parameter

disruption of the link or of any data transfer.
„
If the link is established in 100BASE-TX or 10BASE-T, the Cable Diagnostics cause the link to drop while the
diagnostics are running.
After the diagnostics are finished, the link is reestablished. And the following functions are available.
• Coupling between cable pairs.
• Cable pair termination
• Cable Length
Anomalous coupling between cable pairs can be caused by shorted wires, improper termination, or high crosstalk
resulting from an incorrect wire map. These conditions can all prevent the PLANET switch from establishing a link. The
screen in Figure 4-14-9 appears.

D (Pin 7,8)
• Length[m]
When properly terminated, Cable Diagnostics reports the approximate cable
length in meters of each of the four cable pair A, B, C, and D.
• Status
The cable test results. Possible values are:
• Proper - The cable passed the test.
• Open - The cable is connected on only one side or there is no cable connected
to the port
• Short - A short has occurred in the cable. With 10/100BASE link, the status of
Pair C and Pair D will be “Short”.
• Abnormal termination – An improper termination be detected. Proper
termination of Cat5 cable requires a 100Ω differential impedance between
the positive and negative cable terminals. IEEE Std 802.3 allows for a
termination of as large as 115Ω or as small as 85Ω. If the termination
falls out of this range, it is reported as falls an anomalous termination.
Be sure to running the Cable diagnostics with standard Cat 5e or Cat 6 UTP cable. With some of the
UTP cables that not match the standard of Cat 5e, it might cause the 10/100Base link down after the
cable diagnostics.

5. SWITCH OPERATION
5.1 Address Table
The Switch is implemented with an address table. This address table composed of many entries. Each entry is used to
store the address information of some node in network, including MAC address, port no, etc. This information comes from
the learning process of Ethernet Switch.
5.2 Learning
When one packet comes in from any port, the Switch will record the source address, port no. And the other related
information in address table. This information will be used to decide either forwarding or filtering for future packets.
5.3 Forwarding & Filtering
When one packet comes from some port of the Ethernet Switching, it will also check the destination address besides the
source address learning. The Ethernet Switching will lookup the address-table for the destination address. If not found,
this packet will be forwarded to all the other ports except the port, which this packet comes in. And these ports will transmit
this packet to the network it connected. If found, and the destination address is located at different port from this packet
comes in, the Ethernet Switching will forward this packet to the port where this destination address is located according to
the information from address table. But, if the destination address is located at the same port with this packet comes in,
then this packet will be filtered. There by increasing the network throughput and availability.
5.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A Store-and-Forward Ethernet Switching stores the
incoming frame in an internal buffer, do the complete error checking before transmission. Therefore, no error packets
occurrence, it is the best choice when a network needs efficiency and stability.
The Ethernet Switch scans the destination address from the packet-header, searches the routing table provided for the
incoming port and forwards the packet, only if required. The fast forwarding makes the switch attractive for connecting
servers directly to the network, thereby increasing throughput and availability. However, the switch is most commonly
used to segment existing hubs, which nearly always improves overall performance. An Ethernet Switching can be easily
configured in any Ethernet network environment to significantly boost bandwidth using conventional cabling and adapters.
Due to the learning function of the Ethernet switching, the source address and corresponding port number of each
incoming and outgoing packet are stored in a routing table. This information is subsequently used to filter packets whose
destination address is on the same segment as the source address. This confines network traffic to its respective domain,
reducing the overall load on the network.
The Switch performs "Store and forward" therefore, no error packets occur. More reliably, it reduces the re-transmission
rate. No packet loss will occur.
User’s Manual of GSD-802S / GSD-802PS
5.5 Auto-Negotiation
The STP ports on the Switch have built-in “Auto-negotiation”. This technology automatically sets the best possible
bandwidth when a connection is established with another network device (usually at Power On or Reset). This is done by
detect the modes and speeds at the second of both device is connected and capable of, both 10Base-T and 100Base-TX
devices can connect with the port in either Half- or Full-Duplex mode. 1000Base-T can be only connected in Full-duplex
mode.
5.6 IGMP Snooping
Theory
Computers and network devices that want to receive multicast transmissions need to inform nearby routers that they will
become members of a multicast group. The Internet Group Management Protocol (IGMP) is used to communicate this
information. IGMP is also used to periodically check the multicast group for members that are no longer active. In the case
where there is more than one multicast router on a sub network, one router is elected as the ‘queried’. This router then
keeps track of the membership of the multicast groups that have active members. The information received from IGMP is
then used to determine if multicast packets should be forwarded to a given sub network or not. The router can check, using
IGMP, to see if there is at least one member of a multicast group on a given subnet work. If there are no members on a sub
network, packets will not be forwarded to that sub network.
IGMP Versions 1 and 2
Multicast groups allow members to join or leave at any time. IGMP provides the method for members and multicast routers
to communicate when joining or leaving a multicast group.
IGMP version 1 is defined in RFC 1112. It has a fixed packet size and no optional data.
The format of an IGMP packet is shown below:
IGMP Message Format

The IGMP Type codes are shown below:

0x11 Specific Group Membership Query (if Group Address is Present)
0x16 Membership Report (version 2)
0x17 Leave a Group (version 2)
0x12 Membership Report (version 1)
IGMP packets enable multicast routers to keep track of the membership of multicast groups, on their respective sub
networks. The following outlines what is communicated between a multicast router and a multicast group member using
IGMP.
A host sends an IGMP “report” to join a group
User’s Manual of GSD-802S / GSD-802PS
A host will never send a report when it wants to leave a group (for version 1).
A host will send a “leave” report when it wants to leave a group (for version 2).
Multicast routers send IGMP queries (to the all-hosts group address: 224.0.0.1) periodically to see whether any group
members exist on their sub networks. If there is no response from a particular group, the router assumes that there are no
group members on the network.
The Time-to-Live (TTL) field of query messages is set to 1 so that the queries will not be forwarded to other sub networks.
IGMP version 2 introduces some enhancements such as a method to elect a multicast queried for each LAN, an explicit
leave message, and query messages that are specific to a given group.
The states a computer will go through to join or to leave a multicast group are shown below:

6. POWER OVER ETHERNET OVERVIEW
What is PoE?
Based on the global standard IEEE 802.3af, PoE is a technology for wired Ethernet, the most widely installed local area
network technology adopted today. PoE allows the electrical power necessary for the operation of each end-device to be
carried by data cables rather than by separate power cords. New network applications, such as IP Cameras, VoIP
Phones, and Wireless Networking, can help enterprises improve productivity. It minimizes wires that must be used to
install the network for offering lower cost, and less power failures.
IEEE802.3af also called Data Terminal equipment (DTE) power via Media dependent interface (MDI) is an international
standard to define the transmission for power over Ethernet. The 802.3af is delivering 48V power over RJ-45 wiring.
Besides 802.3af also define 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 is tap the unused wire pairs 4/5
and 7/8 to carry power, the other four is for data transmit.
„
End-Span
End-Span device is direct connecting with power device. End-Span could also tap the wire 1/2 and 3/6.
PoE System Architecture
The specification 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 CAT-5 cabling.
How Power is Transferred Through the Cable
A standard CAT5 Ethernet cable has four twisted pairs, but only two of these are used for 10BASE-T and 100BASE-T. The
specification allows two options for using these cables for power, shown in Figure 2 and Figure 3:
The spare pairs are used. Figure 2 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).
Figure 1 - Power Supplied over the Spare Pins
User’s Manual of GSD-802S / GSD-802PS
The data pairs are used. Since Ethernet pairs are transformer coupled at each end, it is possible to apply DC power to the
center tap of the isolation 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.
Figure 2 - Power Supplied over the Data Pins
When to install PoE?
Consider the following scenarios:
• • You're planning to install the latest VoIP Phone system to minimize cabling building costs when your company moves
into new offices next month.
• • 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.
• • Management asks for IP Surveillance Cameras and business access systems throughout the facility, but they would
rather avoid another electrician's payment.

The PoE Provision Process
While adding PoE support to networked devices is relatively painless, it should be realized that power cannot simply be
transferred over existing CAT-5 cables. Without proper preparation, doing so may result in damage to devices that are not
designed to support provision of power over their network interfaces.
The PSE is the manager of the PoE process. In the beginning, only small voltage level is induced on the port's output, till
a valid PD is detected during the Detection period. The PSE may choose to perform classification, to estimate the amount
of power to be consumed by this PD. After a time-controlled start-up, the PSE begins supplying the 48 VDC level to the
PD, till it is physically or electrically disconnected. Upon disconnection, voltage and power shut down.
Since the PSE is responsible for the PoE process timing, it is the one generating the probing signals prior to operating the
PD and monitoring the various scenarios that may occur during operation.
All probing is done using voltage induction and current measurement in return.

Line Detection
Before power is applied, safety dictates that it must first be ensured that a valid PD is connected to the PSE's output. This
process is referred to as "line detection", and involves the PSE seeking a specific, 25 KΩ signature resistor. Detection of
this signature indicates that a valid PD is connected, and that provision of power to the device may commence.
The signature resistor lies in the PD's PoE front-end, isolated from the rest of the the PD's circuitries till detection is
certified.
Classification
Once a PD is detected, the PSE may optionally perform classification, to determine the maximal power a PD is to
consume. The PSE induces 15.5-20.5 VDC, limited to 100 mA, for a period of 10 to 75 ms responded by a certain current
consumption by the PD, indicating its power class.
The PD is assigned to one of 5 classes: 0 (default class) indicates that full 15.4 watts should be provided, 1-3 indicate
various required power levels and 4 is reserved for future use. PDs that do not support classification are assigned to class
0. Special care must be employed in the definition of class thresholds, as classification may be affected by cable losses.
Classifying a PD according to its power consumption may assist a PoE system in optimizing its power distribution. Such a
system typically suffers from lack of power resources, so that efficient power management based on classification results
may reduce total system costs.
User’s Manual of GSD-802S / GSD-802PS
Start-up
Once line detection and optional classification stages are completed, the PSE must switch from low voltage to its full
voltage capacity (44-57 Volts) over a minimal amount of time (above 15 microseconds).
A gradual startup is required, as a sudden rise in voltage (reaching high frequencies) would introduce noise on the data
lines.
Once provision of power is initiated, it is common for inrush current to be experienced at the PSE port, due to the PD’s
input capacitance. A PD must be designed to cease inrush current consumption (of over 350 mA) within 50 ms of power
provision startup.
Operation
During normal operation, the PSE provides 44-57 VDC, able to support a minimum of 15.4 watts power.
Power Overloads
The IEEE 802.3af standard defines handling of overload conditions. In the event of an overload (a PD drawing a higher
power level than the allowed 12.95 Watts), or an outright short circuit caused by a failure in cabling or in the PD, the PSE
must shut down power within 50 to 75 milliseconds, while limiting current drain during this period to protect the cabling
infrastructure. Immediate voltage drop is avoided to prevent shutdown due to random fluctuations.
Power Disconnection Scenarios
The IEEE 802.3af standard requires that devices powered over Ethernet be disconnected safely (i.e. power needs be shut
down within a short period of time following disconnection of a PD from an active port).
When a PD is disconnected, there is a danger that it will be replaced by a non-PoE-ready device while power is still on.
Imagine disconnecting a powered IP phone utilizing 48 VDC, then inadvertently plugging the powered Ethernet cable into
a non-PoE notebook computer. What’s sure to follow is not a pretty picture.
The standard defines two means of disconnection, DC Disconnect and AC Disconnect, both of which provide the same
functionality - the PSE shutdowns power to a disconnected port within 300 to 400ms. The upper boundary is a physical
human limit for disconnecting one PD and reconnecting another.
DC Disconnect
DC Disconnect detection involves measurement of current. Naturally, a disconnected PD stops consuming current, which
can be inspected by the PSE. The PSE must therefore disconnect power within 300 to 400 ms from the current flow stop.
The lower time boundary is important to prevent shutdown due to random fluctuations.
AC Disconnect
This method is based on the fact that when a valid PD is connected to a port, the AC impedance measured on its terminals
is significantly lower than in the case of an open port (disconnected PD).
AC Disconnect detection involves the induction of low AC signal in addition to the 48 VDC operating voltage. The returned
AC signal amplitude is monitored by the PSE at the port terminals. During normal operation, the PD's relatively low
impedance lowers the returned AC signal while a sudden disconnection of this PD will cause a surge to the full AC signal
level and will indicate PD disconnection.

7. TROUBLESHOOTING
This chapter contains information to help you solve problems. If the Switch is not functioning properly, make sure the
Ethernet Switch was set up according to instructions in this manual.
The Link LED is not lit
Solution:
Check the cable connection and remove duplex mode of the Switch.
Some stations cannot talk to other stations located on the other port
Solution:
Please check the VLAN, port trunking function that may introduce this kind of problem.
Performance is bad
Solution:
Check the full duplex status of the Ethernet Switch. If the Ethernet Switch is set to full duplex and the partner is set to
half duplex, then the performance will be poor.
100Base-TX port link LED is lit, but the traffic is irregular
Solution:
Check that the attached device is not set to dedicate 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 switch .Try another port on the 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 power again.
