„
RJ-45 Ports (Auto MDI/MDIX): 24 x 10/100 N-way auto-sensing for
10Base-T or 100Base-TX connections.
In general, MDI means connecting to another Hub or Switch while MDIX
means connecting to a workstation or PC. Therefore, Auto MDI/MDIX would
allow connecting to another Switch or workstation without changing
non-crossover or crossover cabling.

2 Giga port: The traditional RJ-45 ports can be used for up-linking wide-band
paths in short distance (<100m), or the appropriate replaceable mini-GBIC
ports can be used for the application of wideband up-linking and long
distance transmissions to fit the flexible field request.
[NOTE]
When the Mini-GBIC slot and the corresponding RJ-45 port are both
being connected, the Mini-GBIC (Giga fiber) port has higher priority.

Desktop Installation
Set the switch on a sufficiently large flat space with a power outlet nearby. The
surface where the user put the switch should be clean, smooth, level and sturdy.
Make sure there is enough clearance around the switch to allow attachment of
cables, power cord and allow air circulation.
Attaching Rubber Pads
A. Make sure mounting surface on the bottom of the switch is grease and dust
free.
B. Remove adhesive backing from your Rubber Pads.
C. Apply the Rubber Pads to each corner on the bottom of the switch. These
footpads can prevent the switch from shock/vibration.
Rack-mounted Installation
The ES-5226RS comes with a rack-mounted kit and can be mounted in an EIA
standard size, 19-inch Rack. The switch can be placed in a wiring closet with
other equipment.
Perform the following steps to rack mount the switch:
A. Position one bracket to align with the holes on one side of the switch and
secure it with the smaller bracket screws. Then attach the remaining bracket
to the other side of the switch.
B. After having attached mounting brackets, position the ES-5226RS in the rack
by lining up the holes in the brackets with the appropriate holes on the rack.
Secure the switch to the rack with a screwdriver and the rack-mounting
screws.

For proper ventilation, it allows about at least 4 inches (10 cm) of
[NOTE]
clearance on the front and 3.4 inches (8 cm) on the back of the Switch. This
is especially important for enclosed rack installation.
Power On
Connect the power cord to the power socket on the rear panel of the Switch. The
other side of power cord connects to the power outlet. The internal power supply
of the Switch works with voltage in the range of 100-240VAC and Frequency of
50~60Hz. Check the power indicator on the front panel to see if power is properly
supplied.

Network Application
This section provides you a few samples of network topology in which the switch
is used. In general, the ES-5226RS is designed as a segment switch which with
its large address table (4k MAC address) and high performance, it is ideal for
interconnecting networking segments.
PC, workstations, and servers can communicate each other by directly
connecting with ES-5226RS. The switch automatically learns nodes address,
which are subsequently used to filter and forward all traffic based on the
destination address.
By using Uplink port, the switch can connect with another switch or hub to
interconnect other small-switched workgroups to form a larger switched network.
Meanwhile, the user can also use fiber ports to connect switches. The distance
between two switches by connecting with fiber cable can be up to 550 m
(multi-mode fiber) or 10 kilometer (single-mode fiber).
Small Workgroup
The ES-5226RS can be used as a standalone switch to which personal
computers, server, printer server, are directly connected to form a small
workgroup.

VLAN Setting
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast
domain, which would allow you to isolate network traffic, so only the members of
the same VLAN will receive traffic from the ones of the same VLAN. 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 plugged into the same switch physically.
VLAN Member Setting (Port Based)
The switch provides port based VLAN configuration. Users can enable the
function via VALN member setting. That is a set of ports allowed to be forwarded
from the source port. The overall number of VLAN groups that this switch can
support is 26.

VLAN Mode
Tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is
possible to create a VLAN across devices from different switch venders. IEEE
802.1Q VLAN uses a technique to insert a “tag” into the Ethernet frames. Tag
contains a VLAN Identifier (VID) that indicates the VLAN numbers. Please notice
that this page is only for Tag Based VLAN.

¾
Uplink: In normal operation, if the destination and source are located in
different VLANs, the packets will be dropped. Having ticked the radio
button, the port is configured as an up-link port which is used in an
application such as virus check or firewall. For example, the two up-link
ports are located in different VLANs and are connected to a virus check
station or firewall. The virus check station or firewall will check whether the
packet contains the virus pattern. If not containing the virus pattern, this
packet will be forwarded to the up-link port located in different VLANs.
¾ AddTag: A tag port always adds a tag to a forwarded packet with VID
selected by PVID.
¾ Don’t care: If the NIC of a PC doesn’t support 802.1Q VLAN tagging,
select this radio button to ignore the packets tagged.
¾
RemoveTag: An un-tagged port always removes a tag from a forwarded
packet.

VLAN PVID Index Setting
The switch supports a 32-entry VLAN table to provide 32 active VLANs out of
4096 VLANs defined in IEEE802.1Q. User can define 32 VID entries in the VID
table and enable the tag VLAN function. When a tagged packet is received, the
switch compares the VID field in the packet with the ones defined in the VID table.
If it is not matched, the switch drops the packet. If it is matched, the switch uses
the corresponding index to select one of the 32-entry in the VLAN table as an
output port mask. That is, a set of ports, to which the packet can be forwarded to.
The switch forwards the packet according to MAC address and the output port
mask. If the source port is not one of the members in the VLAN table entry, the
switch drops the packet.
When an un-tagged packet is received, the switch uses the default PVID for the
source port as index to the VID of the packet. The switch forwards the packet in
the same way as mentioned above.

QoS Setting
Here you can configure QoS policy priority mode and CoS (Class of Service)
configuration. QoS (Quality of Service) refers to mechanisms in the network
software that make the actual determination of which packets have priority. CoS
refers to feature sets, or groups of services, that are assigned to users based on
company policy. If a feature set includes priority transmission, then CoS winds up
being implemented in QoS functions within the routers and switches in the
network. In an enterprise network, class of service (CoS) differentiates
high-priority traffic from lower-priority traffic. Tags may be added to the packets to
identify such classes, but they do not guarantee delivery as do quality of service
(QoS) functions, which are implemented in the network devices.

Priority Mode
There are three priority modes available to specify the priority of packets being
serviced. Those include First-In-First-Out, All-High-Before-Low, and
Weight-Round-Robin.
„
„
„
First-In-First-Out: Packets are placed into the queue and serviced in the
order they were received.
All-High-Before-Low: The packets of low weight will be serviced after all of
the packets of high weight are serviced.
Weight-Round-Robin: All queues are serviced round-robin: a packet from
one queue, a packet from the next and so on. Similar to round-robin, WRR
(Weight-Round-Robin) means packets are accessed round-robin style, but
weight can be given priorities. For example, four packets from a high weight
might be serviced, followed by two from a low weight.

Class of Service Configuration
Class of Service (CoS) is a 3-bit field within a layer two Ethernet frame header
using IEEE 802.1Q. Class of Service (CoS) is a way of managing traffic in a
network by grouping similar types of traffic (for example, e-mail, streaming video,
voice, large document file transfer) together and treating each type as a class with
its own level of service priority. Unlike Quality of Service (QoS) traffic
management, Class of Service technologies do not guarantee a level of service in
terms of bandwidth and delivery time; they offer a "best-effort."

Trunk
Port trunk allows multiple links to be bundled together and act as a single physical
link for increased throughput. It provides load balancing, and redundancy of links
in a switched inter-network. Actually, the link does not have an inherent total
bandwidth equal to the sum of its component physical links. Traffic in a trunk is
distributed across an individual link within the trunk in a deterministic method that
called a hash algorithm. The hash algorithm automatically applies load balancing
to the ports in the trunk. A port failure within the trunk group causes the network
traffic to be directed to the remaining ports. Load balancing is maintained
whenever a link in a trunk is lost or returned to service. This switch may use Port
ID, Source MAC Address, Destination MAC Address, or a combination of Source
MAC Address and Destination MAC Address to be the selection for Trunk Hash
Algorithm. Traffic pattern on the network should be considered carefully before
applying it. When a proper hash algorithm is used, traffic is kind of randomly
decided to be transmitted across either link within the trunk and load balancing will
be seen.

Trunk Hash Algorithm Selection: Click on the radio button to choose the
method for trunk hash algorithm.
When trunk type is set in LACP mode, the trunk group is using LACP which allows
bundling several physical ports together to form a single logical channel. A port
which joins an LACP trunk group has to make an agreement with its member ports
first. LACP allows a network switch to negotiate an automatic bundle by sending
LACP packets to the peer. LACP is a protocol implementation in OSI layer 2 which
controls through which physical links the traffic will be routed.
Set the trunk type in Static mode to configure the trunk group as a static one. The
advantage of static mode is that a port joins the trunk group without any
handshaking with its member ports. But member ports won’t know that they should

Troubleshooting
This section is intended to help the user solve the most common problems on the
ES-5226RS.
Incorrect connections
The switch port can auto-detect straight or crossover cable when the user links
switch with other Ethernet device. The RJ-45 connector should use correct UTP
or STP cable. 10/100Mbps ports use 2 pairs twisted cable and Gigabit 1000T
ports use 4 pairs twisted cable. If the RJ-45 connector is not correctly pinned on
right position then the link will fail. For fiber connection, please notice that fiber
cable mode should match the fiber module.
„
Faulty or loose cables
Look for loose or obviously faulty connections. If they appear to be OK, make sure
the connections are snug. If that does not correct the problem, try a different
cable.
„
Non-standard cables
Non-standard and miss-wired cables may cause numerous network collisions and
other network problem, and can seriously impair network performance. A
category 5-cable tester is a recommended tool for every 100Base-T network
installation.

„
Improper Network Topologies
It is important to make sure that users have a valid network topology. Common
topology faults include excessive cable length and too many repeaters (hubs)
between end nodes. In addition, the user should make sure that the network
topology contains no data path loops. Between any two ends nodes, there should
be only one active cabling path at any time. Data path loops will cause broadcast
storms that will severely impact the network performance.
Diagnosing LED Indicators
To assist in identifying problems, the switch can be easily monitored through
panel indicators, which describe common problems the user may encounter and
where the user can find possible solutions.
If the power indicator does turn on when the power cord is plugged in, the user
may have a problem with power outlet, or power cord. However, if the switch
powers off after running for a while check for loose power connections, power
losses or surges at power outlet. If the problem still cannot be resolved, please
contact the local dealer for assistance.
„
Cabling
RJ-45 ports: Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP)
cable for RJ-45 connections: 100Ω Category 3, 4 or 5 cable for 10Mbps
connections or 100Ω Category 5 cable for 100Mbps connections. Also be sure
that the length of any twisted-pair connection does not exceed 100 meters (328
feet). Gigabit port should use Cat-5 or cat-5e cable for 1000Mbps connections.
The length does not exceed 100 meters.
