•
Copper Ports Cable Installation
⇒ The switch copper ports support MDI/MDI-X auto-crossover. This enables use of
either straight-through or crossover Cat 5E cables.
⇒ Use Cat. 5 grade RJ-45 copper cables to connect to the copper RJ-45 ports.
⇒ Repeat the above steps, as needed, for each RJ-45 port to be connected.
• Power On
The switch supports 100-240 VAC, 50-60 Hz power supply. The power supply
will automatically convert the local AC power source to DC power. When initial
power is applied, all the LED indicators will light up for a brief period while the
system performs its startup tests. Once the initial tests (‘POST test’) have
completed all except the power LED should return to an off state.
• Firmware Loading
After power on, the boot-loader will load the switch firmware into the main
operational memory. This process will take about 30 seconds. Once completed, the
switch will flash all the LED’s once switch to a ready state.
2-1-2. Cabling Requirements
To help ensure a successful installation and keep network performance at its
optimum level, please take care in using correct Cat5E or greater cabling. Please
ensure that Stranded core runs for no more than 10 meters, and that solid core runs
for a maximum of 100meters. Poor cabling is the most common cause for network
dropouts, or poor performance.

to it. When it is set to Disabled, then there will be no flow control on the port.
In congested situations the switch will drop packets. Default State : Enable
Fig. 4-4
18
4-2-3. VLAN Mode Configuration
The switch supports Port-based VLAN and Tag-based VLAN (802.1q). 16
active VLANs can be support with VLAN ID’s from 1~4094. VLAN configuration is
used to partition your LAN into small broadcast domains (groups). Properly
configuring VLANS can improve your network security and increase network
performance by limiting broadcast propagation.
Function name:
VLAN Mode Setting
Function description:
There are 4 VLAN Modes: Port-based, Tag- based, Metro mode or Disabled.
These are selected from the drop down list. Selecting one will take affect
immediately.
Parameter description:
VLAN Mode:
Disable:
Disable all VLAN functions. This is the default setting.
Port-based:
Port-based VLAN simply groups ports together. Ports within the same
group can talk to each other ports not in the same group are blocked
from communicating. Any port can be a member of more than one
VLAN to enable shared server, internet or uplink ports. This switch can
support up to a maximal of 16 port-based VLAN groups.
Tag-based:
Tag-based VLAN identifies its members by a VID that is included in the
headers of packets sent and received. This is quite different from portbased VLAN, in that Tagged VLANs can exist as groups across multiple
switches in your enterprise where as port VLANS are local only to the
switch that they are defined on. Port ingress (incoming) and egress
(outgoing) rules allow for filtering of packets that don’t conform to your
specific policies on accepting or denying non Tagged packets.
Each tag-based VLAN that is configured must be assigned a VLAN
name and a VLAN ID. Valid VLAN ID’s are from 1 to 4094.
Administrators can create a total of up to 16 Tag VLAN groups.
19
Metro Mode:
Metro Mode is a quick configuration VLAN option designed for Metro
WAN deployment. It uses Port-based VLAN and creates 14 or 15 Portbased VLAN groups.
Fig. 4-5
20
Up-link Port:
This feature is only enabled when the metro mode is selected.
Option 15:
All ports are assigned a unique VLAN with Port 15.
Port 15 ends up a member of 15 VLAN groups, one VLAN for each port.
This secures intra port traffic, but allows all ports access to a single
uplink port(15). Each VLAN has 2 members. 15 VLANS in total.
Option 16:
All ports are assigned a unique VLAN with Port 16.
Port 16 ends up a member of 15 VLAN groups, one VLAN for each port.
This secures intra port traffic, but allows all ports access to a single
uplink port (16). Each VLAN has 2 members. 15 VLANS in total.
Option 15&16:
All ports are assigned a unique VLAN with Port 15 and 16.
Both ports 15 and 16 end up members of 14 VLAN groups, one VLAN
for each port. This secures intra port traffic, but allows all ports access
to both uplink ports (15 and 16). Each VLAN has 2 members. 14
VLANS in total.
Fig. 4-6
21
4-2-4. VLAN Group Configuration
Function name:
VLAN Group Configuration
Function description:
In port-based VLAN mode, this will display the ID – Description - and Members
of existing port-based VLAN groups. If in tag-based VLAN mode, this will
display the ID - Description – VID and Members of the existing tag-based VLAN
group. The switch can only be configured to support either port-based VLAN or
tag-based VLAN. When selecting one of the VLAN modes, the switch will
display the appropriate configuration data as required. You can easily create
and delete VLAN groups by using the <Add Group> and <Delete Group>
function buttons, or click the Group ID directly to edit it.
Parameter description:
ID (Group ID):
When you want to edit a VLAN group, you must select the Group ID field.
Then enter your Tag Based VLAN Group Settings or Port Based VLAN
Group Settings depending on your VLAN mode selection.
Description:
The description defined by administrator is associated with a VLAN group.
VID:
VLAN identifier. Each tag-based VLAN group has a unique VID. It appears
only in tag-based mode.
Member:
This is used to add or delete ports as members of this VLAN. Use the check
box (;) beside the port x to enable it.

<Delete Group> button to delete the group.
Fig. 4-9
24
4-2-5. PVID Configuration
Function name:
PVID Configuration
Function description:
From within this menu users can assign a VID number for each port. The range
of VID numbers is from 1 to 4094. You can also choose ingress filtering rules to
each port. There are two ingress filtering rules which can be applied to the
switch. Ingress Filtering Rule 1 is “forward only packets with VID matching this
port’s configured VID”. Ingress Filtering Rule 2 is “drop untagged frame”.
Parameter description:
Port 1-16:
Port number.
PVID:
The PVID range will be from 1-4094. Before you set a PVID number, ensure
that you have created a Tag-based VLAN with VID of the same number. For
example, if port 1 receives an untagged packet, the switch will apply the
PVID (assume VID 5) to tag this packet, the packet then will be forwarded
as a packet tagged with VID 5.
Rule 1:
Forward only packets with VID matching this port’s configured VID. You can
apply Rule 1 as a way to a given port to filter unwanted traffic. In Rule 1, a
given port checks if the received packet is a member of the VLAN which the
received port has been assign via its PVID. For example, if port 1 receives
a tagged packet with VID=100 (VLAN name=VLAN100), and if Rule 1 is
enabled, the switch will check if port 1 is a member of VLAN100. If it is, then
the received packet is forwarded; otherwise, the received packet is dropped.
Rule 2:
Drop untagged frame. You can configure a given port to accept all frames
(Tagged and Untagged) or just receive tagged only frames. If the former is
the case, then packets either tagged or untagged will be processed. If the
later is the case, only packets carrying a VLAN tag will be processed, all
other packets will be discarded.
Note: If Rule 1 is enabled and port 1, for example, receives an untagged packet,
the switch will apply the PVID of port 1 to tag this packet, the packet then will
be forwarded.
Tag:
This is an egress rule applied on data transmitted out of the port. Select
untag or tag. Tag means that the outgoing packets must carry VLAN tag
headers, select the check box (;). Untag means that the outgoing packets
carry no VLAN tag headers.
25
Untag State:
If this is enabled and the Untag VID matches the VID of the packet, then the
tag would be removed. If enabled without a match, no operation will occur.
If disabled, no operation will occur.
Untag VID:
Valid range is 0~4094.

4-2-6. Aggregation Configuration
The Aggregation (Port Trunking) Configuration is used to configure Link
Aggregation. You can bundle more than one port with the same speed, full duplex
and the same MAC to be a single logical port, thus the logical port aggregates the
bandwidth of these ports. This allows you to create a higher speed uplink or
backbone connection via bandwidth aggregation. For example, if there are three
Fast Ethernet ports aggregated in a logical port, then this logical port has bandwidth
three times as high as a single Fast Ethernet port has.
Function name:
Aggregation Configuration
Function description:
Display the current setup of Aggregation/Trunking. With this function you can
add a new trunk group or modify the members of an existing trunk group.
Parameter description:
Normal:
Define ports that will not participate in any aggregation/trunking group.

the traffic passed by Port B to be copied to Port A for monitoring purposes.
Parameter description:
Sniffer Mode:
Used for the activation or de-activation of the Port Mirror function. Default is
disable.
Sniffer Port:

28
4-2-8. Quality of Service Configuration
The switch offers powerful QoS functions including: VLAN tagged priority for 8
levels, TOS field IP header (equal DSCP low 3 bits) on Layer 3 network framework,
6 types of layer 4 network transmission events, and IP DiffServe QoS services.
In the Quality of Service (QoS) Configuration there is an option named ”Default
Class”. Once you have selected one of the four QoS methods, this Default Class is
used to group packets that do not match any of the QoS rules defined for the
particular QoS method selected. For instance, if you set the QoS function as VLAN
Tag Priority mode, and then choose Default Class as High, the priority of the
packets with no tags will be considered as High priority precedence. The initial
value of the Default Class is High.
Fig. 4-13
Function name:
VLAN Tag Priority
Function description:
VLAN tags have 3 bits that belonging to a priority flag. These 3 bits can define 8
traffic classifications. These classifications can then be mapped to High priority
or Low priority queues. Packets tagged as High priority will be forwarded over
packets with a low priority when the destination port is in a congested state.
