1. Introduction
The Model S71650 16-port Switch is a 16-port 10/100Mbps Fast Ethernet switch. This switch
supports the advanced features for current switch design. This switch can auto detect
10/100Mbps speed, full/half duplex mode, MDI/MDI-X connection and provides an option for
one 100BaseFX expansion module port. This feature provides the user a simple way to complete
the network connection with the switch.
The Model S71650 16-port Switch provides console management functions. You can configure
VLAN, trunking and port configuration from the console which provides more flexible network
management and configuration functions.
The Model S71650 16-port Switch supports 4 priority transmit queues per port and long Ethernet
packets of up to 1522 bytes for QoS function for advanced network applications.

2. Installation
2.1 Where to Place the 16-port Switch
This 16-port Switch can be placed on a flat surface (your desk, shelf or table).
Place the 16-port Switch at a location with these connection considerations in mind:
•The switch configuration does not break the rules as specified in Section 3.
•The switch is accessible and cables can be connected easily to it.
•The cables connected to the switch are away from sources of electrical interference such as
radio, computer monitor, and light fixtures.
•There is sufficient space surrounding the switch to allow for proper ventilation (the switch
may not function according to specifications beyond the temperature range of 0 to 50
degrees C).
You can also install this 16-port Switch in a 19" rack with rack-mount kits as shown below:

3. Configure the Network Connection
3.1 Connecting Devices to the 16-port Switch
•Use Category 3 or 5 twisted-pair Ethernet cable when connecting 10BaseT devices to the
switch (cable pin assignments defined in Appendix A)
•Use Category 5 (straight-through) twisted-pair Ethernet cable when connecting 100BaseTX
devices to the switch (cable specifications defined in Appendix B)
•Always limit the cable distance to 100 meters (328 ft) as defined by IEEE specification
•If your switch has a FX port, you can connect long distance fiber optic cable to the switch.
•Because this switch supports Auto MDI/MDI-X detection, you can use normal straight
through cable for both workstation connection and hub/switch cascading.
3.2 Connecting to Another Ethernet Switch/Hub
This 16-port Switch can be connected to existing 10 Mbps or 100 Mbps hubs/switches. Because
all of the TP ports on the 16-port Switch are Auto MDI/MDI-X, you can connect from any TP
port of the 16-port Switch to the MDI or MDI-X port of another hub/switch with Straight
Through or crossover cables.

3.3 Application Example
A switch can be used to overcome the hub-to-hub connectivity limitations as well as improve the
overall network performance. Switches make intelligent decisions about where to send network
traffic based on the destination address of the packet. As a result, the switch can significantly
reduce unnecessary traffic.
The example below demonstrates the switch ability to segment the network. The number of
nodes on each segment is reduced thereby minimizing network contention (collisions) and
boosting the available bandwidth per port.

4. For 100BaseFX Module
4.1 Adding 100BaseFX Module
This 16-port switch has a module port for a 100BaseFX connection extension. You can add one
100BaseFX module to the switch for long distance fiber optic cable connection. But when this
module is added, the 16th TP port will be disabled and this FX port becomes the 16th port.
Please follow the steps to add the module to the switch:
1. Turn off the switch
2. Loosen the screws of the blank cover and remove the cover from the module port of the
switch.
3. Slide in the module into the module port.
4. Tighten the screws of the module to the switch.
5. Connect the fiber optic cable to the FX port of the module.
6. Power on the switch.
7. Refer to Section 7 to configure Port 16 to 100Mbps, full duplex.

6. About VLAN and QoS
6.1 VLAN
The VLAN setting of a switch can divide the switch to several switching segments. The network
connections on different VLANs can not send or receiver data from each other. Even broadcast
packets can not be transferred between VLANs. So, the VLAN function is often used for user's
security application.
Here are two examples for VLAN applications.
The first one is called Concentration VLAN setting. In this case, Port (1,16), (2,16), (3,16),
(4,16), …, (13,16), (14,16), (15,16) are in different VLANs and Port 16 is the common port for
uplink or Internet connection. But the data transfer between Port 1, 2, 3, 4, …, 13, 14 and 15 are
impossible for such configuration.
The second one is the default VLAN setting of the switch. Every port belongs to the same
VLAN and can communicate with each other.
Please refer to Section 7 to configure the VLAN from the console port.
6.2 QoS
In new network application, there is a tag in the Ethernet packet. The tag contains VLAN and
priority information of the packet. This 16-port Switch can process both tagged and untagged
packets at ingress ports. If there is a tag in an Ethernet packet, it can transmit the packet
according to the priority of the packet in the tag.
There are 4 transmit queues for each port of the 16-port Switch. This 16-port Switch can transfer
packets according to the priority of the packet to meet the "Quality of Service" request in the
network. It is very important for multi-media data (for example: movie, music and voice)
transfer in a network.
Note: The QoS function is not configurable and is defined in the switch controller.

7. Configure from Console Port
(1) Setup Hardware and Software for Configuration
Hardware setup
Connect from the console port of the Switch to COM port of PC with the console cable.
Software setup
1. PC is running MS Windows.
2. Start -> Program -> Accessory -> Terminal. Execute "Hypertrm" program. If you cannot
find the Terminal program, please install it from your MS Windows installation disk.
3. If the connection file has been created, cancel the new connection request and open the
connection file. If the connection file has not been created, create a new connection
named "SW16" -> Select COM port of PC -> Set COM port parameters as "Baud Rate:
9600, Data Bits: 8, Parity Check: None, Stop Bit: 1, Flow Control: None". Then OK.
4. Power on the Switch and the setup console will appear as follow.
5. The default password is "1234" (you can change it in the console setting). The main
screen will appear if the password is correct.
[Notes:] If you can not get the console screen, please reboot the switch or close the terminal
program and start again.

9www.versitron.com
(2) Configure Connection Ports of the Switch
1. Users can enable/disable auto-negotiation, flow control and auto-MDIX functions of the
connection ports with this function. If auto-negotiation is disabled, users can set the
connection speed, full/half duplex of the connection ports. The default setting is auto-
negotiation enable.
2. Follow the direction in the setup menu to setup the configuration of the connection ports.
(3) Setup VLAN Groups of the Switch
1. Select VLAN setup function in the main menu as follows:
Note: Before starting to set VLAN, the trunking function will be disabled first. After
VLAN setup is completed, you may set the trunking function if you need trunking
connection on the switch.
2. You can select the quick setup item for Concentration VLAN or the other VLAN
configuration. If you want to use concentration VLAN, use function 1 and select which
port is the common port for the concentration VLAN. The software will create
concentration VLAN configuration automatically. (You may refer to Section 6.1 for
concentration VLAN configuration.)
3. If you want to configure VLAN by yourself, use function 2 to setup VLAN group and
PVID of ports. Use "VLAN Setup" to create VLAN groups first. Then set PVID and
tag/untagged of ports.

10 www.versitron.com
4. If you want to configure VLAN by yourself, use function 2 to setup VLAN group and
PVID of ports. Use "VLAN Setup" to create VLAN groups first. Then set PVID and
tag/untagged of ports.
m: modify setting of VLAN group. Select the VLAN group first and the connection port.
Then select the operation - add or remove the port to/from the VLAN.
a: add ports to VLAN. Select the VLAN group first and then select the ports to add to
the VLAN group.
d: delete VLAN group. This function will delete one VLAN group.
q: quit from this function. "Save & Update (Y/N)" message will be prompted to ask you
if you want to save and update to this new setting.
5. Then, we use "PVID Setup" function to set the PVID of ports.
After you complete the VLAN groups setup, you have to set the PVID of ports to the
VLAN ID of their VLAN group. If port overlapping happens, please assign the PVID of
the overlapped port to the VLAN ID that it will use for packet transmitting VLAN
grouping.
If tagged packets, VLAN ID is in the tag of the packets. If untagged packets, the switch
will assign PVID to the packet as its VLAN ID. And the switch will check the VLAN
group setting with the VLAN ID. If they belong to the same VLAN, the packets will be
forwarded. If they belong to different VLANs, the packets will be filtered out.
Note:Because this switch supports VLAN ID 0~15 only, the switch will use bit 0~3 of the
VLAN ID as its VLAN ID if the VLAN ID in the tagged packets are larger than 15.

11 www.versitron.com
5. You can use command "m" to set ports to tag or untagged and set PVID of ports. The
output packets from a tag port will always be tagged packets. If untagged packets, tag
will be added before these packets are transmitted. And the output packets from
untagged port will always be untagged packets. If tagged packets, the tag will be
removed before these packets are transmitted.
The tag or untagged setting depends on your applications in the network. If you are not
sure about your network application, you may set all of them to untagged because many
old network devices do not support long Ethernet packets with a tag (tag is another 4
bytes added to normal Ethernet packets).
Notes: Data will only be forwarded to ports in the same VLAN group. Data will not be
forwarded to ports in different VLAN groups, as if they were not connected together. The
factory default setting of the switch is all ports are in the same VLAN group.
(4) Setup Trunking Connection of the Switch
1. Enter the Trunk setup function in the main menu as follows:
2. This switch supports two trunks and two ports per trunk maximum. You can select the
trunk and enable or disable it in this setup function.
Notes: Before you enable the trunk, please check the VLAN setting of the ports used
for the trunk. They must belong to the same VLAN group and have the same PVID
and tag/untagged setting. If they are different on some items, please make them
have the same configuration first.
(5) Change Password
1. You can change password with this function.

12 www.versitron.com
(6) Advanced Setup
There are three advanced functions for switch you can setup here:
1. Port Locking
In the Port Locking function, you can allow only one user to use the network connection
of some port through the switch. There could be two different lock operations for the
switch.
Static Lock: If the "Switch Aging" function of the switch in "Broadcast Storm Filter"
setup is set to disable, only the user that the switch learns firstly on that port can use this
connection port even if the user turns OFF his PC.
Dynamic Lock: If the "Switch Aging" setting is enable, another user with other Mac ID
could be the "only-one" user for the port after last user is OFF and his MAC ID is aged
out.
2. Broadcast Storm Filter
You can enable/disable the aging and broadcast storm filtering functions of the switch
from this function.
If the broadcast storm filtering function is enable, the broadcast packets over the rising
threshold within 50ms will be discarded. You can set three threshold levels (per port) for
broadcast storm.
1: 10% for all 100TX, 1% for not all 100TX
2: 20% for all 100TX, 2% for not all 100TX
3: 40% for all 100TX, 4% for not all 100TX

13 www.versitron.com
3. CoS (Class of Service)
There are 4 transmit queues per port in the switch to support CoS function and you
configure the CoS function of the switch with this function.
1. Global
Because this switch can perform CoS function with Port-base, VLAN-base or TOS-
base, you can configure it with this function.
TOS Over VLAN priority: If enabled, the priority information in TOS will be
processed first then priority information in VLAN tag. If disabled, the priority
information in VLAN tag will be processed first.
Port-Base Priority: If enabled, all the packets received from this port will be always
sent with the assigned priority and the priority information in VLAN tag and TOS
will be ignored.
Port Priority: Assign the transmit priority of packets received from the port if "Port-
Base Priority" is enabled.
2. VLAN/TOS Priority Map
You can map the priority value in VLAN/TOS to the four transmit queues with this
function.
There could be eight different priority values in VLAN tag and TOS and these values
will be mapped to the four transmit queues in each port of the switch. You can
arrange the mapping here.

(7) Restore Default Setup
You can restore the configuration to the default setting with this function.
(8) Exit
You can exit this setup interface with this function and it will go back to the login screen.
