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.

1.1 Package Contents

• One 16-port Switch
• One AC power cord
• Two rack-mount kits and screws
• This user's guide
• One console cable
  

Section 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:

You can also install this 16-port Switch in a 19" rack with rack-mount kits as shown below:

SECTION 3

Configure the Network Connection

3.1 Connecting Devices to the 16-port Switch

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.

SECTION 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.

SECTION 5

LEDs Conditions Definition

5.1 Adding 100BaseFX Module

The LEDs provide useful information about the switch and the status of all individual ports.

SECTION 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 receive data from each other. Even broadcast packets can not be transferred between VLANs. So, the VLAN function is often used for the 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.

{tc "4.3 Resolving Overload Network Problems"}

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.

SECTION 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.

(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 an tag/untagged of ports.

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.

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

You can change password with this function.

(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

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.
