Console Port

The console port is used when you forget the Switch’s IP address.

1. Connect one end of the RS232 Cable came with the product package to the COM port on your PC,

and the other end to the Console port on the Switch.

2. From your computer, run HyperTerminal program. Assign a name and set baud rate at 19200

bps.

3. Power off the Switch and then turn it on. The connection will be established automatically.

4. You can find the IP address of the Switch from the screen.

Notice

: The RS232 cable came with the Switch is a crossover cable. If you would like to use the regular

RS232 cable, please switch pin 2/3, pin 4/6 and pin 7/8.

Power Socket

The Power Socket is designed to be used with the power cord included in the product package.

1. Attach the female end of the power cord to the male power connector on the back panel.

2. Attach the male end of the power cord to a grounded power outlet.

Preparing a PC

Choose a browser-enable PC on LAN where the Switch is located. It is recommended you use

Microsoft Internet Explorer 5.0 or later. Change the computer’s IP settings to conform to Switch’s

default settings, if necessary. The default IP settings of SH2500 switch are as follows.



Default IP Address: 192.168.0.100

 Default Gateway: 192.168.0.254

 Default Subnet Mask: 255.255.0.0

Connect to the Switch

Launch the web browser. On the address bar, type the Switch’s default IP address 192.168.0.100 to

access the Switch.

You will be connected to the Admin Website. Log in using the default user name and password as

below.

Default Username:

admin

(case sensitive)

Default Password: 1234

After you log in, the configuration page will come up as below. Upon selecting any item from the list,

a page with detail information on that item will come up.

Port Status

1. Click “Port Status”, all ports information will come up.

 Link Status – Indicates the link status of each port on/off.

 Speed –Indicates the speed of each port is 10 or 100 Mbps.

 Duplex –Indicates Half duplex or Full duplex connection on each port.

 Flow Control –Indicates Flow Control status of each port enable/disable.

2. For more details about a specific port status, select a specific port and click the “Counters” button,

and the detail information of the port will come up. The port status will be updated every minute.

You can also click the Refresh button to update the status when necessary.

For example, if you want to know the number of packets received or transmitted on port 1, select

port 1 checkbox and click the Counters button.

Port Configuration

You can set the speed, duplex and priority of a specific port in this section.

1. Select Port Config item.

2. Select a specific port to be configured from “Port Number” list, edit the settings.

 Auto Negotiation, Advertise 10M Half, Advertise 10M Full, Advertise 100M Half, Advertise

100M Full – When “Auto Negotiation” is enabled, you can edit the advertise speed of the port.

Notice that if you set all advertise speeds as off, you will disable that specific port.



Speed, Duplex – When “Auto Negotiation” is disabled, you can edit the speed and duplex of

the port.

 TOS over VLAN priority – When enabled, TOS will be superior to VLAN tag. That means

packets with TOS tags will have the priority pass than packets with VLAN tags. When disabled,

VLAN tag will have priority than TOS. To set TOS or VLAN tag queue, please refer to

“VLAN/TOS priority” setting item.

 Port-based Priority, Port Priority Mapping – When enabled, packets transmitted/received on

the port will have the priority than TOS or VLAN tag. You can then set the queue to be high or

low.

3. When finished, click the Apply button.

Note: The priorities the Swith provides include TOS, VLAN tag and Port-based. The sequence is

Port-based, TOS and VLAN tag if all are enabled by accident.

Port-Based VLAN

1. Select Port-based VLAN item.

2. Select a specific port from “Port Number” list.

3. Select members from port 1-24 to form a Port-based VLAN with the specific port you select on

Step 2. You may select or deselect the “Select All” checkbox to help you select members.

4. Click “Apply” to save the configuration.

Important Notice: Please make sure the Port-based VLAN setting must be adapted to all members of

the same Port-based VLAN. For example, if you would like to form port 1 and port 15 as a Port-based

VLAN, first on Port Number 1 VLAN Config, you need to select port 15 as a member. And then on

Port Number 15 VLAN Config, you need to select port 1 as a member. The same member list should

be set to each member’s VLAN Config.

VLAN/TOS Priority

At “Port Config> TOS over VLAN Priority”, you can select the priority to be TOS or VLAN tag. You

can further set the queue in this section.

1. Select VLAN/TOS Priority item.

2. Select the VLAN tag or TOS level and set it to be high or low queue. Both VLAN tag and TOS

provide 8 priority levels from 0 to 7. Do not set them at the same priority otherwise your setting

will be invalid. The priority goes to VLAN or TOS is depending on your setting at “Port Config>

TOS over VLAN Priority”.

3. Click “Apply” to save the configuration.

QoS Configuration

1. Select QoS item.

2. Select the Priority Radio. It is the Low : High ratio. The Switch will reorder the delivery of packets

based on the ratio you set. For example if you set it as 1:2. That means when the Switch sends 1

packet of low queue, it will send 2 packets of high queue.

3. Depending on your QoS preferences (to be Port-based, VLAN tag or TOS), if you set your QoS as

VLAN tag, enable the VLAN tag check. Otherwise you may disable it.

4. Click “Apply” to save.

System Setup

You can modify the Switch IP settings in this section. The default IP settings are:

Default IP address: 192.168.0.100

Default Subnet Mask: 255.255.0.0.

Default Gateway: 192.168.0.254

After you log in, you may change the IP settings after you log in to conform to your local IP

environment.

If your local IP network is under DHCP environment, select “Enable” checkbox to enable DHCP.
