Hi, If you are creating only Layer 2 VLANs on the switch , you wont be able to ping the servers and Routers as they are in default VLAN1. you can do the below steps 1. Create sub interfaces on the router LAN interface 2. Provide a new ip range to the new sub interface 3. Make the switch port connecting router as trunk, so that it will carry both the VLAN info 4. on your Labtop/PC give the IP address in the newly defined range 5. Make your switch port to be in the new VLAN
This will work , if you wont be able to configure the above settings, let me know i will give you the detailed config
You haven't supplied any detail on exactly what "not working" means. If you get lights when you plug something in but nothing can connect, it may have features such as Vlan enabled. Can you get to the administration console to reset to factory defaults? Otherwise google to find the user manual and perform a factory reset. Here is one link I found:
What do you need it configured to support? Multiple subnets? VoIP support? Here's an example to support 2 subnets, VLAN 1 Data and VLAN 2 Voice. This switch is the VLAN router for the site and it is also the default gateway for all the devices on the network.

First, be sure to assign an ip address(in the proper subnet) to each VLAN.
Second, use the ip helper-address command in the context of each VLAN, the address used should be the address of the DHCP server
Third, Add a scope for each additional VLAN on the DHCP server.
The switch will route the DHCP request to the proper server based on the ip helper-address command parameter and based on the ip address of the VLAN that is passed tot he server, a DHCP address in the proper subnet is automatically configured.
can you clarify the switch configuration, by default it will have all ports as untagged in the default vlan 1 with a bootp/dhcp address, I assume you will need to perform some kind of routing ie; default gateway, ip-helper address or static route to point to your routing device ADSL router etc try the following;
1~ configure an ip helper address on vlan 1 to point to what ever is supplying dhcp
2~ create a defualt route on the switch ie; 0.0.0.0 0.0.0.0 to next hop / routing device
3~ configure a default gateway ie; ip default-gateway x.x.x.x where x= routing device
the above can be accomplished via a serial connection to the switch using hyperterminal with the following settings
bits per second 9600
data bits 8
stop bits 1
flow control none
