Here is a link to the manuals available for the Dell PowerConnect 62xx:

Creating VLANs
console> enable
console# config
console(config)# vlan database
console(config-vlan)# vlan 10
console(config-vlan)# exit
console(config)# interface vlan 10
console(config-if)# ip address 192.168.10.x 255.255.255.0
console(config-if)# name Marketing
console(config-if)# end
console# show vlan
Creating Ports for PC to connect as VLAN unaware host.
console> enable
console# config
console(config)# interface ethernet 1/e1
console(config-if)# switchport mode access
console(config-if)# switchport access vlan 10
console(config-if)# end
Enable routing
To globally enable IPv4 routing on the router, use the "ip routing" command
in Global Configuration mode.
console(config)#ip routing
You will need to create the VLANs as described above. Then set ports in access mode for a particular VLAN then set the PC with an IP address in the range of the subnet for the VLAN and gateway as the IP address of the address you provided for the VLAN on the port.
Then once routing is enabled globally it should allow communication between VLANs and different subnets that are configured.
Hope this helps,
