WIZ1000 - no communication.


I have encountered a problem with WIZ1000. After powering on the device (with plugged in Ethernet cable and serial cable) thеre is no link activity (all the LEDs are dark, except for power), no serial communication and the config tool cannot find the device on the network (I have set up the router to give the exact IP subnet needed for the device 192.168.11.xxx).
Does any of you encountered such problem ? Any help on this matter will be highly appreciated.
