Can't find the NWSP on the network anymore

After a power cut I can't find the NWSP anymore.
LED on the front is blue. LEDs on the NIC are both on. Right one is blinking...
I tried to find the NAS with the fvdw-sl-assistant and by running a ping sweep on the network.
Any other ideas to reconnect to the NAS without having to open it?
Thanks!
