SMC EX500-GEN1 (Ethernet/IP)

Hi, guys. I need some help. I had SMC gateway unit EX500, but not so long ago it was replaced with the new gateway unit, the same one. Now i have to set up the IP-adress for this new gateway unit. In RSWho i have this:

What does this red cross mean? And how can i set the IP? I tried to set it using BootP/DHCP Server, but there weren't requests from a new device, so i couldn't even see its MAC.
Have so much trouble with it) Please, help!)

SOLVED! Everything works just fine) All i needed was a bit of luck)
P.S. Finally i set the IP via BootP/DHCP Server.

Hi there,
sorry to jump on old post, but how did you do it exactly,
i have a unit that died on me so i replaced it, but i dont get the request in bootp, i even tried setting dip switches to enable dhcp mode but nothing,

any tips will be greatly appreciated,
