bit defender box 2 replacement red light

After replacing my Bitdefender Box 2 with another BB2 I can not delete the old one (it does not work anymore electric surge) from my net.

I configured new other BB2, but all I get is red light. I have active subscription to BB2 and I want to update the my now BB2 with my active subscription (from before with an older BB2).


Thank You in advance, sincerely, Grega
