DPA 7630

I am trying to add a DPA 7630 gatway to my Octel I am having problems getting DHCP. It is registered with the DHCP scope but my MAC addr. is two digits short. When I try to change it on the DPA it only allows 10 dugits and the SEP at the front of the MAC. I had it getting DHCP and now it will not it is registered on my publisher.
