Hp rx2620: is possible to access ILO via serial COM1?

Fast question: a bad reset put ilo ip to 127.0.0.1(!)
and now i cannot reach via network
Is possible to get ilo via serial using COM1/console?
I see three console ports on server back side
two are standard and one is reachable only with this cable...
403 Forbidden
but i don't have this cable.
Question is: there is a way to get ilo access via standard com1/console?
