You'll loose the antenna, arrestor, cable and bridge, but that is much better then your $30K core router. You also want to make sure the media convertors are on seperate UPS and if possible circuits. Electricity is a smart little beast and will flow through the circuits in walls and seek and destroy your NOC. -- Bob Tanner <tanner at real-time.com> | Phone : (952)943-8700 http://www.mn-linux.org, Minnesota, Linux | Fax : (952)943-8500 Key fingerprint = 6C E9 51 4F D5 3E 4C 66 62 A9 10 E5 35 85 39 D9
