Auto switchingredundant power supplies and a redundant storage system protect against failure. Multilevelauthentication methods and automatic backup of all system and accounting data ensuremaximum reliability and management peace of mind. The Switch meets FCC requirements in47 CFR Part 15 for personal computers and peripherals designated for business use (ClassA),and is labeled in accordance with FCC requirements.The Contivity™ Extranet Switch 4500 is entirely encased by a thick steel chassis. The systemhas three removable portions: the front bezel, the top cover, and the I/O Panel. Removing the
