Electrical Safety for the 3545 MCU
To avoid an electric shock or damage to the Cisco Unified Videoconferencing 3545 System, servicing
should be performed by qualified service personnel only.
To reduce the risk of damaging power surges, Cisco recommends installing an AC surge arrestor in the
AC outlet from which the Cisco Unified Videoconferencing 3545 System is powered.
Warning
Changes or modifications to the device that are not approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
Warning
There is a danger of explosion if the cPCI board battery is incorrectly replaced. Replace with the same
type, or an equivalent type recommended by the manufacturer. Dispose of used batteries only
according to manufacturer instructions.
Grounding
The power cable of the Cisco Unified Videoconferencing 3545 System should only be connected to a
power outlet that has a protective earth contact. Do not use an extension cord that does not have a
protective conductor (ground). The Cisco Unified Videoconferencing 3545 chassis can become
dangerous if you interrupt any of the protective conductors (grounding) or disconnect any of the
protective earth terminals.
