ESD Procedures
Caution This is a class I unit. In Denmark, use this unit with an AC cord suited to Danish specifications. The cord
should include an earthing conductor. Plug the unit into a wall socket outlet which is connected to the
protective earth contact. Do not use socket outlets which are not connected to a protective earth contact!
High Voltage
Disconnect the Cisco Unified Videoconferencing 3545 chassis from the power line before removing the
cover. Avoid any adjustment, maintenance, or repair of an opened chassis under voltage. These actions
should only be carried out by a skilled person who is aware of the dangers involved. Capacitors inside
the chassis may still be charged, even if the unit has been disconnected from the power source.
Power Supply
Caution Risk of electric shock and energy hazard. Disconnecting one power supply disconnects only one power
supply module. To isolate the unit completely, disconnect all power supplies.
ESD Procedures
To prevent damage to Cisco element boards by random electrostatic discharge (ESD), the use of wrist
straps is highly recommended.
