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.
