Warnings Warnings and a caution which appear in this User's Guide are summarized here. Familiarize yourself with these warning before you use and service the cc3310 server. WARNING Anchor the equipment rack: The equipment rack must be anchored to an unmovable support to prevent it from falling over when one or more servers are extended in front of the rack on slides. You must also consider the weight of any other device installed in the rack. A crush hazard exists should the rack tilt forward that could cause serious injury. If AC power supplies are installed: Main AC power disconnect: The AC power cord(s) is considered the main disconnect for the server and must be readily accessible when installed. If the individual server power cord(s) will not be readily accessible for disconnection then you are responsible for installing an AC power disconnect for the entire rack unit. This main disconnect must be readily accessible, and it must be labeled as controlling power to the entire rack, not just to the server(s). To remove all power, two AC cords must be removed. Grounding the rack installation: To avoid the potential for an electrical shock hazard, you must include a third wire safety ground conductor with the rack installation. If the server power cord is plugged into an AC outlet that is part of the rack, then you must provide proper grounding for the rack itself. If the server power cord is plugged into a wall AC outlet, the safety ground conductor in the power cord provides proper grounding only for the server. You must provide additional, proper grounding for the rack and other devices installed in it. Overcurrent protection: The server is designed for an AC line voltage source with up to 20 amperes of overcurrent protection per cord feed. If the power system for the equipment rack is installed on a branch circuit with more than 20 amperes of protection, you must provide supplemental protection for the server. The overall current rating of a server configured with two power supplies is less than 4 amperes. Chapter 1 13

Warnings and a caution which appear in this User’s Guide are summarized here. Familiarize yourself with
these warning before you use and service the cc3310 server.
WARNING
Anchor the equipment rack: The equipment rack must be anchored to an
unmovable support to prevent it from falling over when one or more servers are
extended in front of the rack on slides. You must also consider the weight of any
other device installed in the rack. A crush hazard exists should the rack tilt forward
that could cause serious injury.
If AC power supplies are installed:
Main AC power disconnect: The AC power cord(s) is considered the main disconnect
for the server and must be readily accessible when installed. If the individual server
power cord(s) will not be readily accessible for disconnection then you are
responsible for installing an AC power disconnect for the entire rack unit. This
main disconnect must be readily accessible, and it must be labeled as controlling
power to the entire rack, not just to the server(s). To remove all power, two
AC cords must be removed.
Grounding the rack installation: To avoid the potential for an electrical shock
hazard, you must include a third wire safety ground conductor with the rack
installation. If the server power cord is plugged into an AC outlet that is part of the
rack, then you must provide proper grounding for the rack itself. If the server
power cord is plugged into a wall AC outlet, the safety ground conductor in the
power cord provides proper grounding only for the server. You must provide
additional, proper grounding for the rack and other devices installed in it.
