Section 1 - Safety Instructions • Observe extension cable and power strip ratings. Make sure that the total ampere rating of all products plugged into the extension cable or power strip does not exceed 80 percent of the ampere ratings limit for the extension cable or power strip. • To help protect your system from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS). • Position system cables and power cables carefully; route cables so that they cannot be stepped on or tripped over. Be sure that nothing rests on any cables. • Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modifications. Always follow your local/national wiring rules. • When connecting or disconnecting power to hot-pluggable power supplies, if offered with your system, observe the following guidelines: - Install the power supply before connecting the power cable to the power supply. - Unplug the power cable before removing the power supply. - If the system has multiple sources of power, disconnect power from the system by unplugging all power cables from the power supplies. • Move products with care; ensure that all casters and/or stabilizers are firmly connected to the system. Avoid sudden stops and uneven surfaces. D-Link DGS-2208 User Manual 5
