Hot surfaces Allow the equipment's internal components and hot-pluggable drives to cool before touching them. Object entry Never push a foreign object through an opening in the product. Precautions for portable computer products In addition to the general precautions described earlier, be sure to observe the following precautions when operating a portable computer product. Failure to observe these precautions could result in fire, bodily injury, and damage to the equipment. WARNING! To reduce the possibility of heat-related injuries or of overheating the computer, do not place the computer directly on your lap or obstruct the computer air vents. Use the computer only on a hard, flat surface. Do not allow another hard surface, such as an adjoining optional printer, or a soft surface, such as pillows or rugs or clothing, to block airflow. Also, do not allow the AC adapter to contact the skin or a soft surface, such as pillows or rugs or clothing, during operation. The computer and the AC adapter comply with the user-accessible surface temperature limits defined by the International Standard for Safety of Information Technology Equipment (IEC 60950). Monitor support cover Do not place a monitor with an unstable base or a monitor heavier than the marked weight rating on top of a monitor support cover or stand. Heavier monitors should be placed on a work surface next to the docking base. Rechargeable battery pack Do not crush, puncture, or incinerate the battery pack or short the metal contacts. In addition, do not attempt to open or service the battery pack. Docking base To avoid pinching your fingers, do not touch the rear of the computer when docking it into a base. Precautions for server and network products In addition to the general precautions described earlier, be sure to observe the following precautions when operating server and network products. Failure to observe these precautions could result in fire, bodily injury, and damage to the equipment. Safety interlocks and enclosures To prevent access to areas containing hazardous energy levels, some servers are provided with safety interlocks that disable the power supply when the enclosure cover is removed. For servers provided with safety interlocks, observe the following precautions: ● Do not remove enclosure covers or attempt to defeat the safety interlocks. ● Do not attempt to repair accessories and options inside interlocked areas of the system while operating. Repair should be performed only by individuals who are qualified in servicing computer equipment and trained to deal with products capable of producing hazardous energy levels. 24 Chapter 9 Electrical and mechanical safety
