Precautions for Portable Computer Products

Object entry

In addition to the general precautions described earlier in this section, 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.

◆Monitor Support Cover Do not place a monitor with an unstable base or a monitor heavier than 55 pounds (25 kilograms) on top of a monitor support cover. Instead, place the monitor on a work surface next to the docking base.

	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 in this section, 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 enclosures and safety interlocks. Many Compaq servers are interlocked so that the power supply is disabled 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 repair accessories and options inside enclosed or interlocked areas of the system. 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.
