service providers or service partners) identifies that the repair can be accomplished by the use of a CSR part, HP will ship that part directly to you for replacement. There are two categories of CSR parts: • Mandatory—Parts for which customer self repair is mandatory. If you request HP to replace these parts, you will be charged for the travel and labor costs of this service. • Optional—Parts for which customer self repair is optional. These parts are also designed for customer self repair.
Recommended tools When replacing certain components, such as the power on/off module, the following tools may be necessary: • Torx T-10 and Torx T-15 screwdrivers • Phillips screwdriver Warnings and precautions Electrostatic discharge information To prevent damage to the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices.
Equipment symbols These symbols may be located on equipment in areas where hazardous conditions may exist. WARNING! Any enclosed surface or area of the equipment marked with these symbols indicates the presence of electrical shock hazards. Enclosed area contains no operator serviceable parts. To reduce the risk of injury from electrical shock hazards, do not open this enclosure. WARNING! Any RJ-45 receptacle marked with these symbols indicates a network interface connection.
WARNING! Verify that the AC power supply branch circuit that provides power to the rack is not overloaded. Overloading AC power to the rack power supply circuit increases the risk of personal injury, fire, or damage to the equipment. The total rack load should not exceed 80 percent of the branch circuit rating. Consult the electrical authority having jurisdiction over your facility wiring and installation requirements.
WARNING! To reduce the risk of personal injury or damage to the equipment, the installation of non-hot-pluggable components should be performed only by individuals who are qualified in servicing computer equipment, knowledgeable about the procedures and precautions, and trained to deal with products capable of producing hazardous energy levels. CAUTION: Before replacing a hot-pluggable component, ensure that steps have been taken to prevent loss of data.
