To prevent electrostatic damage: • Avoid hand contact by transporting and storing products in static-safe containers. • Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations. • Place parts on a grounded surface before removing them from their containers. • Avoid touching pins, leads, or circuitry. • Always be properly grounded when touching a static-sensitive component or assembly. Server warnings and cautions Before installing a server, be sure that you understand the following warnings and cautions. WARNING! To reduce the risk of electric shock or damage to the equipment: • Do not disable the power cord grounding plug. The grounding plug is an important safety feature. • Plug the power cord into a grounded electrical outlet that is easily accessible at all times. • Unplug the power cord from the power supply to disconnect power to the equipment. • Do not route the power cord where it can be walked on or pinched by items placed against it. Pay particular attention to the plug, electrical outlet, and the point where the cord extends from the server. WARNING! To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system components to cool before touching them. CAUTION: Do not operate the server for long periods with the access panel open or removed. Operating the server in this manner results in improper airflow and improper cooling that can lead to thermal damage. Preparation procedures To access some components and perform certain service procedures, you must perform one or more of the following procedures: • "Power down the server" (page 25) If you must remove a server from a rack or remove a non-hot-plug component from a server, first power down the server. • "Extending the server from the rack" (page 25) If you are performing service procedures in an HP, Compaq branded, telco, or third-party rack, you can use the locking feature of the rack rails to support the server and gain access to internal components. For more information about telco rack solutions, refer to the RackSolutions.com website (http://www.racksolutions.com/hp). • "Removing the server from the rack" (page 26) If the rack environment, cabling configuration, or server location in the rack creates awkward conditions, remove the server from the rack. • "Removing the access panel" (page 27) If you are servicing internal components, remove the access panel. 24 Removal and replacement procedures
