2-4 Compaq ProLiant ML330e/ML330 Server Maintenance and Service Guide Preparation Procedures WARNING: Only authorized technicians trained by Compaq should attempt to repair this equipment. Because of the complexity of the individual boards and subassemblies, no one should attempt to make repairs at the component level or to make modifications to any printed wiring board. Improper repairs can create a safety hazard. CAUTION: Electrostatic discharge (ESD) can damage electronic components. Be sure that you are properly grounded (earthed) before beginning any installation procedure. See "Electrostatic Discharge Information" earlier in this chapter for more information. Powering Down the Server Before beginning any removal and replacement procedure: 1. Open the drive bay door on the front bezel. 2. Power down the ProLiant ML330e/ML330 server by pressing the power button on the front of the server. IMPORTANT: To completely remove all power from the ProLiant ML330e/ML330 server, you must disconnect the power cord. The front panel power button may not completely shut down power to the server. 3. Disconnect and remove the AC power cord from the AC outlet, and then from the ProLiant ML330e/ML330 server. 4. Disconnect any other external equipment connections to the server. Server Warnings and Precautions WARNING: To reduce the risk of injury from electric shock, disconnect all power cords to completely remove power from the system. WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system components to cool before touching them. CAUTION: Protect the server from power fluctuations and temporary interruptions with a regulating uninterruptible power supply (UPS). This device protects the hardware from damage caused by power surges and voltage spikes, and keeps the system in operation during a power failure. CAUTION: The ProLiant ML330e/ML330 server must always be operated with system unit covers on. Proper cooling is not achieved when the system unit covers are removed.
