Preparation Procedures

Before beginning any removal and replacement procedure:
1. Open the drive bay door on the front bezel.
2. Power down the ProLiant ML330 by pressing the power button on the front of the server.
IMPORTANT: To completely remove all power from the ProLiant ML330, you must disconnect the power
cord. The front panel power button may not completely shutdown power to the server.
3. Disconnect and remove the AC power cord from the AC outlet, and then from the
ProLiant ML330.
4. Disconnect any other external equipment connections to the server.

Server Warnings and Precautions

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 can damage electronic components. Be sure you are
properly grounded (earthed) before beginning any installation procedure. See "Electrostatic
Discharge Information" earlier in this chapter for more information.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
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 server must always be operated with system unit covers on. Proper cooling is
not achieved when the system unit covers are removed.
