You should also refer to the safety information documentation any time you do not clearly understand any safety information in the U.S. English publications. Replacement or additional copies of safety information documentation can be obtained by calling the IBM Hotline at 1-800-300-8751. - Page 8 Electrical voltage and current from power, telephone, and communication cables are hazardous. To avoid a shock hazard: v Connect power to this unit only with the IBM provided power cord. Do not use the IBM provided power cord for any other product.
- Page 9 Observe the following precautions when working on or around your IT rack system: v Heavy equipment–personal injury or equipment damage might result if mishandled. v Always lower the leveling pads on the rack cabinet. v Always install stabilizer brackets on the rack cabinet. v To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest devices in the bottom of the rack cabinet.
- Page 10 CAUTION: Removing components from the upper positions in the rack cabinet improves rack stability during relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a room or building: v Reduce the weight of the rack cabinet by removing equipment starting at the top of the rack cabinet.
