Determining your power requirements

Your server can have power requirements different from a PC (such as, different voltage and different plugs). IBM® supplies power cords with an attached plug that corresponds to the power outlet most commonly used in the country or region to which the product is being shipped. You, the customer, must supply the proper power outlets.

1. Plan for system electrical service. For information on power requirements for a specific model, refer to the electrical section in the server specifications for that particular server. For information on power requirements for expansion units or peripherals, select the appropriate device from the list of compatible hardware specifications . For equipment not listed, check your equipment documentation (owner's manuals) for specifications.

2. Determine your server's plug and receptacle type so you can have the proper outlets installed. Tip: Print a copy of your plug and receptacle table and give it to your electrician. The table contains information needed for installing outlets.

3. Write down power information in your Server Information Form 3A. Include:
   • Plug type
   • Input voltage
   • Power cord length (optional)

4. Plan for power outages. Consider purchasing an uninterruptible power supply to protect your system against power fluctuations and outages. If your company owns a uninterruptible power supply, involve your uninterruptible power supply vendor with any type of uninterruptible power supply modification.

5. Plan an emergency power-off switch. As a safety precaution, you should provide some method for disconnecting power to all equipment in your server area. Put emergency power-off switches in locations readily accessible to your systems operator and at designated exits from the room.

6. Ground your system. Electrical grounding is important both for safety and correct operation. Your electrician should follow your national and local electrical codes when installing the electrical wiring, outlets, and power panels. These codes take precedence over any other recommendations.

7. Contact an electrician. Contact a qualified electrician to take care of your server power requirements and install needed power outlets. Give the electrician a copy of your power information. You can print the recommended power distribution wiring diagram as a reference for your electrician.
