    Note: In this document, derating the input power budget means not using the maximum rated input power values for the power supply. HP strongly recommends using the installation planner to ensure that the derated power budget will satisfy all the installation requirements, including future upgrade plans.
  • Page 11 HP ProLiant DL380 Generation 3 Server High-Density Deployment Table 4 demonstrates how calculating the derated input power of the system can significantly reduce input current and thermal dissipation. Table 4. Derated Current and Thermal Dissipation for Reduced input Power Assumptions...

    Modular PDU kit. Additionally, HP offers the Dual Input PDU, a fault-tolerant solution that automatically switches to a secondary input source when the first source fails. Equipped with two input ends and a built-in AC transfer switch, this device is designed for mission critical environments where customers depend on the reliability of redundant power systems housed in their facility.
  • Page 16 HP PDUs support both high-voltage and low-voltage applications. The input current rating for a ProLiant DL380 Generation 3 server is either 2.3 A at 240 volts or 4.9 A at 115 volts. To determine the number of servers supported by a PDU, divide the current rating of the PDU by the total input current rating of the server.

  • Page 17: Selecting Server Power Cords

    HP ProLiant DL380 Generation 3 Server High-Density Deployment Non-Redundant The following examples illustrate how to calculate the number of servers per PDU when using non- Power redundant power. Example One high-voltage PDU has a current rating of 24 A. The server has a total input current rating of 2.3 A at 200 volts.
  • Page 18 The power cord included with the North American model of the server can be used for low-voltage applications. Use a 1.8-m (6-ft) to 2.4-m (8-ft) long power cord with the standard rack rails and cable management arm.
