NOTE Some local codes do not allow a 16-amp device to be connected to a 16-amp service. Consult a qualified electrician or local regulatory authority before beginning electrical site preparation. Cabling Preparation for the HP NetServer LPr Assess How Components Will Be Connected to the Server You may find the following steps to be helpful before you begin cabling: • Review the layout of the rack installation generated with HP's rack configuration tools. (See Step 2 in Chapter 1 for more information.) • Consider the cabling guidelines discussed in Chapter 3, in the section "Data Cabling Principles Used in Determining Rack Locations." Attach Cable Guide to Rack Column Using the instructions included with the Cable Guide hardware, attach the Cable Guide(s) to the rack column. Mount Power Distribution Units Plan the location of the Power Distribution Unit or Units (PDU) by reference to amperage, power, and the number of receptacles. For additional information on PDUs see Chapter 3, the section titled "Wide-Ranging PDU Configurations." The following subsections describe the types of PDU's and three ways to mount them: ◊ Horizontally on the rear columns of the rack. ◊ Vertically on the rear columns of the rack. ◊ Horizontally on extended rear brackets for the LPr. 15
