Installation Installing PDUs Choose PDU/PDRU locations with the following guidelines in mind: • Place PDU/PDRUs within the reach of power cords. • Place PDUs vertically whenever possible. See sample installations in Figure 43 and Figure 44. Installing PDUs horizontally can interfere with accessibility to units behind the PDU. (PDRUs must be installed vertically, as per the installation instructions.) • Place vertical PDU/PDRUs on each side of the cabinet so that the two power cords from the enclosure's redundant power supplies do not have to cross over replaceable components in the middle of the product. • Thirty-amp PDRUs must be installed directly behind the disk enclosure to achieve the highest densities in 2-meter racks. Hinged brackets allow HP's 30-amp PDRUs (HP E7681A and E7682A) to swing aside for servicing the disk enclosures (see Figure 44). Refer to the documentation supplied with the PDU/PDRU for installation instructions.
