34 Installation

Installing PDU/PDRUs

The 19-inch PDUs and PDRUs can be installed vertically or horizontally in the

rack. Choose PDU/PDRU locations with the following guidelines in mind:

■ Place PDU/PDRUs within the reach of disk system cords.

■ Place PDU/PDRUs vertically whenever possible. See sample installations in

Figure 10 and Figure 11. Installing PDU/PDRUs horizontally interferes with

the ability to service disk systems that are behind the PDU/PDRU.

■ Place vertical PDU/PDRUs on each side of the disk system so that the cord

from either power supply does not cross over replaceable components in the

middle of the product.

■ To achieve maximum density in 2-meter racks, install 30-amp PDRUs on

hinged brackets directly behind disk systems. Hinges allow the PDRU (HP

E7681A and E7682A) to swing aside for servicing obscured components.

(See Figure 11.)
