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.)
