Installing PDUs
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 12 and Figure 13 . 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 13 .)
