The ProLiant DL560 server requires just two 550-Watt hot-plug power supplies to run a fully loaded
and redundant system. It has the lowest power requirements of any major server in its class. One
power supply ships standard with 1P server models, but an optional Redundant Hot-Plug Power
Supply Option Kit is available. Two power supplies ship standard on 2P models. The server uses a
standard C14 power cord.
With its limited memory footprint and drive capacity, the ProLiant DL560 server can deliver enterprise-
class performance with a relatively low thermal load. The server has an innovative mechanical design
that provides excellent cooling and ventilation that dissipate generated heat out of the chassis quickly.
The design features redundant cooling zones across major server subsystems (memory, I/O,
processor) that provide 7x24 cooling. Each zone is independent of the others and is able to support
n+1 redundancy. Because no preheated air circulates toward the processors, the fans can cool
efficiently while spinning much slower than in many other servers.
HP engineers chose one fan design for use throughout the ProLiant DL560 server. The 1P models
come standard with five of these fans; the 2P models come standard with ten fans. Each fan in the
system is hot-pluggable and individually removable. The system can run fully loaded with five fans.
The zone cooling configuration enables the server to withstand up to three fan failures, if those
failures are not all within the same zone.

HP designed the dense ProLiant DL560 server to overcome challenges associated with deploying a
high concentration of servers in a single rack. The server ships standard with tool-free, snap-in sliding
rails with a depth adjustment range of 24 to 36 inches and a cable management system. This solution
provides good access to the rear cabling connections (Figure 8). Moreover, it allows the server to be
extended fully from the rack and temporarily locked in place for servicing, without removing the
cables from the server.

For added flexibility, the server design supports deployment in rack cabinets with round holes: The
Round-Hole Rack Rail kit includes variable-length rack rails compatible with 610-mm (21-inch) to
740-mm (29.13-inch) round holes. ProLiant DL560 servers can be deployed in two-post Telco racks
with the use of the HP DL380 G3 Telco Rack Kit. For details about deployment in Telco racks, visit

HP 9000 and 10000 Series Racks provide enhanced airflow for maximum cooling, so that they can
be fully loaded with servers using the latest and fastest processors. Blanking panels should always be
installed in any empty rack U-spaces to ensure proper airflow. Installing servers with processors
running at speeds of 550 MHz or greater in legacy Compaq 7000 Series Racks requires installation
