on a rack), cable tension reel/bracket, a server cable tray and a few other parts to neatly
manage the cables when the server is either extended or retracted.
UID LED and Switch – The Unit Identification LED can be used to indicate which ProLiant
DL360 server is being upgraded or serviced. A UID switch, either from the front or the
rear of the server, toggles both front and rear UID LEDs at the same time. The UID LEDs
are in blue for easy identification.
WOL – Wake on LAN permits remote restart of the server.
2 Power, Thermal, and Weight
Information
After the type and the number of servers have been determined, the next most important
parameters in deployment planning are on power, thermal and weight. This section enables
customers to calculate the necessary power, thermal and weight for the rack configurations
unique to their environment.
Effective planning begins with recognizing environmental and server basics such as the power
dedicated to each rack and how much power each server draws. After understanding these
requirements, the electrical power lines can be planned.
Section 2.1 lists individual weight, power rating and thermal dissipation specific to the ProLiant
DL360 server itself. The power consumption of the servers has direct relationship with the
thermal dissipation, which will determine the cooling system requirements as well as how the
ventilation system should be constructed around the racks.
Section 2.2 provides more tools to render input power budgets, and to derive input current and
thermal dissipation from the input power.
Following this, Section 2.3 outlines Compaq PDU choices best suited for building rack
configurations. This section describes technical specifications for two high voltage PDUs and one
low voltage PDU. It also distinguishes the outlet plug connector types and internal circuit
breakers associated with each PDU.
Section 2.4 bridges the server power ratings and the PDU power rating with a quick analysis and
guideline, for allocating the correct number and type of PDU for a particular rack deployment.
Lastly, Section 2.5 explores important requirements for weight capacity planning by summarizing
the weights of individual rack components and providing an example of how a typically
configured rack of 42 ProLiant DL360 servers can easily weigh as much as 1,700 lb
(771 kg)without the cables. Understanding the weight of a fully populated rack will enable the
server deployment planning, such as where to build the servers and where to populate the racks.
In addition, the floor support requirements can be derived from the weight information of all the
servers and other equipment installed in the racks.
Note: This Section 2 can be read selectively. Section 2.2.2 (Measured Input Power) and Section
2.2.3 (Input Power Budget De-rating) may be skipped, if full input power ratings will be used for
the power and thermal calculations, however these sections are highly recommended for
customers to gain insight into the configurations listed in Section 3 or planning a custom
configuration. The remainder of Section 2 should be understood for proper deployment planning
and installation.
