Customer Case Study
Improving Telecommunications Density and Efficiency
Less Energy, Less Real Estate, More Bandwidth
The need to meet subscriber demand for sophisticated multimedia services and support a converging IP network while still reducing their cost per bit led this European
operator to seek out an expert infrastructure solution that would increase their central
office datacenter and core site density by 150%, power and cooling capacity by 100%,
and efficiency by more than 20%. The client wanted a formula that could be implemented and verified once, then replicated to rapidly consolidate their numerous
regional data centers.
Specific requirements were:
n Keep the site live without any service interruptions throughout implementation
n Design a solution to that could enable the operator to cut the number of their
data centers by 50%, without footprint expansion at the remaining sites

Over 20 years
THE NEED
In order to meet subscriber demand for
multimedia technologies, this service provider
needed 2X the power and cooling capacity of
their regional data centers in the same footprint.
THE SOLUTION
Emerson Network Power implemented IT and
power distribution racks, chilled water cooling
system with in-line cooling, and highly efficient
DC power systems with remote monitoring to
increase the power and cooling capacity of the
site, improve overall site efficiency and meet
the client’s demand for zero downtime.
THE BENEFIT
n Strategically reorganized layout for growth
n 150% density increase
n 27% PUE improvement
n Replicable model for other sites
n >100% power & cooling capacity
improvement
n 26% reduction in OpEx*
n 20% reduction in needed CapEx*
KEY COMPONENTS
nKnürr ® IT and power distribution racks
nLiebert® chilled water cooling system
n AC and DC battery backup systems

n Improve site PUE and density
n Increase power and cooling capacity from ~400W/m2 to 1000W/m2 average and
up to 2000W/m2 in dedicated high density sections
n Enhance equipment layout to minimize hot spot issues and conflicting air flows
n Redesign existing site layout to accommodate future network equipment
n Improve energy efficiency to reduce CO2 emissions and operating costs
A Holistic Approach to Improving Site Efficiency
Emerson Network Power determined that a holistic approach was required to achieve
the customer’s objectives. The operator needed to simplify the layout of their equipment while improving the integration of their DC and AC power systems, cooling and
battery backup, and leverage metering and remote monitoring as well.
A comprehensive site audit by Emerson Network Power’s team of expert engineers laid
the foundation for discussions and the ultimate execution plan. The telecom/ICT
equipment would be separated into high/low heat density zones to accommodate cold
aisle containment and the ICT rack infrastructure. The DC and AC power plants would
be upgraded to increase redundancy and moved to a dedicated power and battery
room, improving efficiency and allowing for future growth. Real time monitoring and
reporting were also identified as critical to long-term site health and optimization. The
operating company agreed and plan execution began.
Emerson Network Power rapidly assembled the project team to perform detailed site
assessments, design work and assist the customer with proper equipment selection.
The final package included:
nNetPerform™ site assessment and design engineering services
n Knürr Miracel® IT server racks with integrated Liebert® MPX A+B
monitored and controlled power distribution units
nLiebert® HPC and HPM chilled water cooling system
with >1MW capacity, n+1 redundancy, free cooling
operation, smart aisle control/regulation, high
performance room cooling units with EC fans
n In-the-aisle Liebert® CRV cooling units and intelligent
iCOM control loop for smart inter working of system

Moving forward, Emerson Network Power can easily perform advanced tuning and optimization services
as well as ongoing site maintenance and support to this customer.
High Density Site Solution
By implementing the recommended high density solution, all targeted KPIs were met by the operator:
elimination of hot spots, increased energy efficiency, reduction of floor space, and flexibility for future
expansion and consolidation of sites. In addition, the capital expenditure required to fulfill future expansion
was reduced by over 20% compared to the customer’s expected, traditional technologies.

*Compared to fulfilling network demands using existing site and technologies.
Emerson Network Power was able to improve overall site efficiency by 27%. Without disrupting service to
subscribers, the power and cooling capacity of the data center was nearly tripled. Floor space was strategically reorganized to accommodate future network equipment and growth. Finally, the site has provided a
blueprint for achieving the customer’s goal of 50% reduction in number of sites across their network.
