Power Efficiency Gains by Deploying 415 VAC Power Distribution
in North American Data Centers
This paper discusses various approaches to reducing power consumption and to increase end-to-end efficiency in the data center by bringing 415 VAC to the cabinet level. With power densities continuing to rise, more efficient solutions continue to be explored especially as power cost increases and power availability decreases.

Service capabilities for UPS
Uninterruptible Power Supplies, UPS
equipment is used to maintain service to
critical loads and improve uptime. Proper
maintenance of the UPS should provide the
owner with an Uninterrupted Revenue Stream,
lower capital expenditures and lower
long-term maintenance cost.

UPS TOPOLOGIES FOR LARGE CRITICAL POWER
SYSTEMS (>500 KVA)
With the increasing demand of
uninterrupted and high quality power for
critical loads, high power (>500KVA) UPS
systems are becoming more and more popular.
In order to properly design the critical
power system, the type of UPS and amount of
redundancy must be matched to the nature of
the load, the type of power distribution,
the quality of local power, and the required
reliability.

Balancing Scalability and Reliability in
the Critical Power system: When Does 'N + 1'
Become 'Too Many + 1'?
Uninterruptible Power Supply (UPS)
protection can be delivered through a
single-module approach or through redundant
systems. Redundancy enables higher
availability of critical systems and is
typically achieved through either an N + 1
or 1 + 1 design. While 1 + 1 systems deliver
a significant improvement in availability
over N + 1 systems and are regularly
specified for the most critical
applications, N + 1 remains a viable and
popular option for applications seeking to
balance cost, reliability and scalability.

Finding the Right Cooling and Power
Solutions for VoIP
As corporate America migrates to VoIP,
technical decision-makers face new
challenges, and new factors, in ensuring
continuity of voice services. In particular,
they need to reassess the systems currently
protecting IP network equipment from power
outages and fluctuations, and excessive
temperature.

Five Strategies for Cutting Data Center
Energy Costs Through Enhanced Cooling
Efficiency
As electricity prices and IT power
consumption continue to rise, IT-related
energy costs are getting increased scrutiny.
Cooling accounts for approximately 37
percent of electricity usage within a
well-designed data center and, in many
cases, represents a significant opportunity
to reduce IT energy costs.

Overview of The PoE Technology
Power over Ethernet (PoE) is an
evolving technology designed to deliver
power and transmit data on an Ethernet cable
at the same time. Modeling after the
technology used in telecommunication systems
which supplies power to telephones, PoE
powers network devices without the need of
AC electrical outlets. By eliminating the
power cords and the power infrastructure,
this technology greatly simplifies the
wiring and deployment matters and brings
lots of convenience and benefits in home,
office, and industrial environments.
