Creating a Robust Information Transport
System

• Design the physical plant to become
a foundation that will optimize
network performance

• Standards organizations provide
valuable guidelines

– TIA/EIA 568, 569, 942, and others
– ISO/IEC

BICSI ITS Standards

• BICSI standards continue to
addresses increasing network
demands and application specific
requirements.

The OSI Model

• The OSI model specifies seven layers to
consider when designing your network.

The OSI Model

• The bottom layer of this model is Layer One –
the physical layer, which is the structured
cabling itself, but what Layer One does not
include is the physical support, or the
infrastructure, for the cabling.

A New Look at the OSI Model

• Legrand/Ortronics introduces Layer Zero –
The Infrastructure Layer ™, as a new
foundation for the OSI model to address the
critical role that infrastructure plays in network
performance.

Layer Zero™

• Layer Zero™ Physical Infrastructure Solutions
– Maximize Network Performance
– Enable Easier Moves/Adds/Changes
– Provide Scalable Solutions
– Promote Implementation of Physical
Support Best Practices
– Increase Cooling Efficiency
– Reduce Power Consumption

Layer Zero™

• A well designed Layer Zero™ infrastructure
– Maximizes network performance by
minimizing signal loss due to improper cable
support or patch cord routing
– Enables MAC work to have minimal impact
through the use of a strong physical support
foundation
– Assures flexible and scalable physical
support design that will support technology
demands from high frequency transmission
on the physical layer

Advanced Cable Management

• Well-designed physical support foundation
simplifies system maintenance and
extends the useful life of the system and
advanced cable management solutions
maximize system performance

• Vertical manager with switch port
protection

– Prevent stress and damage to the
switch ports even when the vertical
manager is loaded to full capacity

• Bend limiting copper and fiber cords

– Designed to protect cabling, eliminating
kinks and providing the proper bend
radius for fiber jumpers

Maximize Network Performance with
Effective Cable Routing at the Rack

Incorrect Correct

Maximize Network Performance with
Effective Cable Routing at the Rack

• Protecting the network means
safeguarding the switch ports in
addition to the copper and fiber cords

• Estimated cost per copper switch port
is more than $400*

* Cisco Nexus 5000 Unified Fabric TCO Calculator

Cable Pathways

• Cable management considerations impact
total cost of ownership

• Best practice - use bend limiter support
whenever cable exits pathway or makes
transition between two pathways

• Cablofil’s basket tray’s mesh construction
enhances airflow, a critical component in data
center environments

• Properly installed metallic tray also absorbs
electro-magnetic noise, enhancing network
performance

Work Area Cable Routing

Supporting Multimedia

• Existing buildings are often multi-
story structures with limited
pathway access

• Poke-thru fittings and raceway have
been the most effective solution but
may limit capacity if not properly
designed

• Patch cord routing must be a design
consideration

• Thermal Management
– maintain cold-aisle/hot aisle airflow,
regardless if the network equipment is front-
to-back, bottom or side venting

• Innovative Design
– Side rails and baffles redirect airflow to
maintain hot-aisle cold-aisle integrity
– Cable management options improves airflow
inside the server rack and/or cabinet

Total Cost of Ownership

• Data center managers can save 4 percent in energy
costs for every degree of upward change in the
ambient temperature, according to Mark Monroe, the
Director of Sustainable Computing at Sun
Microsystems

• To achieve the same exhaust temperature, in this
case 83°F, the typical EIA rack solution, needs intake
air at 40°F, where the solution using baffles to
manage passive airflow needs intake air at 55°F

• 55°F - 40°F= 15°F, therefore 15°F X 4% = 60%
reduction in energy costs for cooling

Summary

• A well designed physical support infrastructure

– Maximizes network performance by minimizing signal loss
due to improper cable support or patch cord routing

ƒ 3db loss in signal strength represents approximately 50%
loss in signal power

– Enables MAC work to have minimal impact through the use
of a strong physical support foundation

ƒ Protecting the network means safeguarding the switch ports
in addition to the copper and fiber cords

– Assures flexible and scalable physical support design that
will support technology demands from high frequency
transmission on the physical layer

ƒ “The goal of a pathway component is to accommodate all
standards-compliant cabling and the potential need for
change during the life cycle of the cabling system and
building.” *BICSI TDMM 12th Edition

Summary

• A well designed physical support
infrastructure….

– Promotes implementation of best practices and standards
compliance in critical environments like data centers

ƒ Provides maximum utilization of server cabinets by enabling
patching outside of the cabinet

– Increases cooling efficiency in the data center through
proper airflow management, cooling network equipment
more efficiently

ƒ Data center managers can save 4 percent in energy costs for
every degree of upward change in the ambient temperature,
according to Mark Monroe, the Director of Sustainable
Computing at Sun Microsystems

– Reduces data center power consumption with efficient
passive cooling design within racks, cabinets and
cable management areas

ƒ Based on the temperature analysis, Layer Zero™ passive
airflow baffles can lower a customer’s energy bill for cooling
by 60% when compared to a EIA comparable solution
