ADC Helps Stansell Electric Build Showcase Data Center
MAPCO values scalable and manageable network infrastructure
CASE STUDY
Introduction
Serving and satisfying customers is the number
one priority for MAPCO Express, a wholly owned
subsidiary of Delek US Holdings which operates
more than 500 convenience stores under the
MAPCO Express

brand names.
In each of the stores, convenience means
featuring the right mix of premium coffees,
snack and food items, and consumer products
that range from over the counter medicines
to automotive supplies. Yet making sure that
a visit to one of these stores is truly convenient
requires that products are easy to find and
neatly displayed.
Anticipating expansion in the number of stores
operated by the company, this same “ease of
use” commitment was a key driver in design of
the LAN and data center for the company’s new
headquarters building. In meetings with electrical
contractor Stansell Electric Company, MAPCO
executives expressed concern about managing
the network going forward. Pointing to the
existing cramped data center, a key requirement
for Stansell was to ensure that both the LAN

and data center would not only accommodate
routine changes but also easily scale for growth
at the headquarters building. As with the stores,
MAPCO wanted its corporate data center neat
and orderly so that any voice or data circuit in
the building could be easily identified.
At the same time, this project represented an
opportunity for Stansell Electric to showcase its
competence in low-voltage projects. Faced with
a tight construction schedule, Stansell sought a
partner that could provide a quality cabling and
connectivity solution, provide a competitive price,
and deliver a high level of service and engineering
support. More important, Stansell sought a
partner that would not miss commitments. As
Stansell reviewed its options, it chose to work
with ADC on the project. MAPCO executives
liked what they saw from ADC in early meetings
and added ADC to the construction team for this
important project.
“We try to put ourselves in our customer’s shoes,
as if this is our building and we intend to live
and do business here,” said Brad Johnson, data
communications account executive for Stansell
Electric. “We draw from our past experience and
make recommendations early on that MAPCO
may not have thought of until it was too late or
more expensive,” he said. “Our customers tend
to see us as partners and having ADC part of the
team only makes us better.”

Product Quality and
Commitment to Service
As with most design and installation projects,
change is the norm. For this project with an
unusually compressed schedule—where ceiling
grid on the second floor was installed before
doors on the first, for example—even the smallest
change could delay the project and increase
costs. ADC was selected based upon a reputation
for great service from everyone from the local
account manager to product managers at ADC
offices in Minnesota and Colorado.
With the tight schedule, Stansell also valued a
single source vendor for cable, panels, outlets and
modular jacks, not just for peace of mind that
the components work together, but also to make
sure products were available through distribution
when needed. ADC was also selected because
the company is one of the few manufacturers of
an end-to-end cable and connectivity solution.
Finally, Stansell intended the MAPCO project to
be a showcase for earning low voltage projects
from other clients. ADC was chosen because of
its reputation for quality, reliability and attention
to the details of cable management that is vital
for maintaining a neat, organized and easy-to-use
LAN and data center.
The new network for the MAPCO headquarters
building included roughly 600 drops across the
two-story building supported by one data center

with open relay racks segmented by voice and
data services. All passive network infrastructure
products from the data center to the work
areas were from the ADC portfolio of TrueNet

structured cabling solutions—TrueNet Category
5e for voice and TrueNet Category 6 for data,
each carrying a 20-year application assurance
warranty from a single manufacturer.

Angled Panels Enforce Order
Early in the design phase, MAPCO agreed to
the value of installing TrueNet Category 5e and
Category 6 angle left/angle right patch panels
for distribution fields used to patch users to
active voice and data equipment. These patented
patch panels allow each six-pack module of
RJ45 connectors to be angled to the left or to
the right so that patch cords naturally flow into
vertical cable managers. Used with ADC’s Glide
Cable vertical managers, the angled panels also
eliminated the need to pair horizontal cable
managers with each patch panel, allowing greater
rack density without sacrificing access to perform
adds and rearrangements. As a result, the relay
racks retain a neat and manageable appearance,
speed circuit identification, reduce errors and
improve availability of voice and data services
for all users.

The Stansell installation team takes great pride
in their craft. The combination of neatly dressed
IDC rear terminations and an orderly flow of
patch cords from the angled RJ45 modules into
vertical cable managers on the front resulted in
relay racks that meet the high expectations that
Stansell expects on every job. More important,
MAPCO loved the results.
Rear angled IDC terminations enforce orderly flow into vertical cable managers. Glide cable manager helps
increase rack density by eliminating need for pairing a horizontal cable manager with each patch panel.
Highly dense relay racks with angled patch panels leave plenty of room for technicians to safely make
changes and rearrangements and meet MAPCO requirements to keep the data center neat and manageable.

Space Saving Cable
Design for the two-story building called for one data center serving both floors. While this design
used less floor space and offered easier administration of the network from a central distribution frame
location, there was a limit on the number of three inch conduits installed between floors. Fortunately,
ADC cable featured an average outside diameter that is as much as 32% smaller than competing cable.
To achieve the dramatically smaller cable size, ADC utilizes AirES technology for its TrueNet riser and
plenum cable.

Compared to all insulation materials, air is the best material to resist breakdown when an electrical
field is applied. AirES combines traditional FEP with channels of air for individual conductor insulation.
As a result, TrueNet cable requires less insulation material and—with superior insulation—uses smaller
gauge copper, both of which contribute to smaller individual conductors and smaller outside diameter
of finished cable.
TrueNet cable manufactured with AirES technology used throughout the MAPCO facility exceeds
standards for both electrical performance and crush resistance. More important, the smaller outside
diameter cable allowed MAPCO to remain within standards for conduit fill ratios and still have room
for expansion without adding new vertical pathways.
Conclusion
For MAPCO, the project was on time and met expectations for ease of day-to-day management and for
growth of the operation. “We are clearly poised for growth without the impending mess that normally
happens when changes occur. The data center looks great today and will be functional as we grow,”
said Robin Perry, manager of technical infrastructure and security for MAPCO. “It is really great to have
our servers and routers permanently cabled (to patch panels) so that we only move and add patch cords
to make changes. This ensures that our data center will have that just-installed look for many years
to come,” said Perry, referring to the cross-connect distribution fields created by Stansell for handling
moves, adds and changes.
In the end, the project was a great success due in part to the level of support received from ADC,
according to Stansell Electric project manager Terry Catignani. Throughout the project, product was
always available immediately through distribution. When last minute changes occurred, such as an
additional relay rack and vertical cable managers, there was no delay in delivering product to the jobsite.
“Lack of surprise is a good thing,” said Catignani. “We had plenty of last minute changes and last
minute requests. These were never a problem because our (ADC) account manager is technically trained
and was always there for us. We got materials (through distribution) when we needed it, too,” he said.
Not surprisingly, testing revealed very low failure rates, which made turning the network over to MAPCO
easier to do, according to Catignani.
MAPCO is proud of the final product—proud enough to allow Stansell to show others the details of
creating a data center that remains functional due to attention to the details of cable management.
