Case Studies

The following case studies illustrate the types of relationships we can build with clients and the way we serve many of them.

Case Study #1:  IT/DATA/TELCO requirement

CHALLENGE:  A major international financial institution was faced with rebuilding their primary North American DATA/Communications center after losing their previous facility to a disaster.

H&H’s PRIMARY OBJECTIVE: Provide scalable, modular rack enclosure infrastructure for the new facility’s high density MDF & IDF fiber optic and copper backbone.  This had to be accomplished with allowing a minimum of cooling air to escape from the pressurized floor through the densely packed enclosure rows.

SECONDARY OBJECTIVE: Provide scalable, modular Open Frame solution for a high density fiber optic infrastructure that satisfied both large trunk runs and individual fiber strand connectivity.

SOLUTION: H&H’s enclosure solution included close cooperation between H&H’s engineering/design team and the Site Architect & Infrastructure Engineers to ensure the very important issue of maintaining cooling air pressure was appropriately addressed from the very beginning of the process.  Our solution included an additional plenum base designed to fit inside the 24” floor tile, while allowing for a larger depth enclosure to be used to accommodate the significant quantity of Category 6 cabling required by the application.  An additional important element was the use of a brush system in both the plenum & enclosure base to maintain cooling air in the pressurized floor, yet allow for a large quantity of Cat 6 cables to enter the enclosure from the very same floor.

The Open Frame solution provided a different opportunity for H&H engineering & design experience to be brought to bear.  The initial request for the Open Frame elements consisted of a very standard form factor.  In concert with the systems engineers on the ground, H&H was able to make major modifications to the Open Frame elements based upon changing circumstances to make that solution exactly what the requirement had become.  We were able to add specific troughs and fiber drapes to assist the end-user in most efficiently routing the large quantity of fiber needed to make the many connections required by the application.


Case Study #2: Automated Test Equipment

CHALLENGE: A major Tier-1 Defense/Aerospace contractor was faced with replacing a sole-source vendor for a multi-bay ATE system that would not degrade functionality of the enclosure system, and would improve modularity while being cost conscious.

PRIMARY OBJECTIVE: Replace a no longer existing vendor, with no disruption to customer’s production capability, functionality or quality.

SECONDARY OBJECTIVE: Make the overall system more modular, efficient & cost effective.

SOLUTION: H&H engineers worked directly with contractor’s design group to completely redesign the system, while maintaining key elements that the contractor’s Production/Integration crews had come to expect.  H&H’s redesign was ultimately integrated into the contractor’s build-to-print drawing. Additional features were added to improve overall functionality of the multi-bay system, while significant manufacturing improvements were presented that simplified the process and showed considerable value-added return to both time in Production/Integration and budget.

Case Study #3: Networking Vendor

CHALLENGE: A major outsourcing Data Center/Network Systems vendor was searching for a simple way to enclose the patching centers that were used to monitor and control enclosure rows and individual enclosures within its multi-site remote Data Center topology.  H&H was presented with a broad requirement consisting of basic equipment types, and potential size and location restrictions.

PRIMARY OBJECTIVE: Design an acceptable form factor to house the patching system; allow significant cable access to the enclosure for patching; facilitate simplified use of the patching system; guarantee security within open Data Center environment; ensure compatibility with size restrictions inherent to Data Center space limitations.

SOLUTION: H&H Engineers provided a detailed 3D model, with full dimensions, to end user to determine feasibility.  After discussions over the model, and using the actual physical location parameters as a metric, a prototype was fabricated.  Prototype was proved out in application, is currently in quantity production, and in use in a number of customer’s Data Center locations.
