Data centres are complex and quirky puzzles for EMI shielding purposes. There are many constraints that call for out the box thinking and innovation. We at Brightsandz, made good of such a challenging assignment at one of India’s largest telecom operators. The target was to reduce radiation levels to below Occupational level exposures.
Anatomy of a complex EMI problem
We had to work around standard Panduit rack configuration which gave us very little space and keep the cooling coefficient high. This meant that we were working in highly compressed spaces and yet we had to account for movement of air draft. Balancing space, air movement along with EMI / EMC considerations along with people movement around the racks required us to think out of the box and innovate. So we did better. We retrofitted sandwich walled shields on the Panduit racks.
Innovate and Improvise
So we did better. We used retrofitting on the Panduit racks. By using a two wall box structure with sandwiched 2 core shield structure, we were able to find a solution that ticked all the boxes – ergonomics, aesthetics, functionality, air conditioning and staff movement. The client was super happy with the result. While the patent office did not merit us with a patent for the innovation – but this is the only functioning example of this find of a shielding approach. The client was double happy on another count – atleast 70% cost savings on any other shielding options which at that time had to be imported into the country.
This happens to be one of the most challenging and yet successful and satisfying shielding projects till date. We achieved what we set out to accomplish at a cost which was atleast a fourth or fifth of the solutions otherwise available.
