36 CONVERGED INFRASTRUCTURE An IoT enabler Keith Stewart, Marketing Manager, Networks Centre www.networkscentre.com One of the most potent technologies for converged infrastructure is Power over Ethernet PoE has made great strides in recent years, evolving from little more than a novelty when first introduced in 1999. Since then as Voice over IP (VoIP) phones became the norm, PoE evolved as a reliable companion technology. Using structured cabling to deliver both data and power makes so much sense, and so we’ve seen a twin pronged evolution of both IP devices and PoE combining to deliver a converged infrastructure. It’s worth reminding ourselves about the advantages that PoE brings. The most important is the elimination of mains AC voltage electrical cables and associated infrastructure, so less cables using a safer, low DC voltage. This in turn can simplify the powered device, potentially eliminating the need for transformers or inverters. System reliability is also improved, particularly as most critical IT systems have UPS back up, providing some protection against power outages that a mains powered device may not have. PoE also provides a distinct advantage when it comes to powering devices in remote locations that either have no local power supply or are difficult to access. This is particularly advantageous for IP cameras or light fittings for example. Centralised power supplies are inevitably more efficient than multiple distributed supplies, consequently the technology can help organisations reduce energy use and contribute to green initiatives. www.networkseuropemagazine.com
