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.
