Ethernet Alliance study finds Power over Ethernet issues

By Michael Cooney, Networkworld

Reliability, connection issues, failure to deliver power traced to interoperability issues with Power over Ethernet. However bear in mind this study was done by the Ethernet Association to validate the need for PoE certification.

Four out five users experience challenges with power over Ethernet (PoE) deployments, according to a new survey of nearly 800 Ethernet designers, manufacturers, resellers, system integrators, network operators and others.

Conducted by the Ethernet Alliance in January, the study  found a number of key PoE insights, including:

  • Four out of five users experienced issues, including support, reliability, or connection challenges.
  • The top three PoE installations are cameras and phones, as well as computing and storage devices;
  • Of customers planning to implement PoE 63% said they would need 30w; 47% would need between 30-60w and 27% need greater than 60w.

The Alliance reported that while 78% of respondents experienced difficulties with PoE deployments, 72% expect improvement with products certified through the Ethernet Alliance’s PoE Certification Program. The study found 84% said they expect certified PoE devices would be more likely to work the first time, and 85% expect those devices to be more reliable.

“Lacking a registered trademark, the use of the term ‘PoE’ is not formally regulated, allowing any vendor to freely describe products and solutions as PoE-enabled. Additionally, terminologies such as ‘PoE+’, as well as non-standard PoE implementations are causing confusion with device interoperability among technicians, designers, and end users,” the Alliance stated.
