Power-over-Ethernet (PoE) advances shown at Interop Las Vegas 2011

Microsemi recently demonstrated PoE innovations that improve power delivery, management and efficiency.


Microsemi Corp. demonstrated a number of Power Over Ethernet (PoE) advances at Interop Las Vegas 2011, including its recently announced Energy-Efficient PoE (EEPoE) front-end Powered Device (PD) ICs, and upgraded software that enables its PowerDsine midspans to seamlessly support the Internet's move from IPv4 to IPv6 technology for improved Internet addressing.

Microsemi demonstrations included:

  • Higher Power with Improved Efficiency: Microsemi's recently announced PD70x0x family of front-end Powered Device (PD) ICs enables PDs to receive up to 51 watts of power, with unparalleled energy efficiency at both full load and on standby.
  • Solutions for Migrating Network Power Infrastructure to IPv6 Technology: Microsemi PowerView Pro software upgrade, which provides a seamless, transparent solution for ensuring that Microsemi's PowerDsine midspans can support the Internet's next-generation addressing technology.
  • Support for Emerging HDBaseT Standard: Microsemi's recently announced PD6910x Power Sourcing Equipment (PSE) PoE manager ICs are the first to comply with specifications for HDBaseT, an emerging connectivity technology for long-distance transmission of uncompressed high-definition video, audio and power. Microsemi heads the sub-committee that is developing Power-over-HDBaseT (PoH) specifications which are expected to enable the delivery of 95 watts/port while being backwards compatible with IEEE802.3at-2009 and without infringing any of the PoE safety requirements.
  • Advanced Switching Applications: Marvell has integrated Microsemi PD69100 microcontroller capabilities into its Integrated Secure-Switch-Router (ISSR) platform. Microsemi's unique Distributed PoE architecture enables PoE controller functionality to be embedded inside Marvell's processors, increasing the level of PoE integration, performance and responsiveness for Marvell's ISSR solutions.
  • Expanded Evaluation Solutions: Evaluation boards for its PD70x0x and PD69108 solutions, as well as its PD69104A Auto-Mode PoE PSE manager IC, an integrated and energy efficient 4-port PoE solution.
  • Resilient Power Management: Resilient Power Management technology that alerts IT managers and prevents powered device disconnections.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
