UPOE, or Universal Power over Ethernet, is the latest innovation from Cisco with broad, positive implications for many enterprise operations. We are not new at this. Cisco has been pushing the standards since 2000 for the incorporation of electrical power running on the same cable as data.

UPOE is a big milestone as we can now consolidate 60 watts on a single CAT5E cable.   The flexibility that this enables cannot be overstated. Multiple third party vendors are jumping into the ecosystem here as dynamic environments using Virtual Desktops with integrated monitors, IP Turret systems for trading floors, not to mention building management, physical security and host of networking devices such as AP’s and compact switches that are often installed in very obscure locations.

The Catalyst 4500E is the initial beneficiary of this industry first for Cisco and this episode of TechWiseTV covers not just the use case and deployment examples as we go hands on with the big switch, but also a unique deep dive into understanding just how this works. A full appreciation for the engineering talent behind this innovation is warranted on this one when we go beyond the power negotiation and get into the physics of heat dissipation and other hurdles that had to be overcome. It’s the action packed TechWiseTV you have come to expect!

Double the Power: Industry’s First 60-Watt Power over Ethernet

July 18, 2011 at 8:50 am PST

If your customers are clamoring for a network with a smaller carbon footprint, one that’s more efficient, and more flexible, did you know the solution may be just an Ethernet cable away?

Today, Cisco is announcing the industry’s first 60-watt Power over Ethernet for the Cisco Catalyst 4500E. With Universal Power Over Ethernet (UPOE), you get twice the power per port than other switches – letting you power a greater range of devices through a single standard Ethernet cable. And, customers can use their existing network to power these devices.

What does the news mean for Cisco partners, customers, and the industry?

Rumors of the Cisco Catalyst switch’s demise have been greatly exaggerated

Greetings from Las Vegas!  I’m writing to you from Cisco Live at the Mandalay Bay Convention Center where we’ve unveiled an array of new products affirming that the rumors of the Cisco Catalyst switch’s demise have been greatly exaggerated.   While others in the industry were hard at work commoditizing the switching market, Cisco doubled down on innovation by revamping the entire Cisco Catalyst switching portfolio. 

Complete Catalyst refresh from the campus core to the network edge

Since 2010, Cisco has undertaken a top-to-bottom enhancement of the Cisco Catalyst switching portfolio starting with the introduction of the Catalyst Compact Switch, 2960-S, 3560-X, and 3750-X Series switches for fixed access; Supervisor 7-E and associated line cards for Catalyst 4500E; and now a revitalization of the flagship Catalyst 6500E Series product line consisting of, 

  • A 2 Terabit Supervisor that pushes the platform to new levels of performance and scalability with triple the switch fabric bandwidth and quadruple the scalability of the previous generation.
  • Six new line cards including the new 69xx Series that deliver 80 gigabit line rate, non-blocking performance as well as support for 40 gigabit Ethernet connectivity to handle future growth. 
  • An array of service modules – WiSM 2 for wireless, ASA-SM for security, NAM-3 for network management at 10G speeds, and ACE-30 for load balancing – tightly integrating network services to lower complexity and simplify operations.

Best of all, these new capabilities are available to the 25,000+ Catalyst 6500 customers without the need for a costly fork-lift upgrade!

Cisco Universal Power Over Ethernet – Universal, Resilient, Efficient

July 7, 2011 at 8:10 am PST

In the year 2000, we introduced 7 Watts inline power on our switching platforms. Since then, we have consistently doubled the power per port every 2 – 4 years. And now we are doing it again. Cisco Universal Power Over Ethernet (UPOE) is doubling the power delivered per port to 60 Watts on our modular access switching platform – the Cisco Catalyst 4500E. So what does that mean?

 It means network power resiliency to a wide range of devices and seamless integration with Cisco EnergyWise, to help lower energy bills.

Cisco UPOE opens up a whole new range of devices to network power that was previously not possible with PoE+: virtual desktop monitors, IP Turrets for financial trading, Personal TelePresence systems, compact switches, building management gateway devices, and more. Plus, it lowers capital expenditures by consolidating backup power infrastructure into the wiring closet. And with Cisco UPOE, you can forget the need for wall circuits for end devices that are connected to an access switch. Beyond capital expenditures, Cisco UPOE lowers on-going costs by eliminating battery replacement cycles for devices such as building badge readers.
