For years, industrial control systems have been characterized by proprietary devices, protocols, communications, and applications. However, at the Hannover Fair last spring, virtually every exhibitor showed products that support IP, Ethernet, or Wi-Fi interfaces—something that would have been unthinkable just a decade ago.
The Internet of Everything (IoE) is driving this change, with an exponentially growing number of connections among people, process, data, and things. The Internet of Things (IoT) is a key enabler of this evolution. By 2020, according to Cisco’s analysis, there will be 50 billion connected devices—all needing a common way to work together.
As I discussed in my last blog, the worlds of Information technology (IT) and operational technology (OT) are converging—and they are converging around standards. The good news is that the industry is recognizing that a fragmented, proprietary model does not scale, and inhibits the value of IoT deployments. The IoT standardization efforts are focused on four different areas: Read More »

Bringing Alien Worlds Together in the Internet of Things
In the 1990s, I, like millions of others, read the book Women Are from Venus, Men Are from Mars. This best-seller suggested that the frequent misunderstandings between genders make it seem as though men and women are from different, alien worlds. But it’s not just men and women who appear to be from different planets. Today, every organization that has begun an Internet of Things (IoT) deployment is bumping up against a fundamental disconnect between information technology (IT) and operational technology (OT). In many cases, these two groups are alien to one another—with separate technology stacks, network architectures, protocols, standards, governance models, and organizations.
In the first wave of the Internet, data and technology systems fell solidly in the realm of IT. IT systems focused on the flow of data across an organization, and with a few exceptions, did not get involved in production and logistics environments.
However, in many companies, a parallel organization—commonly called operational technology —has grown up to monitor and control devices and processes that act in real time on physical operational systems, such as assembly lines, electricity distribution networks, oil production facilities, and a host of others.

February is here. Winter is in full swing on this side of the equator. Summer is grasping the other. I know it’s been a warm one so far for our friends in Australia. But snowfall amounts in the Northeast has our ski areas in Northern California and the Rockies so envious. Such is Mother Nature right?
Recently, our team announced some important details for our Switching and Wireless products.
I thought I would take the time to let you all know more on these announcements.
First up, Nasser Tarazi, Wireless Product Manager, announced two new models. We will cover the new WAP351 this week and the new WAP131 next week.
The New Cisco WAP351
The new Cisco WAP351 perfect for conference rooms, classrooms, hospitality and other flexible deployments. It offers Dual Radio (2.4Ghz and 5Ghz) wireless N connectivity, a 5-port Switch with PoE PD and PSE support, Single Point Setup, Captive Portal and comes with Limited Lifetime Warranty.
The WAP351 offers something new to the Wireless portfolio. Here is a quick Power Over Ethernet (PoE) primer. PoE Powered-Device (PD) is the ability to power the device through an PD-capable Ethernet port. PoE PSE (Power Sourcing Equipment) is the ability to supply power a device connected to a PSE-capable Ethernet port. In terms of power, a standard PoE port can support a maximum output of 15W, while a PoE+ port supports up to 30W.
Now, back to the WAP351. As mentioned above, the WAP351 support both PD and PSE. This means if the WAP351 is connected to a PoE+ switch like the SG300-10PP, the WAP351 can be power through PD-capable Ethernet port, while at the same time powering a standard PoE device like a phone or another AP, like the WAP131 through the WAP351’s designated PSE-capable Ethernet port.
More on Wireless Access Points and PoE:
- PoE: Power over Ethernet. PoE enables Power and Data to be combined onto a single Ethernet cable to power devices such as access points, IP phones, or IP cameras
- PSE on a WAP is exclusive to the new WAP351
- A WAP with PSE is attractive for verticals such as education, hospitality, and smaller offices and meeting rooms where both wired and wired access is required
- PoE enables WAP’s or other endpoint devices to be installed where power typically is not available, such as on a wall or ceiling. This allows for greater flexibility during deployments.
- All Cisco Small Business WAP’s support PoE PD
- Dual-Radio WAPs requiring 802.3af PoE power = WAP131, WAP351, WAP561
- Dual-Radio WAPs requiring 802.3at PoE+ power = WAP371, WAP351 when using the PSE with full power budget
- The WAP351 can be powered by 48V/1.25A external DC power if a 802.3af/t PoE switch is not used or available
- The WAP351 can provide 6w of PSE when using 802.3af
Ok you got it? Make sense?
Cisco 300 Series Switches
In other news:
Switching Product Manager Michael Wynh announced several price reductions on the ever-popular 300 Series Switches. This is good news for our customers and channel partners alike. Businesses can maximize their budgets and take advantage of Cisco’s class-leading PoE switching products. For more information on these important updates, please contact your local Cisco Representative or check out our support community.
That is it for now. Thanks for hanging out with us.
Until next time,

Note: This blog was simultaneously published on the SNIA blog.
When I first started in storage technology (it doesn’t seem like that long ago, really!) the topic seemed like it was becoming rather stagnant. The only thing that seemed to be happening was that disks were getting bigger (more space) and the connections were getting faster (more speed).
More speed, more space; more space, more speed. Who doesn’t like that? After all, you can never have too much bandwidth, or too much disk space! Even so, it does get rather routine. It gets boring. It gets well, “what have you done for me lately?”
Then came Flash. Read More »

It is Friday the 13th and we have a full moon, perfect time to provide a quick update from the Cisco SMB Team.
First off, we have posted a Teaser Announcement providing a quick view of some new products that are coming out later this month. The entire Cisco SMB Team has been working hard on this new launch so look for more information that will be coming out.
220 Smart Plus Series
The Switching Team currently has a cisco.com for the new 220 Smart Plus Series.
Ivor Diedricks posted a new Blog earlier this month called Understanding the different types of Ethernet Switches. He explains the differences between fixed and modular switches, and goes into the details of what makes an Unmanaged, Smart and Fully Managed models. It is a good read, if you haven’t already, please take a look.
Finally, I have a new RV325 emulator on our Cisco Emulator Page. These emulators provide you the chance to take a test drive through our device user interface. You can take a look at our easy-to-use configuration wizards, configure features such as VLAN’s, Single-Point-Setup on our Wireless Access Points, and even configure VPN’s on the routers.
Make it a safe Friday the 13th!
