Why Authentication Matters Like a passport or a driver’s license, an SSL Certificate or SSH Key is issued by a trusted source, known as the Certificate Authority (CA). Many CA’s will verify the domain name and the existence of your ownership of the domain name, by issuing digital certificates that contain a public key and the identity of the owner. This certificate is also an attestation by the CA that the public key contained in the certificate belongs to the person, organization, server or other entity noted in the certificate.
HTTPS stands for Hypertext Transfer Protocol Secure. It is server software which provides the ability to “secure” transactions that take place on the World Wide Web (www). If a website is running off a HTTPS server you can type in HTTPS instead of HTTP in the URL section of your browser to enter into the “secured mode”. HTTPS is often offered by financial institutions to support their online banking offerings in order to verify that the information being passed between your PC and their server is “secure”.

Transition Networks OAM/IP display at the SuperComm 2009 show in Chicago was designed to show the multiple levels of remote management available to service providers with Transition Networks products. The display showed products with basic remote monitoring features feature like: Link Pass Through and Far End Fault, to our most advanced remote management features such as: 802.1ag and Y.1731. The display had chassis based products, switches and stand-alone Network Interface Devices to showcase the wide range of products and capabilities available when using Transition Networks OAM/IP products.

Industrial Ethernet is a plant process and control specific technology, which is focused on the production techniques that are used to help make a company profitable through their manufacturing process. Over the last couple of years, Ethernet seems to have gained momentum over other limiting proprietary protocols. Industrial Ethernet environments often involve many types of unknown, hazardous environments and factors that can strongly influence the overall operation of standard Ethernet devices. In fact, Industrial Ethernet supports many crucial factors that are used when a loss of control does occur. The result could potentially cause serious disasters or even in some extreme cases, the loss of life, property or serious financial damage. In hazardous environments like oil, gas and chemical production, this can be especially true. A single issue can cost upwards of $1 million dollars a day at some companies, so it’s easy to understand why Industrial Ethernet has a more demanding focus on the potential for component failures, reliability and other problems that will need to be resolved quickly before serious loss occurs.

Recently, I came across an interesting application, and I realized an indirect way of using a feature common to all of Transition Networks managed Industrial Ethernet switches. I am referring to the Fault Alarm Output.
The Fault Alarm Output
All of Transition Networks’ managed industrial Ethernet switches incorporate a Fault Relay Alarm Output. This provides a hardwired mechanism for warning when power or one/any of the Ethernet ports loses its link status. In a commercial or office-grade piece of equipment this function is typically not needed: a downed network connection will pretty quickly be communicated to the IT personnel by humans; but in an industrial environment this may not occur. The installation could be remote, say at a well-head, or pump house. If the network fails an operation may be interrupted or cease, resulting in equipment damage, underutilized resources, or loss of revenue. A signal from the equipment could be tied to a local alarm system, or even a device that could communicate the alarm remotely. This is the intended use of the Fault Alarm Output.
