Benefits of Combining Ethernet Extenders with DMS Switches

By: Dennis Troxel | Posted in: ,

All network managers are familiar with Simple Network Management Protocol (SNMP), the ubiquitous network management system for Ethernet networks. But most are less familiar with Device Management Systems (DMS) a technology for managing the powered devices (PD) that are connected to Power-over-Ethernet plus (PoE+) switches.

In this blog post, we’ll walk you through three newly announced products from Transition Networks that allow you to manage your powered devices remotely (through the DMS), but also do it over extended lengths of  alternative cabling such as coax or two-wire unshielded twisted pair.

Smart Managed Switches with Unique DMS

When it comes to switches, there are many products available and most have pretty much the same functionality. However, Transition Networks recently launched a new feature in our Smart Managed PoE+ Switches, the innovative Device Management System (DMS). DMS is a technology that offers advanced tools for management of connected IP-based powered devices (PDs). No other company currently offers this solution, which is a very economical and highly beneficial alternative to a full-fledged video management system (VMS) system software package that can cost from $6,000 to $10,000.

The DMS capability is built into the switches and provides time-saving features enabling network administrators to establish and document a baseline deployment and automatically discover and remotely configure attached IP-addressable PDs. DMS also allows network administrators to monitor and automatically restart these devices using Transition Networks’ Auto Power Reset (APR), which is a huge value add.

Transition Networks DMS TopologyThe DMS provides a graphical topology, floor and Google Maps™ view of managed devices and allows network administrators to easily locate and keep track of devices while simplifying the troubleshooting of cable and IP connection issues. Network administrators are also able to monitor and analyze network traffic by day, week, port or device and perform health checks with thresholds.

While typical VMS software systems are often only affordable for larger businesses, the DMS offers access to similar functionality, visibility and management at a fraction of the cost for any size business.

Ethernet Extenders with PoE+

We’ve also just introduced a new Ethernet Over 2-Wire Extender With PoE+, which joins our Ethernet Over Coax Extender With PoE+ to round out our line of copper Ethernet extenders. (Transition Networks also offers copper-to-fiber media converters with PoE and PoE+ options, as well.) Both solutions reduce total cost and accelerate time to service by utilizing existing cabling infrastructure to upgrade or extend networks.

Our Ethernet Over 2-Wire Extender With PoE+ extends networks at near Gigabit speeds and provides power to security cameras, wireless access points, and other IP devices at distances beyond the typical 100m Ethernet cable limitation. The extenders are used in pairs, with a local (EO2PSE4052-111) and remote (EO2PD4052-111) unit installed at opposite ends of the 2-wire UTP cable. The extenders use Transition Networks’ proprietary safety extra low voltage (SELV) classification method to prevent power delivery to unintended devices for added safety.

Our Ethernet Over Coax Extender With PoE+ is also used in pairs, with a local (EOCPSE4020-110) and remote (EOCPD4020-110) unit placed at opposite ends of a 75-ohm coax cable to deliver data at near Gigabit speeds and a full 25.5 Watts of PoE+ power to edge devices. It also ensures safe power delivery through our proprietary SELV classification method.

Both types of extenders with PoE+ are the most flexible products on the market, accepting a standard CATx copper, single mode or multi-mode fiber Ethernet input. The Ethernet Over 2-Wire Extender also offers flexibility for data and power transfer over a single pair (2-wire terminal block) or multi-pair UTP (RJ-45) connection. Both solutions provide a user-friendly web GUI, which allows simple and secure access for configuration and management of both the local and remote devices through a single IP address. In addition, both feature Auto Power Reset (APR), which automatically reboots or recycles the connected end device in the event of a power interruption or failure, saving users even more time and money by eliminating the need to dispatch service technicians in order to handle simple power resets.

Ideal Applications

Combining the extenders with the DMS switch is ideal for a number of applications. One case might be situations where you need to upgrade or expand your security network. It is easier to extend the security network, power and monitor cameras in remote areas using the extenders, and you can keep track of multiple camera locations and monitor the power/traffic of those devices through the DMS.

Another use case could be in buildings where there may be existing coax from old IBM data networks or video conferencing equipment. That existing coax cable can be reutilized for point-of-sale equipment or other newer IP data applications. Telephony applications are another good example, where 2-wire cabling from older analog phone systems throughout a building or campus may be abandoned in favor of VoIP phones and can be re-used to connect those VoIP phones, PoE powered WAPs, or even sensors to allow older machinery to become part of the internet of things.

I’ve used Transition Networks’ products in my customer installations for years. I’ve always found their products, customer service, sales, and tech support to be top-notch. I wouldn’t even consider using another brand.
