Eaton, a global leader in power management, is today proud to launch its first UL certifiednetwork card, the Gigabit Network M2.
This launch marks the expansion of Eaton’s cybersecurity program and collaboration with global safety science organization UL establishing measurable cybersecurity criteria for network-connected power management products and systems. New UL cybersecurity certification for Eaton’s connected uninterruptible power supply (UPS) technology demonstrates the company’s worldwide capabilities to meet stringent specifications and customer expectations for safe, secure power management in increasingly connected environments.
As Eaton’s latest Uninterruptible Power Supply (UPS) connectivity device, the Gigabit Network M2 empowers IT professionals with new capabilities and superior speed, while ensuring the highest level of defense against emerging cybersecurity threats and meeting the stringent UL 2900-2-2 security standard.
Development of the Gigabit Network M2 followed Eaton’s overarching “secure by design” philosophy, a deeply embedded approach that manages cybersecurity risks throughout the entire product lifecycle.
The Gigabit Network M2 improves power system reliability by warning administrators of issues and enabling the orderly, graceful shutdown of servers and storage. The device is also compatible with Eaton’s Intelligent Power Manager (IPM) software and optional second-generation monitoring probes, enabling it to improve business continuity and strengthen data center resilience. For instance, in the event of power or environmental anomalies, the Gigabit Network M2 can trigger policies configured to keep mission critical applications running.
Securing ubiquitous connectivity
In a world that’s becoming ever smarter and more connected, security and trust are top priorities. Nowhere is this truer than in the data center. As home to the most business-critical information and applications, these facilities make attractive targets for cybercriminals. As a result, organizations must work harder than ever to make their data centers as secure and resilient as possible.
While UPS systems have long been critical to ensuring data center continuity and disaster recovery, it’s now normal for them to have public cloud connectivity. This delivers benefits around network monitoring and optimization, improving overall reliability and enabling the UPS to be used for energy storage, or as part of a UPS-as-a-Reserve solution. Yet, greater UPS connectivity also offers a way into the data center and it’s an attack vector that cybercriminals have exploited in the past. A compromised UPS can endanger resilience, enable intelligence gathering on a site’s power consumption, or act as a launch pad for further network intrusions.
A powerful security solution
As cyberthreats become more prevalent and sophisticated, it’s vital to ensure the UPS doesn’t offer an entry point. Eaton’s secure development lifecycle ensures products are “secure by design”. The Gigabit Network M2 is engineered to protect data center UPS and power distribution units (PDUs) against cyberthreats throughout its lifetime. To accomplish this feat, Eaton closely collaborated with renowned standards leader, UL, as part of a global joint effort between its Power Quality Division (PQD) and Cybersecurity Center of Excellence(CSCE).
With the industry’s first test lab approved to participate in UL's Cybersecurity Assurance Program, and a second lab recently approved, Eaton can rigorously assess its products for compliance with both UL 2900-1 and 2900-2-2 standards.
The Gigabit Network M2 is now UL Certified to the UL 2900-2-2 standard. Its cybersecurity enhancements include stronger encryption, configurable password policies and the use of signed digital certificates. In addition, the device is compatible with today’s widespread Gigabit network switches and can be installed in Gigabit-only data center networks.
“After a lot of hard work, dedication and close cooperation between our teams worldwide, we’re thrilled that the Gigabit Network M2 has gained UL certification”, says Eric Rueda, Eaton’s software and connectivity product line manager, Power Quality Division, Electrical Sector EMEA. “This is an achievement that really demonstrates the power of combining the specialized expertise and resources across our business”.
“In a world of ubiquitous connectivity, trusted environments are crucial”, continues Eric Rueda. “Our customers don't want to take chances with their systems. That’s why cybersecurity is part of our DNA at Eaton. We see security as a continuous journey and our approach is designed to safeguard products across the entire product development lifecycle, so cybercriminals can’t get a foothold. With products tested in our specialized labs to UL’s stringent standards, we can ensure customers can connect their world with confidence”.
“As industries introduce more and smarter connected technologies that further interlink everyday life, trust is becoming increasingly important”, Rueda concludes. “We need to turn the Internet of Things into a safe Internet for Beings—and our collaborative efforts are helping to make that happen”.

Have you ever thought, "This crisp cold beer really reminds me of my uninterruptible power supply?" Well, the beer you drink and the UPS you use to power your data center are arguably of equal importance, and more of a science that one may think. Here are 9 ways the beer in your glass matches the UPS in your server room.
The battery system in a UPS represents the heart of the power protection benefit. This key element performs two functions: (1) it delivers energy during a power outage, and (2) it stores energy efficiently for extended periods of time. That stored energy is instantaneously available when needed to support the critical load on the UPS. In order to perform the above functions reliably, the charge level of the battery must be maintained. At the same time, battery charging should be controlled to maximize system efficiency and, more importantly, to maximize the float service life of the battery system.
Two types of battery charging schemes have traditionally been used for UPS battery systems. The older and more commonly known is the “float” charge, which involves applying a constant voltage charge to the battery continuously for purposes of maintaining full charge during day-to-day operation of the UPS. This works quite well in many conventional battery applications. However, battery life may not be optimal, due to overcharging, for batteries that are used very occasionally as in standby applications such as a UPS. In a UPS, the battery system may sit in float mode for many months, without ever experiencing a discharge. Float charging for long periods of time means that “trickle charge” energy is constantly forced into a battery which is effectively already full. This results in very gradual degradation of the lead plates (positive grid corrosion), and it can impact float service life.
Standby applications are better suited for “opportunistic” charging schemes. The system Eaton® utilizes is called ABM technology, which is essentially a set of charger controls and automated battery tests. It is implemented in Eaton single-phase UPSs from 500 VA to 18 kVA and three-phase models from 10 kVA to 3.3 MVA. Opportunistic charging schemes like ABM allow for periods of time where the battery is being fully charged, and periods of time when the charger is disabled. This reduces the time that the battery is subject to grid corrosion when compared to a traditional float charger — a reduction in grid corrosion that yields a measurable increase in battery life for UPS applications.
ABM Operational Summary
As shown graphically in figure 1, ABM consists of three operating modes:
The UPS enters the charge mode under any of the following conditions:
In charge mode, constant voltage charging of the batteries is used to recharge a discharged battery after a power outage, or whenever the ABM process is restarted. Charge voltage target is set to the manufacturers’ float level, and charge current is greater than 0.1 C A. Constant voltage charging lasts only as long as it takes to bring the battery system up to a predetermined float level (there is a 100-hour maximum time limit). Once this level is reached, the UPS battery charger remains in constant voltage mode, maintaining a float level. The current is at trickle charge levels during this time, and a 24-hour clock is started. At the end of 24 hours of float charging, the UPS automatically performs a battery test (see figure 1) at two different load levels to verify that the battery is performing, and to collect data for comparison to previous and subsequent automatic battery tests. If the test fails, an alarm is activated on the UPS and also through the remote monitoring system that may be connected to the UPS. At the end of the test, the charger resumes constant voltage mode and remains in that state for an additional 24 hours.
Rest mode begins at the end of charge mode; that is, after 48 hours of float charging, and after a successful battery test. In rest mode, the battery charger is completely turned off. The battery system receives no charge current during this mode, which lasts about 28 days. Then, the charge mode is repeated as described above. Since the battery clearly spends most of its time in rest mode, as a result, the following benefits are realized:
During rest mode, the open circuit battery voltage is monitored constantly, and battery charging is initiated if any of the following occur:
There are two other battery tests that are performed as a part of the ABM cycle. The first is meant to detect battery conditions which could lead to thermal runaway. The bulk charging period is timed and if the float voltage is not reached in a predetermined time, an alarm is triggered and the charger is shut down. The second test is performed after the charge cycle is completed (i.e., at the beginning of rest mode). The battery is discharged at about 15% load for up to 6 minutes, then at 50% load for 45 seconds.. Upon reaching this point, the battery voltage is measured. If the voltage is below a specified threshold, dependent on the load, then an alarm is signaled indicating the battery is nearing the end of its service life and should be replaced.
ABM may be disabled by the user or an Eaton field technician at any time. In this case, the UPS battery charger operates as a conventional float charger only. This is recommended when a wet cell or flooded electrolyte battery is used with the UPS. ABM is intended for use with VRLA batteries. As a result, wet batteries do not benefit from ABM controls.
Many observers express concern regarding the ability for the battery to maintain capacity if called upon to support the UPS near the end of its rest mode. In other words, how much battery capacity is available on day 27 of a 28-day rest mode? Using a 15-minute battery as an example, under this condition, the battery would provide all but about 30 seconds of its 15-minute backup time. This is proportionally true for other battery sizes, as well. The intent in selecting the 28 day rest period is to limit the loss of capacity to approximately 5%.
The ABM process above describes the benefits of using a “opportunistic” charging scheme. Those benefits, specifically extended service life, are in fact substantiated by data and empirical testing performed by Eaton as well as other independent sources. Some of this testing is recent and some of it was performed as many as 25 years ago.
ABM is not a new battery management feature. In fact, Eaton has been using ABM in its UPS products for 27 years, and it has proven itself beneficial in the field for more than two decades.
Note that in figure 4, the curve identified as “23/23 days” represents a float charger, and ABM (as implemented today) is best represented by the curve labeled “12/23 days.” At an ideal 25°C (77°F), there is a theoretical increase of six years in battery service life reflected in this analysis.
The above information shows a clear benefit of cyclic charging in UPS applications, both in simulated and in actual performance tests. These results would not be expected with non-VRLA batteries or in applications such as motive power chargers where the battery is discharged/recharged daily and therefore not deployed in a standby application.
ABM is unique in the UPS industry, but similar opportunistic designs are utilized by battery manufacturers and battery charger designers worldwide. The criticality and cost of the battery subsystem of any UPS dictates that special consideration be given to battery longevity. Additionally, with environmental concerns relating to battery removal and disposal becoming more prevalent, it is desirable to reduce the frequency of battery replacements during the life of the UPS electronics. ABM offers a significant benefit over conventional “battery monitors” which don’t provide charging control, and “multi-stage chargers” which protect the battery, but do not provide useful extension of battery service life.
Over the past 27 years, ABM has proven itself in both large and small UPS products, from the desktop to the data center, and from the medical lab to the factory floor. Anywhere a UPS is installed, a battery system is depended upon to provide backup power protection for critical business processes and even for personnel safety. The battery is all too often ignored as a maintenance-free product, not requiring attention or inspection. This neglect, though common, can be costly and possibly disastrous. The ABM system, by its nature, helps to provide early detection of problem batteries and thus protect the battery from unnecessary failures like electrolyte dry out and thermal runaway, while functioning to extend the useful life of this key component of power quality.
Before purchasing a server cabinet or server rack it is important to understand the difference between the different products that are available. This will ensure that you purchase exactly what you need.
Server Rack Cabinets such as the 42u Server Cabinet are generally nineteen inches wide by industry standards. This product is mostly used to install servers, UPS ES, monitors or similar equipment. Server rack cabinets, for the most part, are twenty four inches in width, and thirty six inches deep. Some companies offer other measurement options to meet customers’ needs, however. Server rack cabinets usually have a perforated front and rear. This feature offers ventilation for the equipment being housed. This is crucial to providing a safe environment for this type of equipment which generates a good deal of heat.
Network cabinets or Network Racks are often confused for server cabinets. However, there is a difference. Network cabinets are generally used for the storage of routers, patch panels, switches and a wide variety of networking equipment as well as networking accessories. In most cases a network cabinet will be far shallower than a server rack cabinet, generally measuring in at less than thirty one inches deep. Networking cabinets will sometimes have glass or a strong plastic front door. Network cabinets also generally do not have perforated enclosures. The type of equipment generally housed in network cabinets does not generate the same amount of heat as that housed inside a server rack.
Because one product can not fulfill the needs of all office equipment storage, it may become necessary to do a thorough evaluation of the type of equipment being used, or that will be used, in order to make the most informed purchasing decision. In many cases, office spaces will require the use of both a server rack and a networking cabinet in order to house the various equipment that will be used there.
It is important to note, that improperly housing heat generating equipment is dangerous. This could cause damage to your equipment, or worse could become a fire hazard due to the temperatures which some servers can generate. Good rack dealers will help you decide which product is best for you. Contact Brisk Worldwide to learn more!
Demands on data centers are increasing, while the space and budgets for these facilities stagnates. As data center staff are forced to be more efficient, they turn to metered power distribution units (PDUs). A metered PDU offers the ability to conserve resources – money, personnel hours and space – at a granular level, freeing up staff to concentrate on more strategic tasks.
Metered PDUs' resource-saving benefits
1. Reduce cooling costs.
The cost for regulating a data center’s temperature can eat up an operating budget. Modern hot-air containment solutions help to reduce costs, but the lower operating temperatures for legacy rackmount PDUs mean they can only help so much. Newer metered rack PDUs have a higher operating temperature – up to 140°F/60°C – meaning a big cut to the cooling cost of your facility.
2. Maximize space
Instead of requiring a dedicated infrastructure rack, a metered rack PDU is designed to utilize space that would otherwise go unused: vertically mounted inside or on the side of a server rack or enclosure. Not all vertically mounted metered PDUs are created equal, though. To make the best use of space, a rackmount PDU should have low-profile circuit breakers and a width optimized for side mounting to avoid interfering with access to hot-swap fans and power supplies.
3. Prevent accidental disconnects
Downtime caused by a plug getting bumped out of place is an occurrence that happens too often in data centers. Most rack PDUs rely on external clops or cable trays to secure plugs. While those methods of prevention are effective, they require additional time from staff and represent an added cost. Next-generation metered rack PDUs offer built-in IEC outlet grips, which provide the same prevention without the need for proprietary power cords or bulky additions.
The right metered PDU can provide all these resource-saving benefits. With the money, personnel power and space now available, your data center will be better able to meet changing computing demands.
Today, data centers are the pulse of corporate intelligence and business operations. With high costs for construction and operation, being able to minimize outside disturbance are top priorities. This eBook discusses the cost and security implications of maintaining a data center and the importance of having a reliable PDU to help you achieve continuous uptime.
