Key Features of Polar PDUs

Learn about the many useful features of Subzero Engineering’s Polar PDUs

Secure Link

Secure Link consolidation technology reduces costs and decreases installation time by allowing you to link up to 32 PDUs under a single IP address using standard Ethernet cables. Enjoy features such as outlet grouping, data logging, threshold alarms, and PDU cloning. Adding a second IP address provides failover capability, which allows functioning PDUs to continue communicating if a PDU in the array loses connectivity.

High Ambient Temperature Rating

Designed to withstand the heat loads of any vertical exhaust duct or hot aisle containment environment and allows full implementation of the newest ASHRAE recommendations. Perfect for installation in high-density application cabinets, all Polar PDUs are optimized for use in ambient air temperatures up to 149°F (65°C) at the input power rating (kW), ensuring that they will perform reliably in any hot aisle environment. In addition, Polar PDUs feature a low-profile design that does not block airflow.

Locking Outlets

Polar PDUs with IEC outlets come standard with locking outlets. This feature fastens straight equipment power cords to the PDU without the need for proprietary accessories, allowing you to save on additional accessory costs.

UL Listings/Circuit Protection

All PDUs are UL® 60950 listed and CE marked. They utilize100% rated, slim-profile hydraulic magnetic breakers to minimize nuisance tripping due to temperature variations and minor overloads.

Cabinet Access Control with Polar PDUs

Polar PDU Cabinet Access Control provides an easy-to-use and economical networked electronic lock solution for data center cabinets.

Integration with Polar Power Distribution Unites (PDUs) removes the need to power and network the locks separately. Use a single network connection to deliver power, environmental monitoring, and access control.

All PDUs with auxiliary ports (manufactured after March 2017) support Cabinet Access Control. This allows Polar PDUs to provide a networked locking solution for cabinets. Users can remotely control and monitor cabinet access and keep a log for security requirements. One network connection can support up to 16 cabinets or 32 locks.


Key Features

  • Electronic swing handle with integrated sensors for lock and latch status, monitoring and alarm functions
  • Power for lock operation delivered through Polar PDU
  • Remote unlock capability
  • User-configurable unlock time delay
  • High-security lock with mechanical key override
  • Reader recognizes existing employee 125kHz or 13.56 MHz RFID cards
  • Bi-color LED (blue/magenta) to indicate lock and handle status
  • Event logging for auditing purposes, regulatory compliance
  • Integration with LDAP and Radius for added security
  • High temperature rating supports use in hot aisle environments
  • Must be used with Polar PDUs that have auxiliary 1 and 2 ports (PDUs manufactured after March 2017)

Power Management from Subzero – Polar PDUs

Polar Power Distribution Units (PDUs) provide the ultimate solution

Polar Power Distribution Units (PDUs) provide the ultimate solution for combining cabinet level power management, environmental monitoring, and cabinet access control in multi-tenant and enterprise data centers. With innovative features such as Secure Link IP consolidation and integrated Cabinet Access Control, Polar PDUs offer the quickest and lowest cost deployment among all intelligent rack PDU solutions in the industry. With high ambient temperature ratings, locking outlets, models that support up to 100 Amps, and a high number of C13 and C19 outlets, Polar PDUs are the ideal solution for any high-density environment.

Check the blog over the next few weeks for more information on our Polar PDUs.

NYC Raises the Roof

New York City Approves the Polar Cap 2 Retractable Roof

In a Buildings Bulletin dated October 19, 2016, NYC Buildings Department establishes acceptance criteria for retractable-type horizontal cold aisle containment systems installed in information technology equipment areas.

The installation of a retractable-type horizontal cold aisle containment system installed in information technology equipment areas (horizontal cold aisle containment system) is used to minimize the consumption of energy by providing an overhead thermal containment barrier used to create a cold aisle. However, the overhead containment barrier may obstruct the performance of code-required fire suppression systems (BC Chapter 9). This bulletin establishes acceptance criteria for horizontal cold aisle containment compliance with the NYC Construction Codes.

The Subzero Polar Cap 2 is a fully electric roof system that retracts into a metal housing when the fire suppression system is alarmed. Having a pre-action system that reacts to a smoke detector will ensure that the containment roof is fully retracted long before the fire suppression system is discharged. Additionally, the roof material meets the stringent flame and smoke requirements of ASTM E-84 Class A Rating. The Polar Cap 2 can also be manually opened and closed when maintenance is required above the containment space.

Warming Your Data Center

With consistent intake temperatures, data centers can increase cooling set points, creating a warmer data center, which lowers cooling costs

For decades the idea of running a hot or warm data center was unthinkable; driving data center managers to create a ”meat locker” like environment – the colder, the better.

Today, the idea of running a warm data center has finally gotten some traction. Major companies like eBay, Facebook, Amazon, Apple, and Microsoft are now operating their data centers at temperatures higher than what was considered possible only a few years ago.

Why? And more importantly… How?

The “why” is easy.
For every degree the set point is raised, the cost of cooling the servers goes down 4%-8% depending on the data center location and cooling design. Additionally, some data centers can take advantage of free cooling cycles when the server intake temperatures increase. This is of course taking into account the manufacturers recommended temperature settings, and not surpassing them.

Now on to the “how”. Or we might ask why now? What changed?
The answer has to do with the ability to provide a consistent server intake temperature. Inconsistent intake temperatures are a result of return and supply airflows mixing. When this happens it creates “hot spots”, which causes cooling problems. Without a consistent supply temperature the highest temperature in those “hot spots” would determine the data center cooling set point temperature, resulting in a lower set point.

A few years ago containment was introduced to the data center industry. Containment fully separates supply and return airflow, which eliminates “hot spots” and creates a consistent intake temperature. Containment is the key to accomplishing consistent intake temperatures. With consistent intake temperatures data center managers can increase cooling set points, creating a warmer data center. A warmer data center means less money spent on cooling costs.
