Connectorised cable assemblies for power cabling distribution infrastructure in data centres
Harting now offers a range of connectorised cable assemblies which provide a key element in the power distribution infrastructure of a data centre – by linking the uninterrupted power supply ( UPS ) and the power distribution units ( PDUs ).
The new cable assemblies address these challenges by combining a speedy plug and play approach during assembly and installation , with a flexibility whose benefits extend from the initial design and prototyping phase to operation and maintenance activities .
The assemblies are based on Harting ’ s Han-Eco modular connector family , which features a wide range of standard inserts that can be mixed in one connector , allowing the combination of various power requirements or even combining power and signal into a single connection point . For data centre applications , a typical installation uses 6B sized hoods and housings for cable-tobulkhead and cable-to-cable versions , with 4-pin and protective earth inserts for either 40 A or 70 A current handling .
When integrating a connector as the direct interface from the PDU , the user realises the full benefits of plug and play . There is no longer any need to hire a costly electrician , and since everything is pre-wired and pre-tested , wiring errors are virtually eliminated . n

Schneider Electric announces Indirect Air Economizer cooling
Schneider Electric has announced the the Ecoflair Indirect Air Economizer cooling solution , which uses a proprietary polymer heat exchanger technology to provide a cost-effective , highly energy efficient approach to cooling .
Ecoflair addresses the persistent challenge of maintaining optimum operating temperatures in data centres while keeping energy consumption to a minimum . The new system can reduce operating costs by over 60 % compared to legacy cooling approaches . This allows a greater proportion of data centre energy to be available for powering IT equipment , improving facility Power Usage Effectiveness ( PUE ). In addition , the design removes cooling equipment from the data centre floor freeing up valuable white space .
Ecoflair Indirect Air Economizers can reduce cooling operating costs by 60 % compared with legacy systems based on chilled water or refrigerant technologies . Even when compared with other indirect air economiser systems , the overall efficiency of Ecoflair has been found to be better by between 15-20 %.
Available in 250kW and 500kW modules , Ecoflair is designed to be flexible and offer greater customisation according to the cooling requirement and local conditions , simplified installation and associated expenses , and increased serviceability together with lowered maintenance costs .
The scalable approach makes Ecoflair particularly suited for colocation facilities rated between 1 and 5MW ( 250kW modules ) and large hyperscale or cloud data centres rated up to 40MW ( 500kW modules ). The modularity also allows the cooling to grow at the same rate as power upgrades . n
R & M is supporting the operators of local data networks by launching the Passive Optical LAN ( POL ). “ POL is the logical continuation of the Passive Optical Network ( PON ) technology in the building ,” says Lars Züllig , Product Manager FO LAN Cabling at R & M in Wetzikon . POL offers an alternative to traditional copper cabling . The fibre optic solution follows the principles of structured cabling , creating space in conduits and ultimately makes floor distributor rooms redundant .
Züllig added : “ Just one single mode fibre leads to the workplace whereas you used to find up to four bulky copper cables in the conduit . An upgrade of the transmission speed has no influence on the passive infrastructure and can therefore be used much longer . In addition the greater transmission distances of POL enable new cabling implementations and structures . POL particularly demonstrates its strengths in extensive installations with a relatively low density of use or at sites with a number of individual buildings .”
Another advantage is that the passive POL infrastructure may be less expensive than copper cabling . Ease of use , redundancy , reserves and the flexibility of the data connections are all influence investment . n
