Demystifying the Packet Power LED data stream

Posted on Wednesday, July 27, 2016 by Alan Katz

Packet Power uses the local LED display on our newer meters to show more than just amps by phase. That's good, but it can get a little cryptic. Is "con" a good thing? If so, why don't you see it all the time? What does "no" mean? Why does Packet Power use a "U" to communicate voltage? And what's up with the red and green blinking lights? 

Read on for a quick overview of all that your power meter is telling you.

Creative monitoring:  How to know -30°F is no problem

Posted on Tuesday, June 7, 2016 by Troy Wyborny

The Midwest region of the United States experiences a wide temperature range from -30°F (-34°C) in the winter to over 110°F (45°C) in the summer. Well-functioning heating and cooling systems are critical in this environment.

Like many efficient data center operators, Data Realty, a co-location company based in the heart of the Midwest, leverages outside air during the colder seasons. But what about when it is really cold? They came up with a clever use for a Packet Power product to help ensure freezing temperatures didn't negatively impact their business.
