Did you know that Server Technology allows, and even encourages, its customers to build their own PDUs? Now, to be clear, we are the ones who actually build the PDUs, but we do feel strongly that you should have control over that process. We let you do this through a web tool we call “Build Your Own HDOT PDU.”

The first step in building your own PDU is to figure out what you want, right?


Well, not so fast. Since there are five product types to choose from, the first step is to decide which one best suits your needs. We’d like to take a minute to go over the options.

Metered. The most basic form of rack mount power strip, that you can configure, is what we call Metered. The Metered unit will provide information on input current via a display on the PDU. This is helpful for preventing overloads and simplifying the process of balancing three-phase loads. This is the best choice for those who want to keep it simple and are not interested in getting rack level data and control via their PDU.

Smart. If you would like to have this information delivered to you in order to make the job of managing the power strip a little easier and less manual, the next step is to look at the Smart series. Our Smart rack-mount PDUs include the features of Metered power strips, and they provide these input power measurements to you via your network or a serial connection. They can be also configured to send email alerts about different power and environmental conditions. As the name Smart implies, this is the first step toward rack-based power intelligence.

Smart POPS. If you’re the type that takes it to the next level, then Smart POPS is for you. The acronym POPS stands for “per outlet power sensing,” and Smart POPS PDUs provide accurate power monitoring at the outlet level along with all of the features that you would find in a Smart PDU. In the world of monitoring what’s going on inside your rack, this is the entry-level way to obtain outlet by outlet electrical monitoring.

Switched. Depending on your operation, it might make sense for you to have the ability to turn on, turn off, or reboot outlets either individually or as a group. If you have these types of control needs, then the Switched unit is the one for you. Switched provides the same features as a Smart POPS along with the ability to control the unit, lockout certain outlets, and control power sequencing to reduce inrush and increase your ability to shed load in a logical fashion.

Switched POPS. If you were thinking, “well, I’d love to have everything that you’ve mentioned,” then there is one last option for you to consider. All of the smart, switched, and POPS features are combined into a product we call Switched POPS. This unit combines all of the features into one feature-rich PDU. In fact, it is the most sophisticated power distribution unit on the market today.

While this is a lot to think about, identifying how you engage, control, and manage your rack-level electrical loads is the best and first step in the process of building your own HDOT PDU. We will return next week with the rest of the lesson to help you get your units into production.

If you can’t wait, please visit our Build Your Own HDOT PDU tool on the Server Technology website. Roll up your sleeves, and let the PDU building begin.
