The name "switched rack PDU" implies three different things. I'll explain each one individually here to help you understand how they all fit together.

Switched Rack PDU example: Remote Power Switch
This is one example of a switched rack PDU, the Remote Power Switch AC from DPS Telecom.

Power Distribution Unit Definition

PDUs are industrial-grade power strips used to power servers and telecommunications equipment.

The acronym "PDU" stands for Power Distribution Unit. PDUs are, essentially, industrial-grade power strips used (in most cases) to power servers and telecommunications equipment.

You'll generally have too many devices at a site to plug them all directly into your power supply. You need PDUs to distribute your site's power to each device. This is possible because a PDU turns one (or a few) power inputs into many (usually about eight per device) power outputs.

PDUs are available in both AC and DC models to match the power in use at different kinds of sites.

"Rack PDU" Definition

A rack PDU is designed to be mounted in an industry-standard equipment rack.

Now let's add another layer to our definition by adding the word "rack". A "rack PDU" is a PDU that is designed to be mounted in an industry-standard equipment rack. These are typically either 19 inches or 23 inches in width. Height can vary from PDU to PDU, but most are just one "rack unit" high. This translates to about 1.75 inches.

A rack PDU is different from other kinds of PDUs that are designed to be wall-mounted or attached to the side of an equipment rack. These other PDUs conserve valuable physical rack space in cramped equipment racks, but they do increase the distance between the power outputs of the PDU and the power inputs of the devices that will receive electricity.

"Switched PDU" Definition

A switched PDU is one that can toggle power on and off for individual power outputs.

Now that we know what a rack PDU is, let's take a look at the phrase "switched PDU". Switching, in the PDU context, means toggling power on and off for individual power outputs. How many times have you had a piece of equipment fail and all that was required to fix it was to simply turn the unit off and then on again? A PDU acts as a master switch that can power cycle equipment so that you don't have to send a tech four hours just to turn a unit off and then back on.

Switching opens up a whole new world of remote management possibilities for your servers and other devices. Now, with a few clicks or keystrokes, you can remotely reboot servers, activate backup systems, power devices down ahead of a flood or other natural disaster, and perform other valuable power control functions.

This is why a switched PDU greatly enhances your ability to remotely manage power to your devices. You have more control over your devices remotely than you would normally.

"Switched Rack PDU" Definition

A switched rack PDU is a power distribution unit that can be mounted on an industry-standard rack, and has the capability to toggle power on and off for individual power outputs remotely.

OK. Let's put it all together. A "switched rack PDU" combines the strengths of a rack PDU with those of a switched PDU. This kind of power distribution unit is designed to be installed in your equipment racks to distribute power to your telecom equipment. In the event that you need to turn on, turn off, or reboot one of your devices, you can use the remote switching functionality of your switched rack PDU to handle that task from your desk - without driving to the site.

The Strong ROI of a "Switched Rack PDU"

By installing in industry-standard equipment racks, switched rack PDUs allow for a very clean and professional installation. With remote switching functions, switched rack PDUs dramatically reduce the costs associated with driving out to sites just to activate or reboot a remote device. A switched rack PDU will ultimately save you a great deal of time and money, as well as make your customers, your boss and your techs happy.

The Remote Power Switch AC

The Remote Power Switch AC by DPS Telecom allows you to remotely power cycle your equipment. One device has the capacity to cycle up to eight other devices, right from your central office. Never again will you have to send a tech to a site just to turn something off and then on again. Simply plug your devices into the back of the unit which is then connected to a power supply, similar to a surge protector. The Remote Power Switch then takes the power and allocates it to each of the connected devices. If one of the devices stops working, you can use the Remote Power Switch to turn it off and then on again, without driving to the site. Whats more, the Remote Power Switch also has RTU functionality so that you can monitor sensors and other devices all from one unit.

For complete environmental visibility, the Remote Power Switch also monitors internal temperature, external temperature, and current draw for each input. This is important at your unmanned sites, where you need to detect and respond to network issues remotely.

Using any PC on your network, you can operate controls, as well as check temperature at the site, and keeps tabs on power consumption - all without any windshield time. Unlike other power switching devices, SNMP compatibility makes the Remote Power Switch special. You can choose up to 8 different notification devices - any combination of SNMP managers and email addresses.

Need to control a lot of power at a single site? You can use the expansion port on the back panel of the unit to daisy chain many Remote Power Switches together. Linked switches will act as a single unit, making them easy to control using the web interface.
