NETIO 4C | NETIO products: Networked power sockets

NETIO 4C is a small 110/230V PDU (Power Distribution Unit) with four controlled IEC-320 C13 (max 8A) power outlets. It includes an Ethernet switch and two LAN ports for network connections. Each of the four power outputs can be individually switched on/off over the web, from a mobile app, or using various M2M APIs (SNMP, MQTT, XML, Modbus/TCP, ..). Custom Lua scripts can run directly in the NETIO 4C device. As a distinctive feature, NETIO 4C provides a RS-232 serial port (3-pin) that can be controlled with a Lua script or used as a remote serial port. 

The NETIO 4C smart PDU is designed to distribute power in racks. Use the product whenever you need to individually control 110/230V power outlets. Individual power outputs can be controlled by a mobile app, by a computer program (via M2M API) or by a custom script (Lua) that runs directly in the NETIO 4C smart PDU.

Many customers use NETIO 4C to ensure a defined power-up sequence after power failures and to switch outlets on/off at specified times (Scheduler function). Another frequent application is a “PING Heartbeat” – automatic restart solution (IP WatchDog function).

Built-in Ethernet switch

The two LAN ports of NETIO 4C are connected to an internal Ethernet switch. This makes it easy to daisy-chain NETIO 4C devices and connect them all to a single LAN connection.

Functions for ordinary IT users

  • Outlets can be controlled over the Web or with a mobile app (iOS / Android).
  • The switching of outlets can be time-controlled by the Scheduler with a graphical interface.
  • The IP WatchDog (automatic restart) function controls the 230V outlet by detecting “ping” responses. It can be used to restart unresponsive servers, routers or microwave links.
  • ANxx (Application Notes) is a library of examples of using NETIO electrical outlets in various applications, connecting to third-party software, and so on.

M2M API

The NETIO 4C smart PDU (Power Distribution Unit) offers unmatched support for many network protocols that can be used to control each outlet. These network protocols are called the M2M (Machine to Machine) API (Application Programming Interface).

Security (ssl)

NETIO 4C supports enhanced network security. The HTTPs protocol establishes a secure connection between the browser and the web server.

The third SNMP v3 generation offers higher security in comparison to previous SNMP versions. The MQTT protocol for IoT cloud applications includes SSL security. 

Monitoring of connected devices (IP WatchDog function)

The IP WatchDog function of NETIO 4C smart PDU monitors ping (icmp) responses. When the monitored device is powered from one of the controlled electrical outlets, NETIO can restart it by briefly disconnecting the power.

As a unique feature, users can use Lua scripts to write more complex conditions for monitoring other devices. For example, the correct operation of other devices (heartbeat) can be checked by parsing XML files, loading web pages, and so on.

RS-232 serial port of NETIO 4C

The NETIO 4C smart PDU provides a RS-232 serial port at a 3-pin connector. The serial port can be used as a remote serial port (a tunnel from a TCP connection to the serial port), or controlled with Lua scripts.

Lua scripts can send strings to this serial port and read any responses. This makes it easy to connect various industrial devices in order to, for example, react to a high temperature sensed by a RS-232 sensor by switching on a particular outlet.

Lua – Programmable scripts

NETIO 4C smart PDU can run custom scripts. NETIO 4C supports the Lua scripting language. The user script (or several scripts) runs directly in the PDU. The scripts are written in the web interface. A library of sample scripts is being prepared as NETIO Application Notes.

Lua scripts can send e-mails, read values from RS-232, or switch individual outlets on/off.

User Lua scripts can also:

  • Switch individual power outlets on/off
  • Send e-mails
  • Send and receive icmp ping
  • Download and parse XML files from other devices (from a given IP address)
  • Receive http get requests (CGI scripts)
  • Work with time (Scheduler)

NETIO 4C applications

The NETIO 4C smart PDU is typically used to distribute electricity in a 19" rack (cabinet) in a data center. Each IEC-320 outlet can be switched on/off, and several NETIO 4C smart PDUs can be connected in series thanks to two LAN ports.

Delayed switching-on of individual outlets when recovering from a power failure prevents circuit breakers from tripping. NETIO 4C features an electronic fuse as well as overvoltage and surge protection.

FAQ

Expand all

I forgot my password. How can I reset NETIO 4All to factory settings?

The proper procedure is described in the manual – look for “Forgotten password. Restore Factory Defaults”:

If you forget your password, it is possible to manually reset the device to factory defaults. This is done by pressing and holding outlet buttons 1 and 2 with device on. Hold the buttons until the device beeps 2 times. During the resetting process, all the outlet LED are blinking red. As soon as reset is completed, the device beeps 2 times.

What is a “serial port tunnel“?

A serial port, accessible at the 3-pin terminal block, can be bound to a specific TCP port in the settings. After that, it is possible to open e.g. a Telnet connection to IP:Port on a PC and the characters that you type in the terminal will be relayed to the physical serial port. RS-232 baud rate and other parameters can be set in the NETIO 4C web configuration interface.

How to mount NETIO 4C into a 19" rack?

In the Accessories section, look for the bracket to mount two NETIO 4C smart PDU devices side-by-side as a 1U unit into a 19" rack.

A bracket for mounting one NETIO 4C into a 19" is coming soon.

Is NETIO 4C a smart PDU or a smart power strip?

 The terminology is not settled; however, in general a PDU refers to a device intended for a 19" rack. IT equipment also typically uses IEC 60320 C13/C14 power connectors.

Products with wall-like 230V outlets (Type F (Schuko), Type E, ...) are more often called “smart sockets”.

What is the purpose of the USB connector at the NETIO 4C front panel?

The connector is for factory use only.

I unpacked the NETIO 4C smart PDU, how do I set it up?

See the printed QIG included in the package for the proper procedure.

Connect NETIO 4C to the Ethernet (LAN) and run the “NETIO Discover” application (Windows / Java version). The application discovers the device IP address, and lets you open its web interface with a single click.

The default login/password combination is “admin” and “admin”.

I forgot my password. How can I reset NETIO 4C to factory settings?

The proper procedure is described in the manual – look for “Forgotten password. Restore Factory Defaults”:

If you forget your password, it is possible to manually reset the device to factory defaults. This is done by pressing and holding outlet buttons 1 and 2 with device on. Hold the buttons until the device beeps 2 times. During the resetting process, all the outlet LED are blinking red. As soon as reset is completed, the device beeps 2 times.

What does NETIO 4x mean?

NETIO 4x refers to all NETIO 4 / 4C / 4All products.

It is often mentioned that NETIO 4x smart sockets support SNMP v3. Does it mean that SNMP v1 is not supported?

SNMP v3 is an extension of SNMP version 1. NETIO products support SNMP version 1 only for reading the status. For switching sockets, it is necessary to use the more secure SNMP v3.

In general, we recommend to use SNMP v3 only (it uses SSL security).

Can NETIO 4x switch an output on or off at a specified time?

Yes. Switching sockets on and off at given times can be configured using the “Scheduler” function and its graphical interface.

Another option is to write a Lua script. Such a script can also communicate over the Ethernet and makes some tasks easier to set up. 

Is it possible to control NETIO using an IoT cloud?

Yes, NETIO 4x products (4/4All/4C) support MQTT (MS Azure) for connecting to IoT (Internet of Things) applications in a cloud.

Is it possible to control NETIO 4x outputs with a mobile app?

Yes, use the NETIO Mobile app. The mobile phone and all controlled devices must be in the same network. The app supports NETIO 4/4C/4All and can control multiple devices.

Does NETIO support daylight saving time?

Yes, all NETIO 4x products (4/4All/4C) feature the Scheduler function that switches the outputs on or off at the specified hour and minute. The time is synchronized automatically according to the selected time zone. The daylight saving time is set automatically and cannot be disabled.
