i-PDU
The i-PDU solution is a simple effective intelligent power bar, that directly connects to just 1 of the 14 plug and play i-BOX sensor ports, this has the benefits of real time, bi-directional communications with each connected i-PDU over a standard Ethernet Network, providing not only monitoring and recording of power consumption values, but to actively control the operation of the PDU sockets.
Transaction data is buffered at the i-box and synchronised automatically with the central management software, each i-PDU stores its start-up configuration data. So even during a full power down the PDU will start-up as configured.
The i-PDU contains a precise measuring device that samples for KWH readings 4,000 times per second, readings are reported at scheduled intervals to the i-box. |

Main configuration Screen for i-PDU
The Main PDU sensor screen provides a clear overview of the of the current
status of the i-PDU, a real time graph is provided for an instant visual
analysis of the recent transactions, each i-PDU can have its own text label. |

The power strip transaction logging is fully configurable as follows:
Reporting Frequency: This is how often the live reading on the sensor is transmitted to the PC.
Read Frequency: This is how often the i-Box unit interrogates the sensor for a reading.
Store Frequency: This is how often the readings are stored on the local database; note that when the i-BOX is connected to the PC software readings
are also stored to the PC hardware at intervals as set on the reporting
frequency. Each i-BOX can store locally a maximum of 5,000 readings; this
can be expanded to 16,000 with additional memory. Storage at the PC is
only limited by the size of the hard disk.
Maximum/Pre-Alarm/Minimum/Change can be defined for both voltage and current. Once the reading exceeds these limits it will trigger an alarm
and the appropriate transaction will appear on the main screen, providing the
sensor’s type, alarm description, i-BOX name and sensor ID. These alarms
can be configured to transmit SNMP traps or email/SMS via a SMTP server. |

Details Screen for i-PDU
The status of the sockets is displayed on the left hand side. Each status has a unique colour. Colour green means that the socket is switched on and colour red indicates that the socket is switched off. If there is a fuse failure in any of the sockets, it will become amber and the appropriate transaction will appear in the main screen. There is a space in front of every socket to enter a brief description of the equipment connected to that particular socket. |

Delay Start-up column includes the number of seconds before a socket is activated when the PDU is switched on. If the input value is zero, the socket
will not be switched on. (Range: 0s ¨ 255s)
Delay/Current column indicates the upper limit of the current in the unit before a particular socket is switched on. For example if the input value for a particular socket is 5, it will not be switched on until the current in the unit has dropped down to 5 amps or less. If there is a mismatch between the database and the PDU settings, these fields become yellow. All you need to do is to press the save button to synchronize the database.
Smart Start
It is possible to configure the sockets in the order that you wish them to start with perhaps less delay between ports utilising the current sensing feature, as this will automatically delay the next socket until the current has been sensed to be below the configured threshold.
Normal Current: shows the normal amount of current consumed by each device. This value is determined by the user and is merely for user's information and has no effect on the operation of the PDU.
Permit to work & Date/Time: the last two columns display the last
explanation of why a socket was switched on or off. The user is forced to complete a pop up window with the reason why the socket status has been manually changed; this transaction is stored on the server software with time/date stamp and operator responsible.
Overall delay: This is the delay that mains has to be continuously present before the first socket delay timer starts. By setting individual i-PDUfs with a sequenced start-up will avoid surges of power on equipment connected to i-
PDUfs fed from the same power circuit. This avoids multiple attempts for
mains to return and the surges this can cause.
Threshold Current is the maximum current you can obtain from the PDU.
Pressing the End delay button will terminate any delay time and all the sockets in the unit will be switched on. Reset Power button will bring the value of total power back to zero. |

States to be indicated on PDU relay LED:
1. Normal: Power switched on, power sensed –LED on solid
2. Fault Feedback: Power switched off, power sensed –0.5 sec on/off flash for 3 seconds, off 2 seconds
3. Fuse Fault: Power switched on, power not sensed –80 ms seconds on/off flash
4. Socket Off: Power switched off, power not sensed –LED off. |
