Pic.1-2 Vertical PDU 2、System Feature
2.1、High performance
◆The double-precision high-tech calculation method provide accurate electric energy measurement and power factor data for a single socket.
◆Colored LCD display visually display information such as voltage, current, power factor, electric energy, IP address, temperature and humidity, CAN/485 hardware address, etc
◆High efficient data processing methods, real-time data monitoring for input current, voltage, power, power factor, electrical energy, frequency, etc., also the monitoring and control PDU can display current, power factor and energy of each socket, with curve image display function
◆ Available for remotely turn on/off a single socket
Monitor and control PDU could management each sockets through HTTP, SNMP, SSH and other network protocols , At the same time, various protocols can provide encrypted SSL to make remote control more secure and reliable.
◆Socket metering function provided
Provide users with a basis for accurate calculation of PUE, plan and optimize the energy consumption of the data center based on this, reduce costs for load balancing and IT environment set up.
◆ Customized allowed alarm threshold set can warn potential circuit overload by real-time and remote alarm lower the risk.
◆ Advanced switch function, can realize user-defined logic control and independently realize the switch action and schedule of each socket position, also take intelligent actions according to environmental changes.
The user can control the PDU output switch according to the current threshold and temperature threshold, and provide multiple alarm at the same time. There is a parameter copy function between the sockets. After setting the parameters of one socket, it can be quickly copied to other sockets. With socket management function PDU, each socket can be controlled according to the time setting by user, it can realize 20 user-defined time period editing to meet the complex needs .
◆ Socket sequencing delay, in order to avoid circuit overload, and can customize the time
When switching sockets or powering on, the power-on time interval can be flexibly set between sockets, which is conducive to stable operation of the load and avoids surges.
◆ With socket grouping management function
PDU with single socket management, users can customize socket grouping, flexible socket grouping is conducive to user classification management of sockets. The hardware is also divided into 3 groups independently, each with 8 sockets. Each 8-bit socket of the three-phase PDU is also electrically isolated.
◆ Users can access and configure via a secure Web, SNMP, SSH or Telnet interface, easy to operate and integrate.
◆ Provide 2ways temperature and humidity sensor, 3 ways input and 1way output port
◆ Provide isolated CANbus, RS485 serial networking mode
◆ Compatible with Kotohira system SNMP Link network management system.
SNMP Link provides power equipment management and environmental parameter detection for the dynamic environment monitoring system of Kotohira system small and medium data centers. The equipment that SNMP Link can manage includes power distribution cabinets, PDUs, ATS, UPS, air conditioners and other equipment. For details, please refer to the SNMP Link description.
2.2、Multiple network service
Provide HTTPS management, support TLS Encrypted authentication HTTP supports standards above TLS1.0
Provide SNMP v3 Agent, support DES or AES authentication method. Provide MD5 or SHA private encryption Provides SNMP function for re-developing and facilitate the integration of other software with SNMP network management SNMPv3 also provides encryption protection.
Support Telnet and SSH
Support network firewall, Provide data packet filtering, anti-PING Provide NTP time synchronization settings
Network clock synchronization,
Provide operation, event log and battery time record
Event log records operation, alarm, device data, input and output sockets data information etc.
Support PDU upload and download power records.
Above function is mainly used for rapid configuration of batch PDU. Users can set the parameters then download , and upload the parameters to other PDUs of the same type to achieve rapid device configuration.
2.3、Safety
Support TLS Encrypted authentication, SNMPV3 communication, Alternative encryption, SSL mail sending, support network firewall
All external sensor interfaces and communication interfaces are isolated.
Support Memory recovery speedy under abnormal
Latest Linux kernel version 4.0 and encryption library available for security vulnerabilities restorage Online software upgrade available
