THE wide range of IT security solutions of the system supplier for the industrial electric as well as the information technology and telecommunications market from Herborn has become larger with the advent of the Rittal Power Control Unit (RPCU).

Use of a so-called web terminal strip is recommended when a high degree of security by efficient administration of active components is necessary in high-end IT network architectures, e.g., in telecommunications, financial service environments or industrial automation.

Anyone with a knowledge of network architectures using active equipment is aware of the problem: How can the constant failsafe and secure operation of all active consumers be ensured from a remote vantage especially in distributed system architectures?

Rittal exhibited at CeBIT 2002 an RPCU - a simple but very efficient solution. With 1HU and 200mm depth a very compact design, the web terminal strip can be addressed by the data network via HTML or SNMP and in this way it supports efficient remote control via intranet or internet.

Integrated in the RPCU is a web server so all common web browsers can be used to gain information on the current state of the IT system and take corrective action within a very short time. There is no need to purchase or install any software.

The web terminal strip has SNMP capability and fits easily into any existing SNMP management system while providing extra setting options via MIB. If the user wants to use the log functionality but has no SNMP management system of his own, Rittal's SMNP Manager is a fitting solution.

Most of the problems in a network can be remedied quickly by turning off and again turning on components such as servers, routers or hubs. The necessary commands can also be transmitted to the RPCU as SMS via mobile phone from any place.

The sequential starting sequences of the web terminal strip ensure in any situation that when the system is re-started, the ports are activated automatically one after another. This avoids overload of the network by simultaneous starts of several consumers.

The RPCU integrates 8 terminals, six of which can be controlled individually. The terminals are powered by two circuits, one circuit supplies the two non-controlled and the controlled terminals and the other circuit can feed another four controlled terminals.

In addition, the system has RPCU-internal temperature measurement and two digital alarm inputs to which additional external alarm sensors can be connected. These messages are used internally to cause voltage disconnects to individual terminals.
