The increased requirements of modern IT infrastructure in data centres demand a maximum of physical safety and security. The Rack Management System guarantees clear recording and traceability due to its personified access control at the rack level. The system monitors all physical parameters in the data cabinet, thereby ensuring a high degree of availability of the entire system. Wireless transmission handles drastically reduce installation effort and investment costs. E-mail or SMS alert, integration into the building management via SNMP as well as expandability by simply adding additional modules complete the functionality.
