With power and cooling of up to 700W per slot, MaXum 550 is considered the industry’s most powerful ATCA chassis, supporting HPC (High Performance Computing) applications, which may include hundreds of high-power cores. By combining energy efficient pressurized cooling with an innovative thermal design that includes a large air inlet and outlet, Maxum 550 14-Slot offers record-breaking cooling capacity into a standard 16U DC and 17U/18U AC chassis.

Massive power distribution
MaXum550 breaks the power distribution barriers. Its innovative easy-connection DC power entry module supports a massive 250A power feed. The integrated field-interchangeable AC solution features up to 20kW of AC power with N+1 or N+N redundancy and full current sharing. The DC version features redundant power entry of -48VDC/-60VDC.
Industry-leading cooling power
With pressurized front-to-back cooling of up to 700W per slot, MaXum550 leads the industry, supporting any current and future blade cooling requirements. Despite its intensive cooling capabilities, through its Dynamic Cooling feature, Maxum 550 14-Slot is extremely energy efficient, delivering the exact amount of cooling necessary for each blade at all times.
Advanced 40G backplane 
Asis is renowned for pioneering the “Dual-Dual Star” topology. MaXum550 takes a giant step forward, offering Dual Star, Dual-Dual Star and Full Mesh topologies in an ultra-fast 40Gbps backplane. The new architecture dramatically increases the throughput and the amount of I/O for extremely high-throughput low-latency applications, such as deep packet inspection, network/IT security, and real-time high volume data processing. In addition, Maxum 550 14-Slot is the first chassis to bring 40G full mesh topology on a 14-slot configuration, opening new horizons for massive-scale data acquisition and NFV/SDN applications.

Field interchangeable Integrated AC/DC solution – MaXum 550 features a field-interchangeable integrated AC solution, which for the first time, enables VAR/integrators to order enclosures without selecting, in advance, the environment in which they will be implemented (DC or AC), thereby   providing outstanding flexibility and time-to-market.
Next-generation shelf management
MaXum550 features Pigeon Point’s new-generation ShMM 700 redundant shelf manager. The new shelf manager offers major advancements in quality, stability and cost-efficiency.
