AdvancedTCA® blades pack a lot of performance and many applications do not require the number of slots that a “big-iron” 12U/14U shelf offers. The six slots provided by the ATCA-6006 5U shelf supports 4 node slots or 5 nodes slots when configured with one Switch/HUB blade for semi-redundant operation; ample for many applications. The ATCA-6006 compact size and low weight makes it easy to slot in an existing rack to add functionality to an existing system with state of the art ATCA technology or to address remote field/edge applications where large 12U/14U systems are not practical due to space constraints nor necessary from a functionality point of view.

PRODUCT DESCRIPTION
The ATCA-6006 is a 5U ATCA shelf with 4 node slot & 2 hub slots. Blades lie horizontally and are cooled by two hot-swappable fan units on either side of the shelf, working in a push-pull arrangement to draw air across the blades from right to left. The backplane is configured with the two hub slots on the bottom and 4 node slots above them. Backplane is a full mesh, supporting dual-star fabric (base & fabric) with dual IPMB busses for management. The ATCA-6006 accommodates 6 RTMs (Rear Transition Modules) which are cooled by fans within the PEMs (Power Entry Modules). The two – 48V DC PEMs plug directly into the backplane from the back of the shelf.

REDUNDANCY FEATURES FOR 5x9s HIGH availability
The ATCA-6006 is designed for central office environments. Redundancy is inherent in the core design, including power, control, and connectivity. Dual redundant – 48V DC power is provided as required by the PICMG 3.0 specification.

SHELF MANAGEMENT
The ATCA-6006 Shelf Managers (SM) are integrated in the switch blade to reduce cost and space. The role of the SM is to monitor and control the shelf state, the presence and health of the shelf’s FRUs as well as blades that may be inserted into the shelf. The SMs arbitrate which blade is the Active Shelf Controller at power-up and from then on the Backup SM monitors that the Active SM is managing the system as well as updating its registers to take over if necessary. The ATCA-6006 can be operated with one shelf manager for cost sensitive application where total redundancy is not necessary. Failure of the SM in a non-redundant mode will cause the fans to turn on at full-speed to insure that the system continues operating safely.

MANAGED COOLING SUPPORTING
200W to each front blade and 20W to each RTM The ATCA-6006 provides a sophisticated thermal solution to meet the diverse requirements of the OEM common platforms. With two IPMI hot-swappable managed fan modules controlled by the SM, system noise is kept to a minimum while insuring that the shelf and blades are cooled sufficiently. RTMs are cooled by managed fans within PEMs allowing cooling for up to 20W per RTM. Fans run at maximum speed the moment that they are not controlled, thus insuring integrity of the system. Both rear and front fans run in a push-pull arrangement, drawing air across the board from right to left per ATCA specification. Air is filtered by a filter element that can be removed during operation for cleaning or replacement.

FLEXIBILITY
The ATCA-6006 shelf provides ample flexibility to allow initial system deployment with current technologies and in-field upgrades in the future. The backplane supports the full ATCA mesh, a super-set of dual-star base and fabric interfaces, with signal speeds up to 3.125 Gb/s. Thus, an initial deployment may utilize only the base interface and a subsequent upgrade may add modules supporting the fabric interface without the need to change the shelf or backplane. The shelf architecture enables OEMs to address multiple rack configurations – 19”, 23” and 535mm.

The backplane includes inter-slot update channels, synchronization clock buses, and metallic test & ringing signals.
