Table 17 Minimum Clearances (continued) Doors: rack doors must be at least 1.5 inch (3.81 cm) away from the front and rear of the enclosures and be perforated with a minimum 50% open pattern across the entire surface. Cabling Front: n/a Rear: 30 inch (76.2 cm) total clearance Sides: n/a Rack Mounting Kits Table 18 Mounting Kits Node and Drive Enclosure 692982-001 for (M6720) 4U24 HDD chassis assembly 692981-001 for (M6710) (7200) 2U controller chassis assembly and 2U24 HDD chassis assembly Service Processor 683811-001 Processor 1U Mounting Kit Four-Post Shelf Kit The four-post shelf kits allow the drive enclosure and components to be mounted in a variety of four-post racks. Each enclosure or component requires its own mounting kit. NOTE: Do not stack the enclosure on top of another one. Four-post shelves are mounted to the front and rear rails of a four-post rack. Each side requires two shelf halves and the corresponding mounting hardware. The shelf halves are expandable to fit racks of different depths. Front shelf halves have left and right pieces, while the rear shelf half can be used on either side of the rack. When the installation is complete on both the left and right sides, the equipment can be placed on the shelves and secured to the RETMA rails. Redundant Power Requirements Each storage system component is supplied with redundant PCMs. The controller nodes and drive enclosure are designed to continue operating even when AC power is lost to one of the PCMs. For this feature to operate properly, each power supply line cord within an enclosure must be attached to an independent electrical source, each controlled and protected by its own circuit breaker. Multiple outlets in a power distribution unit or power strip do not constitute an independent electrical source. Additionally, each line cord must be plugged into an outlet that is capable of supporting the entire load of its enclosure. CAUTION: The PDUs are not provided with the installation kit. Verify the PDUs meet the minimum power requirements before powering on the system. Special consideration must be given to this requirement. Failure to do so may result in the overloading of the branch circuit if a power supply fails, and shuts down the storage system, and cause similar failures in all the equipment connected to the branch circuit. CAUTION: AC line cords should be securely attached to the customer PDUs and outlets with cord-retention mechanisms to prevent accidental disconnection during service activities. HP provides cord retention mechanisms on HP power supplies but does not supply retention devices for connection to the customer PDUs or outlets. NOTE: See "Power Requirements" (page 22) for complete details about power requirements. 32 Third-Party/Existing Rack Mounting
