vii Regulatory Notices FCC S t atement This equipment has been tested and found to comply wit h the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. Th ese limits are designed to provide reasonabl e protection against harmful interference when the equi pment is operated in a commerci al environment.
viii CAUTION: Grounding is supplied by the gro und-prong on the 3-prong power cable. Do not attach a separate ground cable. Do not use adapter plugs. Do not remov e the ground prong from the cable. Ensure the ground connection on the power supply is correct and functioning before applying power to the T op spin system.
ix CAUTION: Never place your hand inside an empty card or module bay . Y ou should never have cause to place a hand anywhere inside the T opspin chassis. Unused card and module bays should always have a T opspi n cover over the bay to ensure proper safet y , ventilation, and cooling.

11 1 Features Overview The T op spin 270 Switched Computing System provide s data center managers with a high-performan ce, low-latency interconnect. • “System Architecture” on page 1 1 . • “About the T opspin 270 Chassis” on page 13 . • “Administrative Features” on page 20 .
12 Example The oper code field of the command out put id entifies the controller card as the active card (normal) or the hot standb y card (standby). By d efault, when you power on a T opspin 270, the card in slot 1 1 becomes active and the card in slot 12 becomes the standby .
13 Fabric For redundancy , InfiniBand Host Channel Adapters (HCAs) can be dual-connected to a redund ant pair of T o pspin 270s. In an InfiniBand fabric that includes more th an one T opsp in 270: if the subnet manager on the T opspin 270 that is acting as the master fails, another su bnet man ager will take over within seconds.

15 Chassis Slot Numbering Slot numbers are p rinted on the chassis for easy identificatio n. Figure 1-3: Chassis Slot Numbering in Fr ont (Non-port Side ) Power Supply ID 1 Power Supply ID 2 Fan ID 2 .
16 Figure 1-4: Chassis Slot Numbering in Back (Service Side) Dimensions • Height : 6U unit • Wid t h : 17.04” • Depth : 8” - 23.7” • We i g h t : maximum 106 pounds (full chassis configurat ion with 4x copper Li ne Interface Modules) Connections • 96 ports of 10 Gbps 4X Copper InfiniBand.
17 • The power supplies are 1U, 48V , 1200W • The supplies provide regulated +48V DC to all other modules in the system. • Each power supply has self contained fans for cooli ng. Fan T rays Refer to “Installing a Fan Module” on page 41 for installation instru ctions.
18 Understanding the Core Slot to Mgmt Interface Module Connection Each Core slot in the chassis (refer to “The Core Slot” on page 18 ) is connected to 1 port on the Management Interface mo dule. The controller (fabri c interface module inserted in the core slot) selects the Management Interface module to which it will connect.
19 • At least one Fabric Controller module must be inst alled in the Core slot for the chassis to boot. • When a module is installed in a Co re slot, it acts as either the master or standby controller for the chassis, with all modules in the system being slaves to the master controller .
20 Administrative Features Real-T ime Clock The T opspi n 270 maintains correct time regardless of power conditions or con nectivity . Latency The T opspi n 270 has port to port latency of less than 600ns.
