11 1 Features Overview The T opspin 270/Cisco SFS 7008 Server Switch provides data cen ter managers with a high-performance, low- latency interconnect. • “System Architecture” on page 1 1 . • “About the T opspin 270/Ci sco SFS 7008 Chassis” on page 13 .
12 Example The oper code field of the command out put id entifies the controller card as the active card (normal) or the hot standby card (standby). B y default, when you power o n a T opspin 270/Cisco SFS 7008, the card in slot 1 1 becomes active and th e card in slot 12 becomes the st andby .
13 Fabric For redundancy , InfiniBand Host Channel Adapters (HCAs) can be dual-connected to a redundant pair of T opspin 270/Cisco SFS 7008s. In an InfiniBand fabric that includes more than one T opsp.

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 opspin 270/Cisco SFS 7008 maintains correct time regardless of po wer conditions or connectivity . Latency The T opspin 270/Cisco SFS 7008 has port to port latency of less than 600ns.
