1.5.4 Power supply features
Two system AC power supplies (FC 5532) are required for each system enclosure. The
second power supply provides redundant power for enhanced system availability. To provide
full redundancy, the two power supplies must be connected to separate power distribution
units (PDUs).
The system will continue to function with one working power supply. A failed power supply can
be hot-swapped but must remain in the system until the replacement power supply is
available for exchange.
The Power 750 and the Power 760 require 200-240 V AC for all configurations.
1.5.5 Processor card features
The Power 750 and Power 760 systems contain a processor planar board (FC EPT1) that has
the following sockets:
Four processor sockets
Eight memory riser sockets (two per processor module) with eight DIMM sockets per riser
Five power regulator sockets (one regulator socket is preinstalled on the planar)
The processor planar is populated with one, two, three, or four processor modules. The
processor modules can be installed in field but must be installed by an IBM customer
engineer.
The Power 750 has two types of processor cards:
FC EPT8 offering 8-core POWER7+ processor card at 3.5 GHz
FC EPT7 offering 8-core POWER7+ processor card at 4.0 GHz
The Power 760 has two types of processor cards:
FC EPT5 offering 12-core POWER7+ processor card at 3.1 GHz
FC EPT6 offering 12-core POWER7+ processor card at 3.4 GHz
