Chapter 1. General description 9
Two GX++ slots
Integrated:
– Service processor
– EnergyScale technology
– Hot-swap and redundant cooling
– Three USB ports and two system ports
– Two HMC ports and two SPCN ports
Redundant, 1925 watt AC hot-swap power supplies
1.4.3 Minimum features
Each system has a minimum feature set to be valid.
The minimum initial order must include a processor, processor activations, memory, a
power supply, a power cord (two power supplies and two power cords for the Power 740), one
HDD/SSD, a storage backplane, an operating system indicator, a cover set indicator and a
Language Group Specify.
If IBM i is the primary operating system (FC 2145), the initial order must also include one
additional HDD/SSD, a Mirrored System Disk Level Specify Code, and a System Console on
HMC Indicator. A DVD-RAM on every order is installed by default but may be deselected.
1.4.4 Power supply features
One 1925 watt AC power supply (FC 5532) is required for the Power 720. A second power
supply is optional. Two 1925 Watt A/C power supplies are required for the Power 740. 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 server continues 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.
1.4.5 Processor module features
Each processor module in the system houses a single POWER7+ processor chip. The
processor is either 4-core (Power 720 only), 6-core, or 8-core. The Power 720 supports one
processor module. The Power 740 supports a second processor module that must be
identical to the first.
The number of processor activation code features must be equal to the number of installed
processor cores.
Note: No internal HDD or SSD is required if FC 0837 (Boot from SAN) is selected. A Fibre
Channel or Fibre Channel over Ethernet (FCoE) adapter must be ordered if FC 0837 is
selected.
