► Redundant, 1725 watt ac hot-swap power supplies<br />
1.4.3 Minimum features<br />
Each system has a minimum feature set in order to be valid.<br />
The minimum initial order must include a processor, processor activations, memory, a<br />
power supply, a power cord (two power supplies and two power cords for the Power 740), one<br />
HDD/SSD, a storage backplane, an operating system indicator, and a Language<br />
Group Specify.<br />
If <strong>IBM</strong> i is the Primary Operating System (#2145), the initial order must also include one<br />
additional HDD/SSD, a Mirrored System Disk Level Specify Code, and a System Console on<br />
HMC Indicator. A DVD is defaulted on every order but can be de-selected. A DVD-ROM or<br />
DVD-RAM must be accessible by the system.<br />
Note: If AIX, <strong>IBM</strong> i, or Linux is the primary operating system, no internal HDD or SSD is<br />
required if feature #0837 (Boot from SAN) is selected. A Fibre Channel or FCoE adapter<br />
must be ordered if #0837 is selected.<br />
1.4.4 Power supply features<br />
One system 1725 watt ac power supply (#5603) is required for the Power 720. A second<br />
power supply is optional. Two system 1725 watt ac power supplies (#5603) are required for<br />
the Power 740. The second power supply provides redundant power for enhanced system<br />
availability. To provide full redundancy, the two power supplies must be connected to separate<br />
PDUs.<br />
The server will continue to function with one working power supply. A failed power supply<br />
can be hot swapped but must remain in the system until the replacement power supply is<br />
available for exchange.<br />
1.4.5 Processor module features<br />
Each processor module in the system houses a single POWER7 processor chip.<br />
The processor has either 4 cores, 6 cores, or 8 cores. The Power 720 supports one processor<br />
module. The Power 740 supports a second processor module that must be identical to the<br />
first.<br />
The amount of processor activation code features must be equal to the amount of installed<br />
processor cores.<br />
