SR870BN4 - Power Subsystem Supported Features

The SR870BN4 Model 0 comes with 1 power supply, which is sufficient for any configuration of processors, memory and I/O devices possible at 200V – 240V, but does not provide redundancy. A filler panel must be installed in systems using only 1 power supply

The SR870BN4 Model 1 comes with 2 power supplies, which is sufficient for any configuration of processors, memory and I/O devices possible at 200V – 240V and provides redundancy.

The DC to DC (D2D) converters needed for the maximum system configuration are as follows:

•Two 5V DC to DC converters (standard on Model 0 and Model 1)

•Five 2.5/3.3V DC to DC converter (standard on Model 0 and Model 1)
