Peripheral Power Supply

In the front of the system is a slot for an optional auxiliary peripheral power supply (PPS). The PPS, also known as PPS1 to the system software, supplies redundant current for the peripheral devices.

If an auxiliary peripheral power supply is not installed, a thermal protection module must be installed in the PPS slot.

A thermal protection module or a power supply is required in the PPS1 slot to ensure maximum operating temperature is not exceeded.
