Part number 8006715,A76006-006

The RPS500 power supply cage can support up to two TPW 500W SSI power supply modules in a 1+1 configuration or a non-redundant single module configuration (1+0). The power supply cage is capable of supporting hot swapping of power supply modules in a 1+1 configuration. The cage incorporates dual AC inputs with two electromagnetic interference (EMI) filters.

The power supply cage contains a microcontroller to monitor the status of the modules and provide control functions for the cage. The microcontroller is configured as a slave device on the SMBus. The status of the module and cage signals are available via the SMBus interface. The SMBus is also connected to each power module. The microcontroller is powered by 5-volt (V) standby and is connected to the ground on the power share board. The microcontroller makes use of the watchdog timer to reset the device in case the controller locks up.

The power supply cage contains a 2-kilobyte (KB) EEPROM device that contains FRU data for the cage according to the IPMI specification. Each separate output is given a different number for identification purposes.
