Installing/Removing Power Supplies
You can replace power supplies without shutting down power to the Cajun P880. However, you must turn off the power to the power supply you are replacing.
CAUTION
Each power supply powers approximately nine I/O modules. You need a minimum of two power supplies if you have more than 10 modules in the chassis. It takes two power supplies to power a full chassis. Using three power supplies ensures that the system has redundant power capabilities.
Use Table 1 for the precise power values:
