Installing/Removing Power Supplies
CAUTION
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.
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:
Installing the Power Supply
The Cajun P880 can contain up to three power supplies. This
procedure describes how to add or replace the power supplies in the
unit.
1. Carefully remove the supply and power cord from the shipping
box, leaving the supply in its anti-static wrapping.
