There are three brackets supplied for the shelf installation: shelf
pieces and one brace for the rear of the rack. To install the shelf:
1. Install the mounting shelf. Attach the two side shelf pieces to the
rack. Make sure that each hole on the mounting bracket lines up
with a hole on the rail. This ensures proper vertical placement in
the rack. Do not completely tighten the screws.
2. Attach the brace piece to the shelf pieces by inserting the
attached stud into the holes on the shelf pieces and tightening
the nuts (Figure 2).
3. Check the rack and shelf to ensure they are square before
installing the chassis. Tighten all screws before installing the

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 Table1 for the precise power values:
Table 1. Power Values for System Devices
Device Power Added/Used
Power Supply + 600 W (1 power supply)

Installing/Removing Fan Assemblies
The Cajun P880 contains two fan assemblies:
■ One large chassis fan tray containing ten fans to cool the logic
section of the system.
■ One smaller rear fan tray containing four fans, mounted on
the lower rear panel to cool the switch elements.
Both fan assemblies are hot-swappable and contain fan management
circuitry to:
■ Provides power to the fans
■ Supplies reduced voltage to the fans, for reduced speed
operation
■ Provides the Fan OK and present status signal to the CPU
■ Forces full fan speed operation, in the event of a fan failure
■ Accepts a control signal from the CPU, to force full fan speed
in the event of an over-temperature condition.
