Maintenance and Component Installation
This chapter provides instructions on installing and replacing main system components. To
prevent compatibility issues, only use components that match the specifications and/or part
numbers given.
Installation or replacement of most components require that power first be removed from the
system. Please follow the procedures given in each section.

3.1 Removing Power

Use the following procedure to ensure that power has been removed from the system.
1. Use the operating system to power down the system.
2. After the system has completely shut-down, disconnect the AC power cords from the
power strip or outlet.
3. Disconnect the power cords from the power supply modules.

3.2 Accessing the System

The chassis features a removable top cover for access to the internal components.
When performing service on components inside the system, remove the system from
the rack and place it on a work bench or desk. Do not service with the system extended
from the rack.
The CSE-825BTQC chassis features a removable top cover, which allows easy access to
the inside of the chassis.
Removing the Top Cover

2. Press the release tabs to remove the cover from the locked position. Press both tabs at
the same time.
