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 specications and/or part
numbers given.
Installation or replacement of most components require that power rst 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. This
step is necessary when removing or installing non hot-swap components or when replacing
a non-redundant power supply.
1. Use the operating system to power down the system.
2. After the system has completely shut-down, disconnect the AC power cord(s) from the
power strip or outlet. (If your system has more than one power supply, remove the AC
power cords from all power supply modules.)
3. Disconnect the power cord(s) from the power supply module(s).
3.2 Accessing the System
The SC504-203B features a removable top cover, which allows easy access to the inside of
the chassis.
Removing the Top Cover
1. Begin by removing power from the system as described in Section 3.1.
2. Remove the screws securing the cover to the chassis.
3. Slide the cover toward the rear of the chassis. See Figure 3.1.
4. Lift the cover from the chassis.
Warning: Except for short periods of time, do not operate the server without the cover in place.
The chassis cover must be in place to allow for proper airow and to prevent overheating.
