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 part
numbers given.
Remove power from the system before installing or replacing components. Refer to Section

non-redundant power supply.
1. Use the operating system to power down the system.
2. After the system has fully 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).
