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 specications 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
Removing power from the system 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 cords from all
power supply modules.
3.2 Accessing the System
The 7089P-TR4T is a modular system with the motherboards, hard drives, fans and power
supplies all accessible for servicing without the need to open the chassis.
Please refer to the relevant sections in this chapter for the correct procedures to use when
servicing any of these subsystems.
