Introduction; Handling Precautions - Fujitsu 5000 Series User Manual

1 Introduction

The features and performance of your PC can be upgraded by installing options. This section describes
the types of internal options that can be installed in the PC and explains how to remove the upper
cover and front panel in preparation for installing the internal options.

Handling precautions

Note the following when installing internal options:
- Before starting operation, switch off the PC and all connected peripherals and unplug power
cords from the AC outlets.
- Immediately after the PC is turned off, internal components and units of the PC are hot. When
installing and removing internal options, turn off the power and allow the PC to cool down for
about 10 minutes before starting operation.
- Do not disassemble the power supply unit (a box-shaped device inside the PC).
- Do not damage or remodel internal cables or units.
- Because internal options are PC boards with exposed soldered sections that may be damaged
by a static electrical charge, discharge any accumulated static electricity before handling.
- Secure the board by the metal bracket portions or an edge of the PC board such that the surface
of the PC board and the soldered sections are not handled.
- Installation and disassembly of options other than Fujitsu brand products void the warranty.
