System expansions and repairs

We recommend printing out the relevant sections of this chapter prior to installation

as the device for installing/removing hardware components needs to be switched off.

The following illustrations may differ from your device, depending on its configuration and features.

If you have received any further documents with your device, you should read these through carefully.

Please note the following instructions before installing/removing system components:

■ The device must be switched off when installing/removing components and it must

not be in power-saving mode.

■ Disconnect the mains plug before opening the device.

■ After unplugging the mains plug, discharge the remaining voltage by pressing the

activation button.

■ Remove all externally connected cables.

■ Take care not to pinch any cables when installing/removing components.

■ Please ensure that the installed components that might heat up intensely during

operation do not exceed the permitted operating temperature.

During a system expansion or a hardware upgrade, it is possible that the BIOS must

be updated. You can find more information in the technical information provided for

your device.

Information on the installation and removal of components

Please pay attention to the locking mechanism (indentations and centring pins) when installing hardware components.

Note that some components on the mainboard may be very hot if the device was in use shortly before the case was removed.

Utmost care is required during installation and removal to avoid damaging components.

Never use items with sharp edges (screwdrivers) to lever them out.

Parts with Electrostatic Sensitive Devices (ESD) can be identified by a corresponding label.

When dealing with boards with ESDs, the following points must always be observed:

■ Always ensure there is a static discharge (e.g. by touching a grounded object) prior to commencing

with the work.

■ The devices and tools being used must not be statically charged.

■ Only touch the components along the edges or on the areas marked in green (contact points).

■ Contacts and electronic components must not touch when handling components equipped with ESD

protection.
