IBM 343 manual Handling Static-sensitive Devices, Removing and Installing the Top Cover

Handling Static-sensitive Devices

Attention: Static electricity can damage electronic devices and your system. To avoid damage, keep static-sensitive devices in their static-protective package until you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following precautions:

•Limit your movement. Movement can cause static electricity to build up around you.

•Handle the device carefully, holding it by its edges or its frame.

•Do not touch solder joints, pins, or exposed printed circuitry.

•Do not leave the device where others can handle and possibly damage the device.

•While the device is still in its anti-static package, touch it to an unpainted metal part of the system unit for at least two seconds. (This drains static electricity from the package and from your body.)

•Remove the device from its package and install it directly into your system unit without setting it down. If it is necessary to set the device down, place it in its static-protective package. Do not place the device on your system unit cover or on a metal table.

•Take additional care when handling devices during cold weather because heating reduces indoor humidity and increases static electricity.

Removing and Installing the Top Cover

Note

For proper cooling and airflow, do not operate the server with the cover removed. Always reinstall the cover before turning the server on.

The server comes with a removable Top Cover. Removal of this cover is necessary when installing or removing many components. You do not have to remove the Top Cover when removing or installing power supplies or hard drives.

Statement 15

CAUTION

Make sure that the rack is secured properly to avoid tipping when the server unit is extended.

Note

Only use a screwdriver tip to push in the lock tabs on the rack slides. A pinch hazard exists if fingers are used for this purpose.
