xSeries 440:Installation Guide
Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before
working inside the server; do not wear cuff links while you are working inside the
server.
Do not allow your necktie or scarf to hang inside the server.
Remove jewelry, such as bracelets, rings, necklaces, and loose-fitting wrist
watches.
Remove items from your shirt pocket, such as pens or pencils, that could fall into
the server as you lean over it.
Take care to avoid dropping any metallic objects, such as paper clips, hair pins, or
screws, into the server.
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 damage it.
While the device is still in its static-protective package, touch it to an unpainted
metal part of the server for at least 2 seconds. This drains static electricity from
the package and from your body.
Remove the device from its package and install it directly into the server without
setting it down. If it is necessary to set down the device, place it back into its
static-protective package. Do not place the device on your server cover or on a
metal surface.
Take additional care when handling devices during cold weather. Heating reduces
indoor humidity and increases static electricity.
