IBM x Series 200 Working inside the server with the power on, System reliability considerations

•Before you place the server in an upright position, rotate the two front feet a quarter turn away from the server. For complete details, see “Moving the stabilizing feet” on page 40.

•Make sure that you have an adequate number of properly grounded electrical outlets for the server, monitor, and any other options that you intend to install.

•Back up all important data before you make changes to disk drives.

•For a list of supported options for the 200, refer to http://www.ibm.com/pc/us/compat on the World Wide Web.

Working inside the server with the power on

The server is designed with safety in mind. Follow these guidelines when you work inside a server that is turned on:

•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 to hang inside the server.

•Remove jewelry, such as bracelets, necklaces, rings, 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.

•Avoid dropping any metallic objects, such as paper clips, hair pins, or screws, into the server.

System reliability considerations

To help ensure proper cooling and system reliability, make sure that:

•Each of the drive bays either has a drive, or a filler panel and electromagnetic compatibility (EMC) shield installed.

•There is space around the server to allow the server cooling system to work properly. Leave about 127 mm (5 in.) of space around the front and rear of the server.

•Cables for optional adapters are routed according to the instructions that are provided with the adapters.

•A failed fan is replaced within 1 hour.

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 bag 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.
