v When the air-baffle assembly is installed in the server, the air-baffle cover is always closed. v Microprocessor socket 2 always contains either a microprocessor baffle or a microprocessor. Working inside the server with the power on Your server supports hot-plug, hot-add, and hot-swap devices and is designed to operate safely while turned on with the cover removed. Follow these guidelines when you work inside a server that is turned on: v 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. v Do not allow your necktie or scarf to hang inside the server. v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist watches. v Remove items from your shirt pocket (such as pens or pencils) that could fall into the server as you lean over it. v Avoid dropping any metallic objects, such as paper clips, hair pins, or screws, into the server. 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 packages until you are ready to install them. To reduce the possibility of electrostatic discharge, observe the following precautions: v Limit your movement. Movement can cause static electricity to build up around you. v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed printed circuitry. v Do not leave the device where others can handle and possibly damage the device. v 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.) v Remove the device from its package and install it directly into the server without setting down the device. If it is necessary to set down the device, place it back into its static-protective package. Do not place the device on the server cover or on a metal surface. v Take additional care when handling devices during cold weather because heating reduces indoor humidity and increases static electricity. Major components of the xSeries 235 Type 8671 server The orange color on components and labels in your server identifies hot-swap or hot-plug components. You can install or remove hot-swap or hot-plug components while the system is running, provided that your system is configured to support this function. 46 xSeries 235 Type 8671: Hardware Maintenance Manual and Troubleshooting Guide
