Working inside the server with the power onThe server supports hot-swap devices and is designed to operate safely while it isturned on and the cover is removed. Follow these guidelines when you work insidea server that is turned on:v Avoid wearing loose-fitting clothing on your forearms.

Movement can cause static electricity to build up aroundyou.v Handle the device carefully, holding it by its edges or its frame.v Do not touch solder joints, pins, or exposed circuitry.v Do not leave the device where others can handle and damage it.v While the device is still in its static-protective package, touch it to an unpaintedmetal part of the server for at least 2 seconds. This drains static electricity fromthe package and from your body.v Remove the device from its package and install it directly into the server withoutsetting down the device. If it is necessary to set down the device, put it back intoits static-protective package. Do not place the device on the server cover or on ametal surface.v Take additional care when handling devices during cold weather. Heating reducesindoor humidity and increases static electricity.12 xSeries 236 Type 8841: Hardware Maintenance Manual and Troubleshooting Guide
