Working inside the server with the power on
Attention:
Static electricity that is released to internal server components when the server is turned on might cause the server to
halt, which might result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist
strap or other grounding system when you work inside the server with the power on.
The server supports hot-swap devices and is designed to operate safely while it is turned on and the cover is
removed. Follow these guidelines when you work inside the server with the power on:
• Avoid wearing 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, necklaces, rings, and loose-fitting wrist watches.
• Remove items from your shirt pocket, such as pens and pencils. These items might fall into the server as
you lean over it.
• Avoid dropping any metallic objects into the server, such as paper clips, hairpins, and screws.
