Working inside the server with the power on

Use this information when working inside the server with the power on.

Attention

Static electricity that is released to internal server components when the server is powered-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.

You might have to have the server turned on while the cover is off, to look at light path diagnostics LEDs or replace hot swap components. Follow these guidelines when you work inside a server that is turned 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, that could fall into the server as you lean over it.
• Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the server.
