Working inside the server with the power on

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.
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 a server that is
turned on:

components.
You have followed the cabling instructions that come with optional adapters.
You have replaced a failed fan within 48 hours.
You have replaced a hot-swap drive within 2 minutes of removal.
For redundant and hot-swappable power supply operation, the power supplies are
connected to 200-240 V ac.
Microprocessor sockets 1 - 4 each always contain either a heat-sink blank or a
microprocessor and heat sink.
CAUTION
Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts before
you work 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 might fall into the
server as you lean over it.
Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the
server.
