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.
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:
v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts
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
that the component can be hot-swapped, which means that if the server and
operating system support hot-swap capability, you can remove or install the
component while the server is running. (Orange can also indicate touch points on
hot-swap components.) See the instructions for removing or installing a specific
hot-swap component for any additional procedures that you might have to
perform before you remove or install the component.

work properly. Leave approximately 50 mm (2.0 in.) of open space around the
front and rear of the server. Do not place objects in front of the fans. For proper
cooling and airflow, replace the left-side cover before you turn on the server.
Operating the server for extended periods of time (more than 30 minutes) with
the left-side cover removed might damage server components.
