the server. Operating the server for extended periods of time (more than 30 minutes) with the server
cover removed might damage server components.
• Properly route the cables. For some options, such as PCI cards, follow the cabling instructions that come
with the options in addition to the instructions in this manual.
• Make sure that you replace a failing fan within 48 hours.
• When replacing a hot-swap drive, install the new hot-swap drive within two minutes of removal.
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.
Removing the server cover
Attention:
Do not open your server or attempt any repair before reading and understanding the “Safety information”
on page iii and “Guidelines” on page 35.
This section provides instructions on how to remove the server cover.
Attention:
For proper cooling and airflow, install the server cover before turning on the server. Operating the
server for more than 30 minutes with the server cover removed might damage server components.
To remove the server cover, do the following:
1. Remove all media from the drives. Then, turn off all attached devices and the server.
2. Disconnect all power cords from electrical outlets.
3. Disconnect the power cord(s), Input/Output (I/O) cables, and all other cables that are connected to
the server.
