Installing options

• You do not need to turn off the server to install or replace hot-swap power
supplies, hot-swap drives, hot-swap fans, or hot-plug PCI adapters.
• The orange color on components and labels in the server identifies hot-swap or
hot-plug components. This means that you can install or remove the component
while the system is running, provided that the system is configured to support
this function.
• The blue color on components and labels identifies touch points where you can
grip a component, move a latch, and so on.
• Make sure that you have an adequate number of properly grounded electrical
outlets for the server, monitor, and any other options that you intend to install.
• Back up all important data before you make changes to disk drives.
• For a list of supported options for the Netfinity 7600, refer to

Working inside the server with the power on
The server is designed with features that make it highly available. These features are
hot-add and hot-plug devices. Hot-plug devices allow you to replace the device
without turning off the server. Hot-add devices allow you to add an identical device
without turning off the server. In the past you would need to turn off the server and
disconnect power to perform these operations. With the hot-plug features, you can
remove the top cover of the server with the power on.
The server supports hot plug, hot add, and hot swap devices and is designed to
operate safely while turned on with the top cover removed. The server is designed to
protect you and the server. Follow these guidelines when you work inside a server
that is turned on:
• Avoid 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 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 or pencils) that could fall into
the server as you lean over it.
• Take care to avoid dropping any metallic objects, such as paper clips, hair pins, or
screws, into the server.
