Removing and Replacing Hot-Swap and Hot-Plug Devices
The server has hard drives that are hot-pluggable and power supplies and fans that are
hot-swappable. This section explains how to replace the following devices while the server is
running:
• System fans
• Power supplies
• Hard drives
There is a significant difference between the terms hot-swap and hot-plug:
• Hot swapping happens at the device level. A hot-swappable device manages insertion or
removal on its own without assistance from operating system commands.
• Hot-plugging allows you to replace a defective component in a high-availability server while
it is running. However, hot-plugging might require interaction with the operating server to
allow the removal and replacement of a hot-plug device.
Removing and Replacing Server Fans
Four server fans keep the server cool. The server fans are hot-swappable, enabling you to replace
a fan while the server is running.
CAUTION: When the server is running, you must replace the top metal cover to prevent
components from overheating. If the top metal cover is not replaced within 30 minutes, the server
automatically shuts down.
If the server shuts down, replace the top metal cover before you restart the server.
Removing a Server Fan
1. Extend the server from the rack. See “Extending the Server from the Rack” (page 42) .
2. Remove the top metal cover. See “Removing the Top Metal Cover” (page 43) .
