Installing a hot-swap fan
For proper cooling, the server requires that all three fans be installed at all times.
Attention: To ensure proper server operation, if a fan fails, replace it immediately.
Have a replacement fan ready to install as soon as you remove the failed fan.
See “System-board internal connectors” on page 15 for the locations of the fan
connectors.
