Replacing a hot-swap fan
Your server comes with six hot-swap fans (two front fans in connector J50, two
center fans in connector J18, and two rear fans in connector J25). The two largest
fans (in connector J50) are also known as blowers. You do not need to turn off the
power to the server to replace a hot-swap fan.
Attention: To help ensure proper cooling, if a fan fails, replace it within 48 hours.
The following illustration shows how to replace hot-swap fans.
