Replacing a hot-swap fan

Your server comes with nine hot-swap fans: six internal and three external. The
internal fans consist of the front, center, and top rear fans. The front fans (1 and 2)
are located inside the server in front of the air baffle, the top rear fans (fans 3 and
4) are located inside the server at the rear of the air baffle, and the center fans
(fans 5 and 6) are located inside the server near the adapters. The external fans
(fans 7 through 9) are located on the outside of the server in front of the power
supplies. When a fan has failed or is operating slowly, the amber LED illuminates
on that fan. You do not need to turn off the power to the server to replace a
hot-swap fan.
Attention:
proper cooling. If a fan fails, replace it as soon as possible to maintain and ensure
proper cooling.
Complete the following steps to replace a hot-swap fan. The internal fans (front,
center, and top rear) are installed differently from the external fans (bottom rear).
