Replacing hot-swap fans The server comes with four hot-swap fans: two front fans (fans 1 and 2), and two center fans (fans 3 and 4). You do not have to turn off the power to the server to replace a hot-swap fan. If the server is equipped with the IBM xSeries 670-Watt Hot-swap Power-Supply option, two rear fans (fans 5 and 6) must also be installed on the server. For information on replacing these fans or installing this option, see "Replacing a rear fan (5 or 6)" on page 20 or "Installing the 670-Watt hot-swap power-supply option" on page 21. 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.
