The six fan modules are located at the front of the chassis and provide cooling for the three motherboard cooling zones (for more information, see Cooling Subsystem). The fans are hot-serviceable and accessible by partially extending the server from the rack. You do not have to remove the server cover to service the fan modules.
Caution - Server shutdown or component damage due to over-temperature condition. Fan modules provide system cooling. If a fan module fails, replace it as soon as possible. When you remove one of the fans in the back row, you must replace it within 30 seconds to prevent overheating of the server. |
The functions of the fan module status indicators is described below.
The following indicators are lit when a fan module fault is detected:
Front and back Service Action Required indicators. See Server Front Panel Features and Server Back Panel Features for locations of system indicators.
Fan module Service Action Required indicator on the faulty fan module.
Over Temperature Warning LED. This indicator might also light if a fan fault causes an unacceptable increase in system operating temperature.
Each fan module contains indicators that are visible from the top of the server.
Green indicator. The system is powered on and the fan module is functioning correctly.
Amber indicator. The fan module is faulty.
The server front and back panel Service Action Required indicators are also lit if the system detects a fan module fault.
