Fan redundancy support
Fan redundancy support
The number of fans installed in the server determines fan redundancy. When redundant fan mode is enabled, hot-plug fan operation is
supported.
In this server, fan operation can either be one of the following:
Hot-plug—A failed fan can be replaced without powering down the server
Non-hot-plug—To replace a failed fan, the user must either:
Keep the server powered on and complete the fan replacement within 60 seconds of opening the access panel, or
Power down and disconnect all power from the server before removing the access panel for fan replacement.
Fan mode behavior
Fan mode behavior
In nonredundant fan mode, a fan failure or a missing fan causes:
The system Health LED to flash amber.
The operating system to gracefully shut down.
In redundant fan mode:
A fan failure or a missing fan will switch the system to nonredundant fan mode.
This change is indicated by the Health LED flashing amber. The system continues to operate normally in this mode.
A second fan failure or a missing fan causes the operating system to gracefully shut down.
