Removal and replacement procedures 40
To replace the component, reverse the removal procedure.
Hot-plug fan
The server supports variable fan speeds. The fans operate at minimum speed until a temperature change
requires a fan speed increase to cool the server.
The server shuts down in the following temperature-related scenarios:
•
At POST:
o
The BIOS suspends the server for 5 minutes if it detects a cautionary temperature level. If the
cautionary temperature level is still detected after 5 minutes, the BIOS performs an orderly shutdown
and enters Standby mode.
o
The BIOS performs an orderly shutdown if two or more fans have failed.
o
The server performs an immediate shutdown if it detects a critical temperature level.
IMPORTANT: An immediate shutdown is a hardware-controlled function and it overrides any
firmware or software actions.
•
In the operating system:
o
The Health Driver performs an orderly shutdown if it detects a cautionary temperature level. If the
server detects a critical temperature level before the orderly shutdown occurs, the server performs an
immediate shutdown. Additionally, the Health Driver performs an orderly shutdown if more than
one fan is failed or removed.
o
When Thermal Shutdown is disabled in RBSU, the server performs an immediate shutdown if it
detects a critical temperature level.
IMPORTANT: An immediate shutdown is a hardware-controlled function and it overrides any
firmware or software actions.
