Hot-plug fans
CAUTION: To avoid damage to the equipment, do not operate the server for extended periods of time if
the server does not have the optimal number of fans installed. Although the server might boot, do not
operate the server without the required fans installed and operating.
Fan bay 1
Fan
The loss of a single fan rotor (one standard fan) causes loss of redundancy. The loss of two fan rotors (two
standard fans or one high performance fan) causes the server to initiate a shutdown.
High-performance fans are required for some configurations. They are also required for ASHRAE-compliant
configurations. For more information on ASHRAE-compliant configurations, contact customer support.
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 during the following temperature-
related scenarios:
•
At POST and in the OS, iLO performs an orderly shutdown if a cautionary temperature level is detected. If
the server hardware detects a critical temperature level before an orderly shutdown occurs, the server
performs an immediate shutdown.
•
When the Thermal Shutdown feature is disabled in the BIOS/Platform Configuration (RBSU), iLO does not
perform an orderly shutdown when a cautionary temperature level is detected. Disabling this feature does
not disable the server hardware from performing an immediate shutdown when a critical temperature level
is detected.
CAUTION: A thermal event can damage server components when the Thermal Shutdown feature is
disabled in the BIOS/Platform Configuration (RBSU).
Basic Drive LED definitions
The Basic drive carrier has the following LEDs:
•
Amber/blue LED—Managed by the drive backplane in conjunction with the storage controller and is used
to indicate drive status.
•
Green LED—Managed by the drive itself and indicates the drive activity.
