Removal and replacement procedures 41

Remove the SAS cage.

To replace the component, reverse the removal procedure.

System fans

The server supports redundant hot-plug fans to provide proper airflow to the system if a primary fan fails.

In the standard, non-redundant, configuration, fans 1, 2, and 3 cool the server.

For the redundant configuration, fans 4, 5, and 6 are added to back up the primary fans. This

configuration enables the server to continue operation in non-redundant mode, if a fan failure occurs. The

following rules apply:

• If one fan fails in non-redundant mode, the server shuts down.

• If one fan fails in redundant mode, the server converts to non-redundant mode.

• If two fans fail in redundant mode, the server shuts down.

For more information, see "Fan locations (on page 90)."

All fans are identical. This procedure can be used for any of the six fan positions.

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.
