Information in this document applies to any platform.
Purpose
This document describes the fan / tray redundancy, behavior of systems in case of fan / fantray failure and the fan speed control depending on inlet temperature.
Scope
Details
This section describes the environment and failure behavior.
The showenvironment command is used to display various temperatures and fan speeds.
XSCF> showenvironment
XSCF> showenvironment temp
XSCF> showenvironment Fan
The showaltitude command is used to display the altitude setting.
XSCF> showaltitude
Note: In the following tables, threshold temperatures are temperatures where an action is taken, the sign ">" means greater or equal and the sign "<" means smaller or equal in this context.
Common specification for M10-1, M10-4, M10-4S systems have a single inlet temperature sensor on the Operator Panel (OPNL)

Full speed (level5) is never set based on temperature, it is only used in case of a fan failure in the cooling group.
M10-1
In addition to inlet temperature sensor, M10-1 systems have the onboard temperature sensor on the Motherboard (MBU). The CPU chip and the DIMM have temperature sensors.
Fans on M10-1 systems have 5 speeds: level 1 - level 5
Fan failure behavior
- Failure of a FAN40_A, and if the other FAN40_A on the platform is operational, then this other fan's speed is raised to full speed (level 5).
- If the failure is due to a failure of a fan in a PSU, and if all the other fans in the PSUs of the cooling group are operational, then the other fan of this PSU has its speed raised to full speed and the speed of all other fans on the platform is raised to full speed.
- If the second fan in a cooling group becomes non-operational, then XSCF shuts down the Ppar and powers off the platform.

M10-4 & M10-4S
In addition to inlet temperature sensor, M10-4 & M10-4S systems have the onboard temperature sensor on the Motherboard (MBU). The CPU chip and the DIMM have temperature sensors.
Fans on M10-4 & M10-4S systems have 5 speeds: level 1 .. level 5
Fan failure behavior
- Failure of a FANUQ_A, and if the other FANUQ_A on the platform is operational,then this other fan's speed is raised to full speed (level 5).
- If the failure is due to a failure of a fan in a PSU, and if all the other fans in the PSUs of the cooling group are operational, then the other fan of this PSU has its speed raised to full speed and the speed of all other fans on the platform is raised to full speed.
- If the second fan in a cooling group becomes non-operational, then XSCF shuts down thePpar and powers off the platform.

Improvements to the cooling requirements have been introduced in XCP2260 to lessen system noise by reducing fan speed.
This reduction is dependent on the environment and operating load.
