7210 SAS-D and 7210 SAS-D ETR variant with 128MB flash

Description

The 7210 SAS-D chassis with 128MB flash has a fan to help in circulating the air inside the chassis. It does not provide for cooling. This command allows the operator to control the operation of the fan.

Operators can choose to either switch on or off the fan permanently or allow the system control the operation of the fan by setting the value to auto.

In auto mode, software controls the operation of the fan. It switches the fan on, if the system defined temperature threshold is exceeded and switches it off when temperature falls back to normal. It also ensures that fan is not switched on and off more than once in 30 minutes.
