Viewing Fan Sensors

SUMMARY STEPS

  1. Server# scope sensor
  2. Server /sensor # show fan [detail]
  3. Server /sensor # show fan-pwm
  4. Server /sensor # show fan-pwm [detail

DETAILED STEPS

  Command or Action Purpose

Step 1

Server# scope sensor

Enters sensor command mode.

Step 2

Server /sensor # show fan [detail]

Displays fan sensor statistics for the server.

Step 3

Server /sensor # show fan-pwm

Displays the PWM %.

Beginning with the release 4.3(5.240021)​, Cisco IMC displays an additional sensor property for the fan - Pulse Width Modulation (PWM).

PWM is the absolute measure of the fan on and off duration to control the speed. The ratio of on time compared to off time is known as Duty cycle.

Step 4

Server /sensor # show fan-pwm [detail

Displays the PWM % in detail.

Setting Dynamic Front Panel Temperature Threshold

Before you begin

Log in as a user with admin privileges.

Procedure

  Command or Action Purpose

Step 1

server # scope sensor

Enters sensor command mode

Step 2

server /sensor # set fp-critical-temp upper critical temperature threshold value

Sets the upper critical temperature threshold. The valid range is between 8 and 50.

Step 3

server /sensor * # commit

Commits the change in temperature threshold value.

Example

This example shows how to set the dynamic front panel temperature threshold: 


Server # scope sensor
Valid value for "fp-critical-temp" is from 8 to 50
