Before powering off the MPU, you need to run the 

display device

 command to view

the status of the MPU. If the MPU is the master MPU, perform the master/slave
switchover first.

3.

Run the 

quit

 command to return to the system view

4.

Run the 

power

slot

 

slot-id-mpu

 command to power off the slave MPU.

NOTE

If there is no terminal on the deployment site, you can power off the slave MPU by pressing the OFL
button. The OFL button is on the upper part of the panel for the slave MPU. Press and hold the button
for six seconds till the OFL indicator lights. This indicates that the slave MPU is powered off.
