PMU02C1 Upgrade 

You can upgrade the PMU02C1 remotely on the 

Upgrade

 page shown in Figure 6-17 

To upgrade the PMU module, perform the following steps: 

Step 1

 

Before upgrade, obtain the name, size, and save path of the upgrade file. 

Step 2

 

On the

 Upgrade

 page, click 

Browse

 and then select the *.hex file. 

Step 3

 

Click 

Send

. 

----End 

You can learn about the upgrade result in the following ways: 

 

View the message displayed during the upgrade. 

 

View the records in the log history. 

 

Check whether the version of 

Power Manufacturer

 is the target version of the upgrade. 

 

The upgrade takes about 30 minutes. Do not perform any operations on the Web UI during the upgrade. 
Regardless of success or failure, the PMU02C1 will be restarted automatically. If the upgrade fails, you 
need to repeat Step 2 till the upgrade succeeds.
