How to upload the software in the slave MPU of a running NE80E

Publication Date:  2012-07-27 Views:  41 Downloads:  0
Issue Description
 The scenario is the following: you have in a customer network a NE80E in service, having traffic and running with two MPU?s. Then one MPU becames to the faulty state and it is needed to replace it. You make a switchover so that the slave MPU could get the device management and  
 can continue working. Later a MPU spare is needed and the board arrives to the site. Usually the spare does not have the same software than the customer is  
 running in the network so it is needed to upload it to the board. If you do not have laboratory and you have to upload from the running NE80E when you connect to  
 the console port of the new MPU the system showes you you are connected to the slave MPU and you can not manage the upload process.
      
Alarm Information

Following this process we can success with the upload but it could be better to upload the software from the console port of the slave board.
DEAR APPROVER:
in the manual there is nothing said about upgrading a slave mpu in a running NE. it is just said how to upgrade from botroom but what I suggest is quite different so please take into account.
