UMPT Replacement Implementation

2.1 Prerequisites  Confirm the UMPT board was faulty, and a new board has been prepared.  Prepare the MBTS Software, save inside local PC for LMT local upgrading or upload to OSS server  Associated personnel have gained permission to access the site and have obtained the required keys.

2.2 Process for UMPT Board Replacement The UMPT board replacement progress, except the local UMPT new board replacing with the old board, the others steps can be implemented both locally and remotely. In T project, some regions did not enable the DHCP function, so only can use the local way.
