UATool Usage Scenario

The UATool must be used to upgrade the ME60. The UATool can be used in three upgrade scenarios. Huawei recommends the first two scenarios. The third scenario, on-site upgrade, can be used if necessary. The three scenarios are described below:

  Remote upgrade with nearby support

Software commissioning engineers remotely upgrade the ME60 from the network management center. Spare part provisioners wait near the site and are ready to deliver spare parts to the site quickly. Huawei recommends this scenario in the following situations:

−    The project is at the site deployment stage, and there are no stringent time requirements for replacing spare parts.

−    The spare part provisioning site is close to the upgrade site with favorable traffic and road conditions so that spare parts can be installed within the required time frame.

−    There are backup planes or links on the customer's network, and customer requirements allow enough time to install spare parts.

  Remote upgrade with on-site support

Software commissioning engineers remotely upgrade the ME60 from the network management center. Spare part provisioners wait on site. Huawei recommends this scenario if spare parts cannot be delivered to the site within the required time frame.

  On-site upgrade

Software commissioning engineers upgrade the ME60 on site. Spare parts are also available on site. This scenario can be used when only one site is being upgraded.

Huawei recommends that the upgrade is performed using the UATool. The UATool can automatically compare pre-upgrade services and post-upgrade services. This prevents operator errors during the upgrade and decreases upgrade risks.

In all the three scenarios, software commissioning engineers must be Huawei engineers with a good command of the ME60 upgrade procedures. The personnel providing and replacing parts (who can be engineers from Huawei partners or customer staff) must be able to correctly identify product models and replace boards.

The three scenarios described above are examples of typical upgrade situations. Engineers can flexibly determine the way the upgrade is performed based on the real-world situation.

The ME60 plays an important role on a network. Ensure that spare parts are available when using the UATool to upgrade the ME60-X3
