Replacing an NPU1 C with an NPU1 D
4.2 Preparing the NE on Site
4.2.1 Starting the Local FTP Server
To start the local FTP server:
1. Access the NE locally and start MINI-LINK Craft by following the instructions
in Accessing a Network Element, Reference [1].
2. On the Tools menu, click FTP Server.
3. On the FTP Server page, under Starting and Stopping, click Start to
start the FTP server.
4.2.2 Verifying the Software Upgrade Preferences
To verify the software upgrade preferences:
1. In MINI-LINK Craft, in the Management Tree, right-click the NE.
2. Point to Tools, Software Upgrade, and click Preferences.
3. On the Preferences page, make sure Version Control is enabled. If
Version Control is disabled, it is recommended to perform an upgrade of
the SBL to enable Version Control before replacing the HW. See Section
4.2.3 on page 7 for more information on SBL upgrade.
Version Control checks if load modules comply to the active SBL. If
necessary, load modules are automatically upgraded or downgraded to
comply with the active SBL.
4.2.3 Upgrading the SBL
If an SBL upgrade is required, upgrade the SBL by following the instructions in
Upgrading or Downgrading a SW Baseline, Reference [11].
4.3 Replacing the Hardware
Note: Before performing the replacement, make sure that the required
configuration file is on the local FTP server, and that the required SBL
with Version Control enabled is running on the NE.
Make sure the local FTP server has been started as described in
Section 4.2.1 on page 7.
This section describes how to replace the hardware and how to move licenses
