To perform an extension shelf on-demand software upgrade

Purpose

Perform this procedure to upgrade the device software on one or more extension shelves.

The following must be true before you attempt a device software upgrade.

  • You have an NFM-P user account with an administrator or network element software management scope of command role, or a scope of command role with write access to the mediation package.

  • The FTP or SFTP credentials are configured in the NE mediation policy.

CAUTION

Service Disruption

A device may require a firmware upgrade before a software upgrade.

To avoid a service outage, ensure that the device firmware version supports the software release. See the device software Release Notes for information about firmware and software compatibility, and about the firmware upgrade procedure.

Service Disruption

Nokia recommends that you open a physical console session on the NE that you need to upgrade so that you can monitor the upgrade and recover in the event of an upgrade failure.

Read the software upgrade information in the device documentation before you perform a software upgrade.

You cannot upgrade an NE to a chronologically older release, regardless of the release identifier; for example, the R1 revision of a release may predate the R9 revision of the previous release. See the NSP NFM-P Network Element Compatibility Guide for information about the supported device upgrade paths.

Note: Before you downgrade a device, you must unmanage and delete the device from the NFM-P. Contact Nokia technical support for information about device downgrades.

The NFM-P automatically creates software repositories for use with extension shelf upgrades. To manually create a software repository, see To create a software repository.
