Downloaded Version
The version, if any, that has been downloaded from the server but not yet
installed. Upon installation, this version will become the Installed Version.
Reset Type
The level of reset required by the component in order for the Installed
Version to become the Active Version. A cold (hard) reset powers down
and powers back up the component. A warm (soft) reset simply reboots
the software or firmware in the component.
Software Upgrade Overview
The PTP 850 software installation process includes the following steps:
1.
Download
– The files required for the installation or upgrade are downloaded from a remote server.
2.
Installation
– The downloaded software and firmware files are installed in all modules and components of the
PTP 850 that are currently running an older version.
3.
Reset
– The PTP 850 is restarted in order to boot the new software and firmware versions.
Software and firmware releases are provided in a single bundle that includes software and firmware for all
components in the system. When you download a software bundle, the system verifies the validity of the bundle.
The system also compares the files in the bundle to the files currently installed in the PTP 850 and its components,
so that only files that need to be updated are actually downloaded. A message is displayed for each file that is
actually downloaded.
Note
When downloading an older version, all files in the bundle may be downloaded, including files that
are already installed.
Software bundles can be downloaded via HTTP, HTTPS, FTP or SFTP. After the software download is complete, you
can initiate the installation.
Note
Before performing a software upgrade, it is important to verify that the system date and time are
correct. See
Setting the Time and Date (Optional)
When upgrading a node with unit protection, upgrade the standby unit first, followed by the active
unit.
Downloading and Installing Software
You can download software using HTTP, HTTPS, FTP or SFTP.
When downloading software via HTTPS or HTTPS, the PTP 850E functions as the server, and you can download the
software directly to the PTP 850E unit.
