Before you start uploading firmware, please read the following information to become familiar with the process.
It is a good practice to first check the System Inventory and make a note of the current firmware installed in the modules for reference. After installation, you can then check the inventory to ensure the correct version is installed in each module. And before you start uploading firmware, you may want to open a Telnet session to directly monitor the progress.
Checking System Inventory
The screen provides a list of all installed modules in the currently connected SSU-2000. It lists the serial number, hardware and software part numbers, and the hardware and software revision numbers.
Opening A Telnet Session
Opening a Telnet session to the SSU-2000 and observing the command responses is a good way to monitor the firmware upload and installation progress. You can automatically open a Telnet session to the currently connected network element by selecting the Tools menu item and clicking Telnet. See Session for details.
Uploading Firmware
In a system with redundant Clock and Output modules, the upgrade process automatically provides uninterrupted service. In a system with non-redundant Clock or Output modules, any non-redundant outputs are temporarily interrupted. Most firmware upgrades do not result in a loss of module or system configuration, but there are exceptions. Contact Symmetricom Global Services (SGS) to determine the impact of the upgrade process on the retention of system configuration.
You normally load software in one of the following instances:
Symmetricom releases updated software
You want to add a software-based function (SNMP or NTP) to your current configuration
Software in your shelf has become corrupt
Contact SGS for information on obtaining firmware source files.
