Upgrading the SX Firmware
You can display the version of the firmware currently running on the SX,
upgrade the firmware to a later version, and display a history of firmware
upgrades.
Note: Dominion SX can only be upgraded, while downgrade is not
possible.
Display the Current Firmware Version
To display the current version of firmware running on an SX unit, choose
Maintenance > Firmware Version. The Firmware Version page opens,
displaying the Firmware Version, RSC, Kernel, and PMON.
Upgrade the Firmware
Before you perform a firmware upgrade, you must:
1. Download the upgrades file(s), which are in WinZip format onto a
folder on the local FTP server.
2. Obtain the IP address of the FTP server.
3. Obtain the file path to the upgrade file(s). This is the path to the
extracted upgrade files, for example, cert_pact.tgz, on the FTP
server.
4. Obtain a user account (optional) if “anonymous” access to the FTP
server is not supported.
The Firmware Upgrade feature allows you to upgrade the Dominion
SX unit's firmware to a newer version. These upgrades preserve
user-defined settings. You do not need to re-configure the unit after
the upgrade is complete.
Important: During an upgrade procedure, do not attempt to access
any unit features or functions, including, but not limited to, Reset
and Exit. Interrupting the upgrade procedure can cause memory
corruption and render the unit non-functional. Such an action may
void your warranty or service contract, and in such a case unit
repair/replacement costs are solely the responsibility of the user.
