Upgrading the Firmware

New firmware versions typically provide:

• Additional functionality
• Enhancements to the existing feature set
• Defect corrections

To verify the current firmware version, refer to the Current Version field of the Firmware Maintenance section in the System ▶Maintenance ▶Firmware page.

You can upgrade the firmware by downloading the firmware file directly from your computer or network. If you are using the Command Line Interface (CLI), you can also upgrade the firmware via an SFTP, HTTP, FTP or SCP server for a file transfer.
There are two ways to upgrade firmware:

• One-step firmware upgrade: Use this method when you want the upgrade to take effect immediately.
• Two-step firmware upgrade: Use this method when you to want to download the firmware file now, then activate it on the unit at a later time (such as during an upcoming maintenance window).

Important Consideration when Upgrading Firmware

After upgrading 7.9.2 or later, the SCP is no longer able to send files, reporting the following error: Code = 3: URL using bad/illegal format or missing URL. This is due to a syntax change and customer needs to edit the URL after upgrading to 7.9.2 or 7.9.3.
The URI generic syntax (in RFC 3986) consists of a hierarchical sequence of five components: URI = SCHEME ':' ['//' AUTHORITY] PATH ["?" QUERY] ["#" FRAGMENT]. In this, AUTHORITY = [USER_INFO "@"] HOST [":" PORT]. The AUTHORITY part and the PATH part are isolated by the slash ('/') character if the AUTHORITY exists.
