Updating the firmware

The Cisco Nexus 3550-F (formerly ExaLINK Fusion) can be updated by one of following methods:

  • SFTP
  • USB
  • TFTP
  • HTTP

The updated firmware is made available in a tar archive. There are various ways to get the tar file onto the Nexus 3550-F. The update process will verify the integrity of the contents of the tar file before applying the update and rebooting the Nexus 3550-F. The update process takes a few minutes.

Please refer to the firmware downloads page for the firmware files and release notes.

Note

To install firmware releases from 1.14.0 onwards, the device must be running 1.13.0 or later. For devices running earlier releases, please install 1.13.0 before updating to later releases.

Nexus 3550-Fs with serial numbers EXAFSN-C-xxxxx require 1.14.0 or later. It is not possible to install earlier releases on these devices.

Updating with SFTP

From Windows, a graphical tool like winscp can be used to transfer the release tar to the Nexus 3550-F. SFTP is available as a command line tool as well.

$ sftp admin@192.168.220.10
admin@192.168.220.10's password:
sftp> put fusion_update.tar update/release.tar

Once the release is available on the Nexus 3550-F, the firmware is updated using the command line interface.

admin@N3550-F> configure update file release.tar
Starting update process...

Updating with a USB drive

The release tar can also be installed from a USB drive. The drive should be formatted with vfat, and the tar file should be copied onto the first partition. Plug the USB drive into the Nexus 3550-F, and then use the command line interface.

admin@N3550-F> configure update usb release.tar
Starting update process...

Updating with TFTP

If the release tar is made available though a TFTP server, then it can be copied and installed through the command line interface.

admin@N3550-F> configure update tftp 192.168.220.160 /path/to/update_fusion.tar
Starting fetch and update process...

Updating with HTTP

The Nexus 3550-F can download updates from a HTTP or HTTPS server:

admin@N3550-F> configure update http https://example.com/exalink_fusion_1.6.0.tar
Starting fetch and update process...
