How to upgrade firmware and boot image on cisco SG300 switch
Having bought a cisco SG300-10 switch the issue of upgrading the firmware image and the boot image soon arises.
The process is done via CLI and uses a TFTP server, because uploading the boot image is not possible via HTTP. A tutorial to set up a TFTP server on Linux is described here.
The update to the current available version (Release 1.3.5.58) is not quite intuitive as is coming as a zip archive with two files:
The update to the current available version (Release 1.3.5.58) is not quite intuitive as is coming as a zip archive with two files:
- sx300_boot-13506.rfb --> this is the boot image
- sx300_fw-13558.ros --> this is the firmware image
The initial state of the switch is:
SW2-GS300#sh ver SW version 1.3.0.62 ( date 02-May-2013 time 14:55:01 ) Boot version 1.1.0.6 ( date 11-May-2011 time 18:31:00 ) HW version V02
Before upgrading the boot image it is a good idea to back-up the current one (via TFTP).
The upgrade is straight forward as:
- For uploading the firmware image:
- For uploading the firmware image:
SW2-GS300#copy tftp://tftp_IP_address/path_to_the_file/sx300_fw-13558.ros image 09-Jan-2014 20:16:21 %COPY-I-FILECPY: Files Copy - source URL tftp://tftp_IP_address/sx300_fw-13558.ros destination URL flash://image !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Copy: 6976867 bytes copied in 00:02:19 [hh:mm:ss]
- For uploading the boot image:
SW2-GS300#copy tftp://tftp_IP_address/path_to_file/sx300_boot-13506.rfb boot 09-Jan-2014 20:30:21 %COPY-I-FILECPY: Files Copy - source URL tftp://tftp_IP_address/sx300_boot-13506.rfb !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Copy: 393232 bytes copied in 00:00:08 [hh:mm:ss]
Then is needed to change the active boot image and reboot the switch:
SW2-GS300#sh bootv Image Filename Version Date Status ----- --------- --------- --------------------- ----------- 1 image-1 1.3.0.62 02-May-2013 14:55:01 Active* 2 image-2 1.3.5.58 10-Oct-2013 17:15:41 Not active SW2-GS300#boot system image-2 SW2-GS300#reload
