Upgrading SF200-24P firmware questions

[JOHN THIEN]

I have an SF200-24P running FW 1.2.7.76 and boot 1.1.0.6. I wanted to update the firmware in hopes it would help with a weird problem I'm having with a UC320 phone system so I downloaded from Cisco Sx200_FW_Boot_1.4.0.88.zip. The instructions say if I'm upgrading from something earlier than 1.3.5, I first need to upgrade the device image to "to image 1.3.5 or 1.3.7 and the latest boot file (1.4.0.x)." In the ZIP file I downloaded from Cisco are two files: sx200_boot-13506.rfb sx200_fw-14088.ros Are they just saying I first need to load the sx200_boot-13506.rfb, then load the sx200_fw-14088.ros file? Or do I need to download a previous copy of the firmware? If that is the case, do I just download 1.3.5.58 and install the .ros file in that archive, wait for the switch to become ready, and load the .ros file from the 1.4.0.88 archive? I'm unclear on the process of getting my switch with old firmware updated to the newest firmware. So any tips would be appreciated.

Okay that is helpful but I'm still not clear on whether I need to download and install the two files in 1.3.5.58 first, and then the sx200_fw-14088.ros from the 1.4.0.88

Or, can I simply use the sx200_boot-13506.rfb along with the sx200_fw-14088.ros and skip the 1.3.5.58 firmware?  Any tips there?

Hi,

First upgrade to version sx200_fw_1.3.7.18.ros and Boot code sx200_boot-13506.rfb.After that upgrade to  latest firmware sx200_fw-14088.ros .Not required to upgrade the boot code .since boot code is same for both version firmware.
