SG300-28 28-Port Gigabit Managed Switch with a SG300-10 10-Port Gigabit Managed Switch Firmware

Hi all 

I bought two SG300-28 28-Port Gigabit Managed Switch, one of the switches came with a SG300-10 10-Port Gigabit Managed Switch Firmware loaded. so i have a 28 port switch telling me that it is a 10 port switch. What can i do to solve this issue ??

I all reddy tried to load the sx300_fw-1476.ros for the 300x-28  i get this error

Go back to the person you bought it from and get it swapped out.

Hi

That is definitely an unusual case, considering that SG300-28 28-Port and SG300-10 10-Port Switches share the same firmware and boot code versions.
I first recommend you to load the latest boot code and firmware version to fix any type of corrupted files in the image.
When you encounter this error
"status: Copy failed , Error Message: Illegal software format "
It is typical because the current boot code and firmware version loaded on the switch are really old and the switch itself won't allow you to jump all the way to the latest one unless you upgrade to a version in between.

If this is the case,  you need to load the latest boot code 1.3.5.06 first using a tftp server such as " tftp 32", and then load a middle firmware version 1.3.7.18.
After this, go ahead and reboot the switch.
After the switch is back on, go ahead and load the firmware 1.4.0.88 following switch reboot.
Then once switch is back on, go ahead and finally load the latest version 1.4.7.06

Latest firmware available is : 1.4.7.06
Latest boot code available is : 1.3.5.06

I hope this information is useful for you.
