Cisco SG300-28P Firmware Upgrade Failure Loop

[vasilioshapsis]

Greetings,

We currently manage a network of approximately 10 switches all of which are Cisco SG300-28P. The firmware version on these switches is set to version 1.2.7.76 of which we require to upgrade to the latest version which is 1.3.5.58 as supplied by Cisco. Upon uploading, upgrading and rebooting the switch, the following error displays in a continuous loop:

I have tried resetting the switch by holding down the reset button, as well as powering off the switch and powering it back up with the reset button pressed. Is there no way of resolving this issue and reverting back to the previous firmware that originally worked?

Many thanks for any assistance.

Hi Vasilios,

Unfortunately there is no correlation to specific firmware but rather to the actual upgrade process.

we are still working on root cause and currently the only solution is to contact Small Business Support team as they have information regarding the latest process for such an error.

Hi Aleksandra,

We reverted the switch back to a working configuration and left the firmware update, so long as the network is functional i dont see why i should worry upgrading the firmware. I thank you for your assistance though.

I have similar issue, with a SG 500-28P

In console show:

i2c_status fail : 1
i2c_status fail : 1
i2c_status fail : 1
...

In the log, from the Web Intreface says:

%HAL_config_poe-A-POEFailDetected: POE ERROR (i2c_read_mem failed addr ....) was detected: POE is Disabled untill Reset.
%HAL_config_poe-A-POEFailDetected: POE ERROR (i2c_read_mem failed addr ....) was detected: POE is Disabled untill Reset.
%HAL_config_poe-A-POEFailDetected: POE ERROR (i2c_read_mem failed addr ....) was detected: POE is Disabled untill Reset.
...
 

I was do, the Factory Reset, upgrade at next firmware, cold start, and the error still continuous.
Any ideas?

Everything that i did, didn't work. Update the boot code and firmware code to the last version; don't solve the issue.

I contacted the Cisco SMB Support and they give me an RMA for my switch.
Easy: The replacement it's the solution.
