Unable to Upgrade / Downgrade new 7150-48ZP model switches in firmware version 8095k.

Chandini — Thu, 31 Aug 2023 16:54:12 GMT

Error encountered below:

Reason for getting the above error:

The TI PoE chipset is different for the newly released/manufactured switches with 7150-48ZP Model.
These PoE chipset work from version 8095k and above in 8095 major release and 9010h and above in 9010 major releases

Hence if you need the switches to operate with PoE then you will need to retain 8095k. If you want to add these switches to the cloud, you need to wait for 9010h release for TI PoE chipset to work.

If you try adding switches with TI PoE issue to cloud, you will encounter below error messages.

How to identify the 7150-48ZP switches have new PoE chipset:

Check the MCU details of the switch using “dm hwinfo” command. These are mostly 2023 batches of switches which have new TI PoE chipset.

ICX7150-48ZP Switch#dm hwinfo

HW Ver: 3.1 [Production-2], Main board CPLD Rev: 0.4.a

NAND Type: Micron NAND 2GiB (x 1)

After Rebooting the switch on 9010 version:

You will see above outputs for PoE on 9010f version.

Workaround:

If you want to use switch model 7150-48ZP switch model with TI PoE chipset in cloud, then wait for 9010h version to have PoE feature and bring these switches up in cloud.
If you don’t need the switch to be part of cloud and need PoE feature, then retain the switch in 8095k version.
