AP8886 : retrieve snmp metrics

[ano9]

I just buy ap8886. I need to store and graph consumption metrics, output phases and other stuff queried on Pdu ap8886. i run snmpwalk without finding value i looked for.

It's like oid requested are not present/avalaible for this model. For example this oid doesn't return any value : 

1.3.6.1.4.1.318.1.1.26.4.3.1.5

correponds to power consumption rack.

I try upgrading firmware but i fall into this issue : 

target distribution does not match target device platform;this could be due to a corrupt distribution

Thank you for your help.

Best regards.
