can't update firmware of ESXi with OME

HI,

i want to use OME for firmware updates of ESXi's

Here's my conf :

OME : 1.2.0.3441

ESXi 5.1 build 1483097

Package OpenManage 7.3.0.2 for ESXi510 installed via UpdateManager

I've set a discover and inventory range for ESXi using WS-man only, set time-out at 200 seconds, 10 retries, secure mode, with no domain verification and secured site

My servers are R/M610 and 620 and PE2950

I can't find them in compliant or non-compliant system, or non-inventoried systems, why?
