Could an Onboard Administrator Update Generate a Losing Connection with Pass-Thru Modules?

Howdy!

Gianluca had a great question about OA updates and losing connectivity:  

***************************

Hello Guys,

I need your feedback about an OA Firmware update.

My customer has installed OA Firmware 3.60 and I need to update it to version 4.40.

First question:

Do you know why version 4.40 is not available on HP.com at the moment?

There are 4 Ethernet Pass-Thru Modules in this enclosure (Firmware version 3.0.3 as reported in "update show").

Device  Name                                                                           Location Version    New Version

-----------------------------------------------------------------------------------

TRAY  | BladeSystem c7000 Onboard Administrator Tray|        | 1.7        | 1.7 

LCD     | BladeSystem c7000 Insight Display                                     | 2.2.2    | 2.2.2

ICBAY | HP 1Gb Ethernet Pass-Thru Module for c-Class  | 1A    | 3.0.3    | 3.0.3

ICBAY | HP 1Gb Ethernet Pass-Thru Module for c-Class  | 2A    | 3.0.3    | 3.0.3

ICBAY | HP 1Gb Ethernet Pass-Thru Module for c-Class  | 5A    | 3.0.3    | 3.0.3

ICBAY | HP 1Gb Ethernet Pass-Thru Module for c-Class  | 6A    | 3.0.3    | 3.0.3

Second question:

When I upgrade OA firmware from 3.60 to 4.40, will the pass-thru Firmware be updated too? 

Could this update generate a restart of these Pass-Thru Modules (losing connection on mezzanine card as a consequence)?

Thanks in advance

Radi was kind enough to provide the link to exactly what Gianluca needed:

Pass-Thru modules are updated by updating OA Firmware.

Cheers,
