HPE C7000 Active Standby Onboard Administrator configuration

[RaMa1]

I am working on HP c7000 blade enclosure system. It has dual OAs (OA1 - Active and OA2- Standby) and I have configured both OAs with same subnet IP address.  I have connected both OAs to network switch.  Active OA 1 IP address is pinging and GUI is accessible.  But Standby OA 2 is not pinging and not accessible.  If I connect laptop directly to OA 2 ethernet port, I am able to ping the standby IP address and it is accessible.  I have checked from various aspects but unable to resolve the issue.  Does only Active OA response at a time ? Ideally, both OAs IP should respond over network rite ? Kindly suggest .
