Hello Muhammed,
"" PXE-E61: Media test failure, check cable "'
Above message says you have enabled LAN / PXE boot in boot order but have not connected physical cable to LOM NIC ports.
To achieve your goal of deploying vWLC and Prime VMs, you first need to start with configuring CIMC.
Once you can reach CIMC over the network, you can use KVM and install the ESXi.
After installing ESxi, you need to follow the installation docs of vWLC and Prime.
