I already wrote a blog post how you can enable SSH on VMware ESXi 5.0 and VMware ESXi 4.1. As before enabling SSH on VMware ESXi 5.1 or VMware vSphere Hypervisor 5.1 is pretty easy.
- On the start screen press F2 for “Customize System”

- Login with the local password, and on the settings page select and enter Troubleshooting Options

- Click on Enable SSH to activate SSH on your VMware ESXi 5.1 host


Thanks Tomas.
In my case, I needed to configure firewall additionally.
