# Mainnet

{% hint style="warning" %}
While the Dappnode machines have a large enough SSD to hold both Mainnet and Testnet Ethereum chains, you will have lower performance if you try to run both chains simultaneously.

If you are already running a Testnet chain (e.g., Goerli), it is best to [remove or pause those packages](https://etherfi.gitbook.io/etherfi/~/changes/8Jd9g7SmBTNMrbOKtUZq/operation-solo-staker/additional-configuration#remove-or-pause-packages).
{% endhint %}

Once you have your Dappnode machine set up, the next step is to install the Ethereum staking packages and begin syncing the chain.

The full node can take a few days to sync, so it's good to get that process started as soon as possible.

{% hint style="info" %}
Client diversity is important, so selecting non-majority clients can help to improve the resiliency and health of the network. When selecting which clients to use, take a look at <https://clientdiversity.org> and consider picking clients that are not majority clients.

### Install Ethereum Validator Clients

Navigate to the `Stakers` menu and select the `Ethereum` tab.

Select one Execution Client, one Consensus Client, and optionally MEV Boost.

Apply the changes and the chain will then start syncing.
