### Before You Begin

To start using the EnGenius FitController system, you must prepare the following:

* At least one supported EnGenius Fit-series wireless access point or switch. 
* An existing network connection including DHCP and DNS configuration.

{% hint style="info" %}
**Is Internet connection needed?**

1. FitController is an On-premises solution where permanent internet connection is not necessary.

**Is your Network required with DHCP?**

1. You can either set static IP or DHCP (default setting) on your FitController. 
2. For some circumstances, static IP can be used to ease the debug.

#### Is FitController management within Subnet or Cross Subnet?

1. The discovery of FitController service on the subnet is based on mdns. Therefore, managed device (AP/switch) is basically required to be in the same subnet of FitController. 
2. A newly installed Fit-series device would look for a FitController in the same subnet with mdns and then try to connect with FitController using HTTP/HTTPS protocols. There is a “pairing” procedure in FitController to approve the managed plan on that device. 
3. There are two ways to let FitController service across subnets: 
   * Turn on the mDNS reflector if it is supported in your gateway. In this way, the mDNS message of FitController will be reflected to other subnets. 
   * Utilize DHCP option43 to send FitController service IP to devices.
