# Obtain information
Step 1: Obtain information

Obtain the following information from the operator of the AWS Elemental Link device:
+ The name of the device or devices that will provide your source. For example:

  **hd-re87jr7crey**

  You need two device names for a standard-class input, or one device name for a single-class input. For information about input classes and their uses, see [Choosing the channel class and input class](class-channel-input.md).
+ The Region that the device is configured for, so that you can set MediaLive for that Region. These rules apply:
  + Both devices must be in the same Region.
  + The device, the input for that device, and the channel that uses the input must all be in the same Region.
