When you visit the server settings page, a check will automatically be made to see if there is an updated version of Plex Media Server available. Information about the update status is displayed here, including the ability to download or install an update if one is available.
The friendly name is used to identify your Plex Media Server. This will show up for you when selecting your Server in a Plex App as well as if you share Libraries with others, for instance. You might choose a name such as "Office Library" or "Kim's Server". If you don't set a friendly name yourself, the computer's name will be used by default.
Send anonymous usage data to Plex
Plex uses information about media matching and other basic usage to help improve your experience using Plex. You can choose to help this by allowing the Plex Media Server to send anonymous data back to Plex.
Automatically check for updates
Choose whether or not your Plex Media Server will download (but not install) an update when one is available for it.
Note: If an update is available, Windows and OS X systems will be able to launch the installation from Plex Web App. For Linux and NAS users, it will provide a link to allow you to download the update for now.
Click on the Show Advanced button at the top right of the settings area to toggle display of advanced settings. Be careful when adjusting or using advanced settings.
Plex Media Server debug logging
Enable this to include debug information in the various Plex Media Server logs. This should be enabled if investigating an issue or seeking assistance by posting in the Plex support forums.
Plex Media Server verbose logging
When enabled, Verbose-level information will be included in the various Plex Media Server logs.
Warning!: This should not typically be enabled, even when investigating most issues. Only enable this if specifically instructed to do so as it can very quickly fill log files and the information is not typically useful for most troubleshooting.
Allow Plex Media Server tokens in logs
By default, your Plex tokens are not displayed in your log files. Tokens should be treated as secure information and you should generally refrain from sharing information that includes your token. Only enable this option if specifically instructed to do so during an investigation.
For users with a Plex Pass subscription, you can choose whether or not you look for "Stable" or "Plex Pass" updates whenever the server does a check.
Tip!: The Plex Pass channel may have preview releases available. These can have new functionality or fixes and be available early, but are also more prone to have unanticipated issues.

OS X Specific Settings
Show a dock icon
By default the Plex Media Server does not appear as an item in your Dock on OS X. (It will always appear in the top menubar.) You can enable this option to have the Server appear as a standard Dock icon.

Ask to add a login item for externally mounted drives
When adding a source from an external or network mounted drive to a Library, you can be asked whether you wish to have that drive added to your Login Items in OS X.

Windows Specific Settings
The path where local application data is stored
You can set the location where your Plex Media Server data directory is located. This is the path to the directory containing the
Plex Media Server folder.
Note: Altering this setting will not move the data for you. You will need to ensure the data is in the desired location yourself.

Size of IPC buffer (in bytes) when streaming transcodes
You can adjust the size of the IPC (inter-process communication) buffer.
Warning!: DO NOT adjust this if you don't know exactly what it does. This is not a setting a user should normally be changing.
Support Away Mode when preventing system sleep (Vista and above)
The "Away Mode" in Windows Vista and newer is intended "to provide a 'user not present' state to the machine so you can walk away, know that your recording is going to happen (or not be interrupted) while not badgering the user with a screen, audio, etc.".
In the context of Plex, it allows the Plex Media Server to continue functioning and streaming.
