# Stopping a router I/O in MediaConnect
<a name="stopping-router-io"></a>

You can stop a router input or output when you need to temporarily pause its operation. When you stop an I/O, it changes to a `Standby` state and stops incurring charges.

Important things to know about stopping I/Os:
+ You can stop and start a router I/O at any time.
+ Stopping a router I/O doesn't affect your other I/Os or their takes.
+ When you stop an I/O, MediaConnect cancels any maintenance restarts that were scheduled when the I/O was started.
+ When you stop an I/O, its routing assignments remain in place. For example:
+ 
  + If you stop an output, it maintains its input assignment and will resume the same connection when restarted.
  + If you stop an input, connected outputs will stop receiving video, but their routing connections and capacity reservations are preserved.

## Prerequisites

Before you start, ensure you have:
+ An active router input or router output
+ No active processes that require the I/O
