support Spanning Tree or Fast Spanning Tree protocols. By default,
transmission of data will travel via the primary path. If a link failure is
detected, transmission will automatically be switched to the secondary
path by Spanning Tree Protocol, delivering non-stop network connectivity.
LEDs
Front panel LEDs provide at-a-glance network status and real-time
connectivity information.
NOTE:
The PWR (power) LED is located on
the rear panel on some models.
