The AT-MCR1 is a single slot, rack-mountable chassis, capable of housing any of the range of Fast Ethernet and Gigabit Media Converters and Bridging Media Converters. The chassis features an internal power supply, which negates the need to use the external power adapter shipped with the media converter. A front panel LED power indicator shows the user when power is applied to the chassis. All the standalone Media Converters and Bridging Media Converters can be hot inserted and removed from the chassis, thus removing the need to power down the chassis for maintenance and upgrades.
