Mx Routing Engine Leds - Juniper MX960 Hardware Manual

ETHERNET or MGMT—Connects the Routing Engine through an Ethernet connection to a management
LAN (or any other device that plugs into an Ethernet connection) for out-of-band management. The port
uses an autosensing RJ-45 connector to support 10-Mbps or 100-Mbps connections. Two small LEDs
on the right of the port indicate the connection in use: the LED flashes yellow or green for a 10-Mbps
or 100-Mbps connection, and the LED is light green when traffic is passing through the port.
