MX10004 Management Port LEDs
The two management ports on the RCB of an MX10004 router have LEDs that indicate link status and
link activity. These two ports, located on the RCB panel between the clocking connections and the USB
port, are both labeled MGMT. The left management port (RJ-45) is for 10/100/1000 BASE-T
connections, and the right port (SFP) is for 10/100/1000 BASE-T and small form-factor pluggable (SFP)
1000 BASE-X connections (see
). The copper (RJ-45) port has separate LEDs for
status and activity. The fiber (SFP) port has a combination link and activity LED.
