RJ-45 Connector Pinouts for an MX Series CB-RE or RCB Management
Port
The port on the Control Board and Routing Engine (CB-RE; Routing and Control Board (RCB)) labeled
MGMT is an autosensing 10/100/1000-Mbps Ethernet RJ-45 receptacle that accepts an Ethernet cable
for connecting the Routing Engine to a management LAN (or other device that supports out-of-band
management).
NOTE: In routers where the Routing Engine and Control Board (CB) are integrated into a single
board, a CB-RE is known as Routing and Control Board (RCB). The RCB is a single FRU that
provides Routing Engine and CB functionality.
Table 44 on page 156 describes the RJ-45 connector pinout.
