MX2008 Management and Console Port Specifications and Pinouts
RJ-45 Connector Pinouts for MX Series CB-RE or RCB Auxillary and Console Ports
The ports–labeled—AUX and CONSOLE—on the Control Board and Routing Engine (CB-RE) or the Routing and Control Board (RCB) are asynchronous serial interfaces that accept an RJ-45 connector. The ports connect the Routing Engine to an auxiliary or console management device. Table 1 describes the RJ-45 connector pinout.
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.

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).
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 2 describes the RJ-45 connector pinout.
