Mx10003 Rcb Leds - Juniper MX10003 Hardware Manual

CON—Connects the RCB to a system console through a serial cable with an RJ-45 connector.
MGMT—Connects the RCB 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, 100-Mbps, or 1000-Mbps connections. Two small LEDs on the
port indicate the connection in use: the LED flashes yellow or green for a 10-Mbps, 100-Mbps, or
1000-Mbps connection, and the LED is lit green when traffic is passing through the port.
BITS—Building-integrated timing supply (BITS) external clocking interface for connection to external
clocking devices.
ToD—Time-of-day (TOD) port on the front panel of the router allows you to connect external timing
signal sources.
NOTE: This port is reserved for future use.
10MHZ (one input and one output)—The 10-MHz timing connectors on the front panel of the router
connect to external clock signal sources. The clocking ports provide the synchronized output clocks from
any one of the reference clock inputs based on the clock's priority.
PPS (one input and one output)—1-pulse-per-second (PPS) connectors on the front panel of the router
connect to external clock signal sources. The clocking ports provide the synchronized output clocks from
any one of the reference clock inputs based on the clock's priority.
USB—Provides a removable media interface through which you can install Junos OS manually. Junos
OS supports USB version 1.0 and later.

MX10003 RCB LEDs

The Routing and Control Board (RCB) is an integrated board and a single FRU that provides Routing Engine
and Control Board functionality.
The LEDs—labeled ONLINE, MST, OK/FAIL, LINK, GPS, BITS—are located directly on the faceplate of the
RCB. Table 17 on page 52 describes the functions of the Routing Engine interface of the RCB.
