MX104 Routing Engine Components
Five ports, located on the right side of the Routing Engine, connect the Routing Engine
to one or more external devices on which system administrators can issue Junos OS
command-line interface (CLI) commands to manage the router.
The Routing Engine consists of the following components:
•
1.8-GHz CPU—Runs Junos OS to maintain the router's routing tables and routing
protocols.
•
4-GB DDR3 RAM (mini DIMM)—Provides storage for the routing and forwarding tables
and for other Routing Engine processes.
•
8-GB on-board NAND Flash—Provides primary storage for software images,
configuration files, and microcode. The NAND flash is fixed and is inaccessible from
outside the router.
•
Interface ports—Provides access to management devices.
•
AUX—Not supported.
•
CONSOLE—Connects the Routing Engine to a system console through a serial cable
with an RJ-45 connector.
•
ETHERNET—Connects the Routing Engine through an Ethernet connection to a
management LAN (or any other device that plugs into an Ethernet connection). The
port uses an autosensing RJ-45 connector to support 10-Mbps, 100-Mbps, or
1000-Mbps connections. Two small LEDs on the right of the port indicate the
connection in use: see “MX104 Routing Engine LEDs” on page 23.
•
Two USB ports—Provide a removable media interface through which you can install
the Junos OS manually. Junos OS supports USB version 1.0.
•
Online/Offline button—Takes the Routing Engine online or offline when pressed (see
“MX104 Routing Engine Buttons” on page 22).
•
Reset button—Reboots the Routing Engine when pressed (see “MX104 Routing Engine
Buttons” on page 22).
•
LEDs—Indicates the status of the Routing Engine and its ports (see “MX104 Routing
Engine LEDs” on page 23)
