Initially Configuring the MX480 Router
The MX480 router is shipped with the Junos OS preinstalled and ready to be configured
when the MX480 router is powered on. There are three copies of the software: one on a
CompactFlash card in the Routing Engine, one on a rotating hard disk in the Routing
Engine, and one on a USB flash drive that can be inserted into the slot in the Routing
Engine faceplate.
When the router boots, it first attempts to start the image on the USB flash drive. If a
USB flash drive is not inserted into the Routing Engine or the attempt otherwise fails, the
router next tries the CompactFlash card (if installed), and finally the hard disk.
You configure the router by issuing Junos OS command-line interface (CLI) commands,
either on a console device attached to the
CONSOLE port on the Routing Engine, or over
a telnet connection to a network connected to the ETHERNET port on the Routing Engine.
Gather the following information before configuring the router:
• Name the router will use on the network
• Domain name the router will use
• IP address and prefix length information for the Ethernet interface
• IP address of a default router
• IP address of a DNS server
• Password for the root user
This procedure connects the router to the network but does not enable it to forward
traffic. For complete information about enabling the router to forward traffic, including
examples, see the Junos OS configuration guides.
To configure the software:
1. Verify that the router is powered on.
2. Log in as the “root” user. There is no password.
