Initially Configuring the ACX2000 or ACX2100 Router

The ACX2000 and ACX2100 routers ship with Junos OS preinstalled and ready to be configured when
the router is powered on. One 4-GB internal NAND Flash memory device is divided into two partitions
(da0s1 and da0s2). One partition is marked as the active partition, and the other partition functions as an
alternate partition. The NAND Flash device acts as the hard drive. Two USB ports on the front panel accept
USB storage devices (usb0 and usb1) that can also function as alternate boot devices.
When the router boots, it first attempts to start the image on the USB Flash memory device. If a USB Flash
memory device is not inserted into the router or the attempt otherwise fails, the router next tries the
active partition on the NAND Flash device, and then tries the alternate partition on the NAND Flash device.
You configure the router by issuing Junos OS command-line interface (CLI) commands, either on a console
device attached to the CONSOLE/AUX port on the front panel, or over a telnet connection to a network
connected to the Routing Engine MGMT port on the front panel.
Gather the following information before configuring the router:
Name that the router will use on the network
Domain name that 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
