When the switch boots, it first attempts to start the image on the USB flash drive. If there is no USB
flash drive inserted into the RE module or if the attempt otherwise fails, the switch next attempts to
start the software from the CompactFlash card (if installed), and finally from the hard disk.
You configure the switch by issuing Junos OS command-line interface (CLI) commands, either on a
console device attached to the console (CONSOLE) port on the primary RE module, or over a telnet
connection to a network connected to the Ethernet management (<...>) port on the primary RE module.
Gather the following information before configuring the switch:
• Name the switch will use on the network
• Domain name the switch will use
• IP address and prefix length information for the Ethernet interface
• IP address of a default switch
• IP address of a DNS server
• Password for the root user

complete information about enabling the switch to forward traffic, including examples, see the Junos OS
configuration guides.
