assign an IP address to the switch
Configure a DHCP server on your network to meet your network requirements. You can
configure an EX Series switch to operate as a DHCP server. For more information, see
"Configuring DHCP Services (J-Web Procedure)" on page 541.
Create one of the following configuration files, and store it on a TFTP server (or HTTP
server or FTP server) in the network:

Physically attach the switch to the network using a Gigabit Ethernet port.
If you configure the DHCP server to provide only the TFTP server hostname, add an IP
address-to-hostname mapping entry for the TFTP server to the DNS database file on
the Domain Name System (DNS) server in the network.
If the new switch is not on the same network segment as the DHCP server (or other
device providing IP address resolution), configure an existing device as an intermediate
device to receive TFTP and DNS requests and forward them to the TFTP server and
the DNS server. You must configure the LAN or serial interface on the intermediate
device with the IP addresses of the hosts providing TFTP and DNS services. Connect
this interface to the new switch.
