2. Connect the console port on the rear panel of the switch to a laptop or PC by using the RJ-45 to DB-9 serial port adapter.
NOTE: You can also use the mini-USB port on the front panel to connect the switch to a laptop or PC (see the
documentation at https://www.juniper.net/documentation/en_US/release-independent/junos/topics/task/installation/
port-ex-series-mini-usb-management-console-connecting.html).

6. When prompted, reenter the password.

NOTE: You will not be able to log in to the switch as the root user through Telnet. Root login is allowed only through
SSH.
•
The default option for SSH is yes. Press Enter to accept the default option and enable SSH.
•
The default option for Telnet is no. At the prompt, enter yes and press Enter to enable Telnet.
8. Configure in-band management or out-of-band management:
•
In in-band management, you configure a network interface or an uplink module (expansion module) interface as the
management interface and connect it to the management device.
In this scenario, can do either of the following:
•
Use the automatically created VLAN named default for management of all data interfaces as members of the default
VLAN. Specify the management IP address and the default gateway.
•
Create a new management VLAN. Specify the VLAN name, VLAN ID, management IP address, and default gateway. Select
the ports that must be part of this VLAN.
•
In out-of-band management, you use a dedicated management channel (MGMT port) to connect to the management
device. Specify the IP address and gateway of the management interface. Use this IP address to connect to the switch.
9. (Optional) Specify the SNMP read community, location, and contact to configure SNMP parameters.
10. (Optional) Specify the system date and time. Select the time zone from the list.
