Mount the NFX250 | 2
Connect Power to the NFX250 | 3
To mount and connect power to the Juniper Networks®NFX250 Network Services Platform, and perform initial
configuration, you need:
•Electrostatic discharge (ESD) grounding strap (not provided)
•One pair of front-mounting rails (provided)
•Twelve screws to secure the mounting rails and mounting blades to the chassis (provided)
•Eight screws to secure the chassis and mounting-blades to the rack (not provided)
•Screwdriver appropriate for your rack mounting screws (not provided)
•An AC power cord with plugs appropriate for your geographical location (not provided)
•RJ-45 cable and RJ-45 to DB-9 serial port adapter (provided)
•Management host, such as a PC or laptop, with a serial port (not provided)
•(Optional) A grounding cable (minimum 14 AWG (2 mm²), minimum 90°C wire), a grounding lug (Panduit LCC10-14BWL
or equivalent), a pair of 10-32x.25-in. screws, and a pair of flat washers (not provided). For information about installing
the grounding cable, see the NFX250 documentation at https://www.juniper.net/documentation/product/en_US/nfx250.
Mount the NFX250
You can mount an NFX250 device on two posts of a 19-in. rack by using the mounting brackets provided with the device.
The device weighs approximately 9.4 lb (4.3 kg). Two persons are required for mounting the device.
1. Attach the ESD grounding strap to your bare wrist and to a site ESD point.
NOTE: If you are mounting multiple units in the rack, mount the heaviest unit at the bottom and mount the
others from bottom to top in order of decreasing weight.
2. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and secure it to the
building structure.
3. Align the mounting brackets along the front or rear of the side panels of the chassis— depending on whether you will
front-mount or rear-mount the device—and attach the mounting brackets to the chassis by using the mounting screws.
Tighten the screws.
4. Have one person grasp both sides of the device, lift the device, and position it in the rack, aligning the mounting bracket
holes with the threaded holes in the rack rail. Align the bottom hole in each mounting bracket with a hole in each rack
rail, making sure that the chassis is level.
5. Have the second person use the mounting screws (and cage nuts and washers if your rack requires them) to screw the
mounting bracket to the rack.

Connect Power to the NFX250
1. Attach a grounding cable to earth ground and then attach it to the chassis grounding points.
NOTE: We recommend grounding for AC-powered systems. An AC-powered device gets additional grounding
when you connect the power supply in the device to a grounded AC power outlet by using the power cord.
The NFX250 device uses a fixed, internal AC power supply.
2. Set the power switch to the OFF (O) position.
3. Insert the power cord plug into the power source outlet.
4. Insert the power cord coupler firmly into the inlet.
5. Set the power switch to the ON (|) position.
6. Verify that the power LED is lit green and on steadily.
Step 2: Up and Running

Set Parameter Values | 4
Perform the Initial Configuration | 4
3
You must perform the initial configuration of the device through the console port. Before you begin, set the following
parameter values in the console server or the management host:
Set Parameter Values
•Baud rate—9600
•Flow control—None
•Data—8
•Parity—None
•Stop bits—1
•DCD state—Disregard
Perform the Initial Configuration
To configure the device from the console:
1. Connect the console port to a laptop or PC using the provided RJ-45 cable and RJ-45 to DB-9 serial port adapter. The
console (CON) port is located on the management panel of the device. The Juniper Device Manager (JDM) CLI prompt
appears.
NOTE: If the boot process is completed before you connected to the console port, you might need to press
the Enter key for the prompt to appear. For more information on JDM, see the JDM documentation at
https://www.juniper.net/documentation/en_US/junos/topics/topic-map/jdm_cli_overview.html.
2. Log in as the root user. There is no password.
login: root
3. Enter configuration mode:
root@jdm% cli
4. Enter configuration mode:
root@jdm> configure
4
5. Specify a password for the root administration user account:
[edit]
root@jdm% set system root-authentication plain-text-password
New password: password
Retype new password: password
6. (Optional) Configure the name of the device. If the name includes spaces, enclose the name in quotation marks (“ ”):
[edit]
root@jdm# set system host-name host-name
7. Configure the default gateway:
[edit]
root@jdm# set route destination next-hop address
8. Configure the IP address and prefix length for the device management interface:
[edit]
root@jdm# set interfaces eth0 unit 0 family inet address address/prefix-length
NOTE: The management port, eth0, is located on the front panel of the NFX250 device.
9. Enable Telnet service. By default, Telnet is not enabled and SSH is enabled:
[edit]
root@jdm# set system services telnet
10. Commit the configuration to activate it on the device:
[edit]
root@jdm# commit

Safety Warnings Summary
This is a summary of safety warnings. For a complete list of warnings, including translations, see the NFX250 documentation
at https://www.juniper.net/documentation/product/en_US/nfx250.
WARNING: Failure to observe these safety warnings can result in personal injury or death.
•Permit only trained and qualified personnel to install or replace switch components.
•Perform only the procedures described in this quick start and the NFX250 documentation. Other services must be
performed only by authorized service personnel.
•Before installing the device, read the planning instructions in the NFX250 documentation to make sure that the site
meets power, environmental, and clearance requirements for the device.
•Before connecting the device to a power source, read the installation instructions in the NFX250 documentation.
•The NFX250 device weighs approximately 9.4 lb (4.3 kg). Manually installing the device in a rack at a height above 60
in. (152.4 cm) requires two persons; one to lift the device and the second to install the mounting screws. To prevent
injury while lifting, keep your back straight and lift with your legs, not your back.
•If the rack has stabilizing devices, install them in the rack before mounting or servicing the device in the rack.
•Before installing or after removing an electrical component, always place it component-side up on an antistatic mat
placed on a flat, stable surface or in an antistatic bag.
•Do not work on the device or connect or disconnect cables during electrical storms.
•Before working on equipment that is connected to power lines, remove jewelry, including rings, necklaces, and watches.
Metal objects heat up when connected to power and ground and can cause serious burns or become welded to the
terminals.
