Connecting the NFX150 to the Network
Connecting an NFX150 Device to a Network for Out-of-Band Management
You can monitor and manage the NFX150 device using a dedicated management channel. NFX150 devices have one management port, eight 1-Gigabit Ethernet RJ-45 ports, two 1-Gigabit Ethernet RJ-45 network/uplink ports, two 1-Gigabit Ethernet small form-factor pluggable (SFP) ports, and two 1/10-Gigabit Ethernet SFP+ ports. Use the management port to connect the NFX150 device to a network for out-of-band management.
Ensure that you have an appropriate cable available.
To connect an NFX150 device to a network for out-of-band management (see Figure 1):
- Connect one end of the cable to the management port (labeled
MGMT
) on the NFX150 device. - Connect the other end of the cable to the management switch (see Figure 1).

Connecting an NFX150 Device to a Management Console
NFX150 device has a console port with an RJ-45 connector. Use the console port to connect the device to a management console or to a console server.
Ensure that you have an RJ-45 to DB-9 rollover cable available. An RJ-45 cable with an RJ-45 to DB-9 adapter is provided with the device.
If your laptop or PC does not have a DB-9 male connector pin and you want to connect your laptop or PC directly to the NFX150 device, use a combination of the RJ-45 cable and RJ-45 to DB-9 adapter supplied with the device and a USB to DB-9 male adapter. You must provide the USB to DB-9 male adapter.
To connect the NFX150 device to a management console (see Figure 2 and Figure 3):
- Connect one end of the Ethernet cable to the console port
(labeled
CON
). - Connect the other end of the Ethernet cable into the console server (see Figure 2) or management console (see Figure 3).


Connecting an NFX150 Device to a Management Console Using Mini-USB Type-B Console Port
You can configure and manage NFX150 devices by using the RJ-45 console port or the Mini-USB Type-B console port. However, the console input will be active only on one port at a time—only one port will be set active at a time.
By default, the RJ-45 port is set as an active console port and the Mini-USB Type-B port is the passive console port.
If your laptop or PC does not have a DB-9 male connector pin or RJ-45 connector pin, you can connect your laptop or PC directly to an NFX150 device by using a mini-USB cable that has a Standard-A USB connector on one end and a Mini-USB Type-B (5 pin) connector on the other end.
This section describes the process of connecting an NFX150 device to the management console by using the Mini-USB Type-B console port.
For information about configuring and managing an NFX150 device by using the RJ-45 console port, see Connecting an NFX150 Device to a Management Console.
Before you begin connecting an NFX150 device by using the Mini-USB Type-B console port:
Ensure that the USB to Serial driver is installed on the host machine. You can download the driver from https://webdownload.juniper.net/swdl/dl/secure/site/1/record/5029.html
Ensure that the hyper terminal properties of the console server or laptop are set as follows:
Baud rate—9600
Flow control—None
Data—8
Parity—None
Stop bits—1
DCD state—Disregard
Ensure that you have the following parts and tools available:
1 mini-USB cable with Standard-A and Mini-USB Type- B (5-pin) connectors (not provided).
To connect the NFX150 device to the console using Mini-USB Type-B console port:
- Connect the Standard-A connector of the mini-USB cable to the host machine (PC or Laptop).
- Connect the Mini-USB Type-B (5-pin) connector of the mini-USB
cable to the Mini-USB Type-B console port (labeled
CON
) on the NFX150 device. - Set the Mini-USB Type-B console port as the active console
port by using the command port-type.
- Reboot the NFX150 device.
After the connection is established, the Mini-USB Type-B becomes the active console port. The host machine connected to the Mini-USB Type-B console port displays log messages and lets you control NFX150 device functionality through it.
Installing a Transceiver in an NFX150 Device
The transceivers for the NFX150 devices are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace them without powering off the device or disrupting device functions.
Before you begin installing a transceiver in an NFX150 device, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings for the NFX150 Devices).
Ensure that you have a rubber safety cap available to cover the transceiver.
To install a transceiver in a NFX150 device:
To avoid electrostatic discharge (ESD) damage to the transceiver, do not touch the connector pins at the end of the transceiver.
- Remove the transceiver from its bag.
- Check to see whether the transceiver is covered by a rubber
safety cap. If it is not, cover the transceiver with a rubber safety
cap.
Warning Do not leave a fiber-optic transceiver uncovered except when inserting or removing a cable. The rubber safety cap keeps the port clean and prevents accidental exposure to laser light.
- If the port in which you want to install the transceiver is covered with a dust cover, remove the dust cover and save it in case you need to cover the port later.
- Using both hands, carefully place the transceiver in the
empty port. The connectors must face the device chassis.
Caution Before you slide the transceiver into the port, ensure that the transceiver is aligned correctly. Misalignment might cause the pins to bend, making the transceiver unusable. See Figure 5 for the correct orientation for your device.
- Slide the transceiver in gently until it is fully seated. See Figure 5 for an example of inserting an SFP or SFP+ transceiver.
- Remove the rubber safety cap when you are ready to connect
the cable to the transceiver.
Warning Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.


Connecting a Fiber-Optic Cable to an NFX150 Device
You can connect fiber-optic cables to the field-replaceable unit (FRU) optical transceivers installed in NFX150 devices.
Before you connect a fiber-optic cable to an optical transceiver installed in an NFX150 device, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings for the NFX150 Devices).
To connect a fiber-optic cable to an optical transceiver installed in an NFX150 device:
Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.
Do not stare into the laser beam or view it directly with optical instruments even if the interface has been disabled.
- If the fiber-optic cable connector is covered by a rubber safety cap, remove the cap. Save the cap.
- If the optical transceiver is covered by a rubber safety cap, remove the cap. Save the cap.
- Insert the cable connector into the optical transceiver (see Figure 6).
- Secure the cables so that they are not supporting their
own weight. Place excess cable out of the way in a neatly coiled loop.
Placing fasteners on a loop helps cables maintain their shape.
Caution Do not bend fiber-optic cables beyond their minimum bend radius. Bending the cables beyond their minimum bend radius can damage the cables and cause problems that are difficult to diagnose.
Caution Do not let fiber-optic cables hang free from the connector. Do not allow fastened loops of cables to dangle, which stresses the cables at the fastening point.
