Connecting the MX480 to the Network

Tools and Parts Required for MX480 Router Connections

To connect the router to management devices and line cards, you need the following tools and parts:

  • Phillips (+) screwdrivers, numbers 1 and 2

  • 2.5-mm flat-blade (–) screwdriver

  • 2.5-mm Phillips (+) screwdriver

  • Wire cutters

  • Electrostatic discharge (ESD) grounding wrist strap

Connecting the MX480 Router to a Network for Out-of-Band Management

To connect the Routing Engine to a network for out-of-band management, connect an Ethernet cable with RJ-45 connectors to the ETHERNET port on the Routing Engine. To connect to the ETHERNET port on the Routing Engine:

  1. Turn off the power to the management device.
  2. Plug one end of the Ethernet cable (Figure 2 shows the connector) into the ETHERNET port on the Routing Engine. Figure 1 shows the port.
  3. Plug the other end of the cable into the network device.

Connecting the MX480 Router to a Management Console or Auxiliary Device

To use a system console to configure and manage the Routing Engine, connect it to the appropriate CONSOLE port on the Routing Engine. To use a laptop, modem, or other auxiliary device, connect it to the AUX port on the Routing Engine. Both ports accept a cable with an RJ-45 connector. To connect a device to the CONSOLE port and another device to the AUX port, you must supply two separate cables.

Note:

We no longer include a DB-9 to RJ-45 cable or a DB-9 to RJ-45 adapter with a CAT5E copper cable as part of the device package. If you require a console cable, you can order it separately with the part number JNP-CBL-RJ45-DB9 (DB-9 to RJ-45 adapter with a CAT5E copper cable).

To connect a management console or auxiliary device:

  1. Turn off the power to the console or auxiliary device.
  2. Plug the RJ-45 end of the serial cable (Figure 4 shows the connector) into the AUX port or CONSOLE port on the Routing Engine. Figure 3 shows the ports.
  3. Plug the female DB-9 end into the device's serial port.
    Note:

    For console devices, configure the serial port to the following values:

    • Baud rate—9600

    • Parity—N

    • Data bits—8

    • Stop bits—1

    • Flow control—none

Connecting the MX480 Router to an External Alarm-Reporting Device

To connect the router to external alarm-reporting devices, attach wires to the RED and YELLOW relay contacts on the craft interface. (See Figure 5.) A system condition that triggers the red or yellow alarm LED on the craft interface also activates the corresponding alarm relay contact.

The terminal blocks that plug into the alarm relay contacts are supplied with the router. They accept wire of any gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm2), which is not provided. Use the gauge of wire appropriate for the external device you are connecting.

To connect an external device to an alarm relay contact (see Figure 5):

  1. Prepare the required length of wire with gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm2).
  2. While the terminal block is not plugged into the relay contact, use a 2.5-mm flat-blade screwdriver to loosen the small screws on its side. With the small screws on its side facing left, insert wires into the slots in the front of the block based on the wiring for the external device. Tighten the screws to secure the wire.
  3. Plug the terminal block into the relay contact, and use a 2.5-mm flat-blade screwdriver to tighten the screws on the face of the block.
  4. Attach the other end of the wires to the external device.

To attach a reporting device for the other kind of alarm, repeat the procedure.

Connecting DPC, MPC, MIC, or PIC Cables to the MX480 Router

To connect the DPCs, MPCs, MICs, or PICs to the network (see Figure 6 and Figure 7):

  1. Have ready a length of the type of cable used by the component. For cable specifications, see the MX Series Interface Module Reference.
  2. Remove the rubber safety plug from the cable connector port.
    Laser 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 a transceiver emit laser light that can damage your eyes.

    CAUTION:

    Do not leave a fiber-optic transceiver uncovered, except when inserting or removing a cable. The safety cap keeps the port clean and protects your eyes from accidental exposure to laser light.

  3. Insert the cable connector into the cable connector port on the faceplate.
    Note:

    The XFP cages and optics on the components are industry standard parts that have limited tactile feedback for insertion of optics and fiber. You need to insert the optics and fiber firmly until the latch is securely in place.

  4. Arrange the cable to prevent it from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop.
    CAUTION:

    Avoid bending a fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

    CAUTION:

    Do not let fiber-optic cables hang free from the connector. Do not allow the fastened loops of a cable to dangle, which stresses the cable at the fastening point.

Connecting the Alarm Relay Wires to the MX480 Craft Interface

To connect the alarm relay wires between a router and an alarm-reporting device (see Figure 8):

  1. Prepare the required length of replacement wire with gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm2).
  2. Insert the replacement wires into the slots in the front of the block. Use a 2.5-mm flat-blade screwdriver to tighten the screws and secure the wire.
  3. Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD grounding point.
  4. Plug the terminal block into the relay contact, and use a 2.5-mm flat-blade screwdriver to tighten the screws on the face of the block.
  5. Attach the other end of the wires to the external device.
