Connecting the PTX5000 to External Devices

Tools and Parts Required to Connect the PTX5000 to External Devices

To connect the PTX5000 to external devices, you need the following tools and parts:

  • 2.5-mm flat-blade (–) screwdriver for the alarm relay contacts

  • Electrostatic discharge (ESD) grounding wrist strap (provided in the accessory kit)

Connecting the PTX5000 to a Management Console or Auxiliary Device

Attach one or more management console or auxiliary devices to the Routing Engine ports on each Control Board for management and service operations (see Figure 1).

To connect the cables to a management console or auxiliary device:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. If necessary, turn off the power to the console or auxiliary device.
  3. Plug one end of a copper cable with RJ-45 connectors into the CONSOLE or AUXILIARY port on the Control Board in slot CB0. This port connects to the Routing Engine installed into the Control Board in slot CB0.
  4. Attach the other end of the cable to the console or auxiliary device.
  5. Plug one end of another copper cable with RJ-45 connectors into the CONSOLE or AUXILIARY port on CB1. This port connects to the Routing Engine installed into the control in slot CB1.
  6. Attach the other end of the cable to the console or auxiliary device.

Connecting the PTX5000 to a Management Ethernet Device

To connect the Routing Engines in a PTX5000 to a network for management of the PTX5000, connect a UTP Category 5 Ethernet cable with an RJ-45 connector to the HOST/ETHERNET port on a Control Board.

Note:

For PTX5000 routers with two host subsystems, we recommend that you connect both Control Boards to a network. One cable is provided in the accessory box. To connect another cable to the HOST/ETHERNET port on the other Control Board, you must provide an additional cable.

To connect a cable to a network device:

  1. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
    CAUTION:

    During the initial installation before the chassis is grounded, you must connect to an approved site ESD point. See the instructions for your site.

  2. Plug one end of a UTP Category 5 Ethernet cable (Figure 2 shows the connector) into the HOST/ETHERNET port on the Control Board in slot CB0 (see Figure 3). This port connects to the Routing Engine installed into the Control Board in slot CB0.
  3. Plug the other end of the cable into the network device.
  4. Plug one end of another UTP Category 5 Ethernet cable into the HOST/ETHERNET port on the Control Board in slot CB1. This port connects to the Routing Engine installed into the Control Board in slot CB1.
  5. Plug the other end of the cable into the network device.

Connecting the PTX5000 to an External Alarm-Reporting Device

To connect an external device to an alarm relay contact on the craft interface:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
    CAUTION:

    During the initial installation before the chassis is grounded, you must connect to an approved site ESD point. See the instructions for your site.

  2. Prepare the required length of wire with gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm2).
  3. 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. Connect the major and minor alarm circuits to the NO (normally open) pins on the alarm connectors. Tighten the screws to secure the wire.
    Note:

    The top, middle, and bottom slots correspond to NC (normally closed), C (common), and NO (normally open).

  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.

Connecting the PTX5000 to an External Clocking Device

To connect the PTX5000 to one or two external clocking devices, connect a cable with RJ-48 connectors to the BITS A or BITS B port on the CCG.

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. Plug one end of the cable into the BITS A port on the CCG.
  3. Plug the other end of the cable into the T1 external clocking device.
  4. Repeat the procedure for the BITS B port on the CCG.
  5. Verify that the LINK LED for the port is lit steadily green and that the FAULT LED is not lit.
  6. Configure the port. See the synchronization statement for PTX Series routers in the Junos OS Administration Library.
  7. Issue the show chassis synchronization extensive command to check the status of the port.

Connecting PIC Cables to the PTX5000

The PTX5000 supports PICs that use various kinds of network cable, including multimode and single-mode fiber-optic cable. For information about the type of cable used by each PIC, see the PTX Series Interface Module Reference.

You connect PICs to the network by plugging in network cable. To connect cable to the PICs (see Figure 4):

  1. Have ready a length of the type of cable used by the PIC. See the PTX Series Interface Module Reference.
  2. If the PIC cable connector port is covered by a rubber safety plug, remove the plug.
    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 cable 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 cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

  3. Insert the cable connector into the cable connector port on the PIC faceplate.
  4. Arrange the cable in the cable management system 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 in the cable management system. Placing fasteners on the loop helps to maintain its shape.
    CAUTION:

    Avoid bending 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 cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.
