Connecting the PTX3000 to External Devices

Connecting the PTX3000 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 or Routing and Control Board (RCB) for management and service operations (see Figure 1).

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

  1. To connect the PTX3000 to external devices, you need an electrostatic discharge (ESD) grounding wrist strap (provided in the accessory box).
  2. Attach an ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
    CAUTION:

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

  3. If necessary, turn off power to the console or auxiliary device.
  4. Plug one end of a copper cable with RJ-45 connectors into the CON or AUX port on the Control Board or RCB in slot CB0 (Figure 1).
  5. Attach the other end of the cable to the console or auxiliary device.
  6. Plug one end of another copper cable with RJ-45 connectors into the CON or AUX port on the Control Board or RCB in slot CB1.
  7. Attach the other end of the cable to the console or auxiliary device.

Connecting the PTX3000 to a Management Ethernet Device

To connect the management Ethernet ports on each Control Board or Routing and Control Board (RCB) to a network for management of the PTX3000, connect a UTP Category 5 Ethernet cable with an RJ-45 connector to the HOST/ETHERNET port on a Control Board, or the MGT port on an RCB.

Note:

For PTX3000 routers with two host subsystems, we recommend that you connect both host subsystems to a network. One cable is provided in the accessory box. To connect another cable to the management Ethernet ports on the second Control Board or RCB, you must provide an additional cable.

To connect a cable to a network device:

  1. To connect the PTX3000 to external devices, you need an electrostatic discharge (ESD) grounding wrist strap (provided in the accessory box).
  2. Attach an ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
    CAUTION:

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

  3. Plug one end of a UTP Category 5 Ethernet cable (Figure 2 shows the connector) into the management Ethernet port on the Control Board or RCB in slot CB0 (see Figure 3).
    Note:

    The management Ethernet port is labeled HOST/ETHERNET on a Control Board. The port is labeled MGT on an RCB.

  4. Plug the other end of the cable into the network device.
  5. Plug one end of another UTP Category 5 Ethernet cable into the management Ethernet port on the Control Board or RCB in slot CB1.
  6. Plug the other end of the cable into the network device.

Connecting the PTX3000 to an External Alarm-Reporting Device

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

  1. To connect the PTX3000 to external devices, you need:
    • 2.5-mm flat-blade (–) screwdriver for the alarm relay contacts

    • Electrostatic discharge (ESD) grounding wrist strap (an ESD grouding strap is provided in the accessory box)

  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point 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.

  3. Prepare the required length of wire with gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm2).
  4. 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), respectively.

  5. 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.
  6. Attach the other end of the wires to the external device.

Connecting PIC or IPLC Cables to the PTX3000

The PTX3000 supports PICs and IPLCs 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 the IPLCs to compatible PICs/MICs (see PTX Series IPLC Compatibility), or to other IPLCs, or to the optical inline amplifier (ILA).

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

  1. To connect the PTX3000 to external devices, you need the following:
    • The required length of the type of cable used by the PIC. See the PTX Series Interface Module Reference.

    • Number 1 Phillips (+) screwdriver to loosen the captive screws on the cable management system.

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

  2. Attach an ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
    CAUTION:

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

  3. If the PIC cable connector port is covered by a rubber safety plug, remove the plug. The IPLC ports have an attached cover for the connector.
    Laser Warning:

    Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cable. 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.

  4. Insert the cable connector into the cable connector port on the PIC or IPLC faceplate. See Figure 4 and Figure 5.
  5. Using a number 1 Phillips (+) screwdriver, loosen the two inner captive screws on the upper or lower cable management system. Move the cover of the upper cable management system up (Figure 6). Move the cover of the lower cable management system down (Figure 7).
  6. Arrange the cable in the cable management system to prevent it from dislodging or developing stress points (Figure 8). Secure the cable so that it is not supporting its own weight as it hangs to the floor.
    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.

  7. Move the cover of the upper cable management system down, and secure the two inner captive screws on the upper cable management system by using a number 1 Phillips (+) screwdriver. Move the cover of the lower cable management system up, and secure the two inner captive screws on the lower cable management system by using the screwdriver.
