    Replacing the T1600 Connections to Routing Engine Interface Ports

    The ports on the CIP connect the Routing Engine to external management devices (see Figure 1).

    To replace the cables that connect to the ports, perform the procedures described in the following topics:

    Replacing a T1600 Console or Auxiliary Cable

    1. Removing a T1600 Console or Auxiliary Cable
    2. Installing a T1600 Console or Auxiliary Cable

    Removing a T1600 Console or Auxiliary Cable

    To replace a serial cable connected 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 site ESD points on the chassis.
    2. Turn off the power to the console or auxiliary device.
    3. Unscrew the screws that secure the cable connector to the port, using a 2.5-mm flat-blade screwdriver if necessary.
    4. Pull the cable connector straight out of the port.
    5. Disconnect the cable from the console or auxiliary device.

    Installing a T1600 Console or Auxiliary Cable

    The AUXILIARY port and CONSOLE port on the CIP both accept an RS-232 (EIA-232_ serial cable with DB-9 connectors. For cable specifications, see T1600 Routing Engine Interface Cable and Wire Specifications.

    To connect 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 site ESD points on the chassis.
    2. Connect one end of the replacement cable into the appropriate CONSOLE or AUXILIARY port. The ports labeled HOST 0 connect to the Routing Engine in the upper Routing Engine slot (RE0), and the ports labeled HOST 1 connect to the Routing Engine in the lower Routing Engine slot (RE1).
    3. Using a 2.5-mm flat-blade screwdriver, tighten the screws on the connector.
    4. Plug the other end of the cable into the device's serial port.

    Replacing a T1600 Management Ethernet Cable

    To replace the management Ethernet cable:

    1. Press the tab on the connector and pull the connector straight out of the ETHERNET port. Figure 2 shows the connector.
    2. Disconnect the cable from the network device.
    3. Plug one end of the replacement cable into the appropriate ETHERNET port. The ports labeled HOST 0 connect to the Routing Engine in the upper Routing Engine slot (RE0), and the ports labeled HOST 1 connect to the Routing Engine in the lower Routing Engine slot (RE1).
    4. Plug the other end of the cable into the network device.

    Replacing the T1600 Alarm Relay Wires

    To connect the router to external alarm-reporting devices, attach wires to the RED ALARM and YELLOW ALARM relay contacts on the CIP. 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 replace the wires connecting to an alarm-reporting device:

    1. Disconnect the existing wire at the external device.
    2. Prepare the required length of replacement wire with gauge between 28 AWG and 14 AWG (0.08 and 2.08 mm2).
    3. Using a 2.5-mm flat-blade screwdriver, loosen the small screws on the face of the terminal block and remove the block from the relay contact.
    4. Using the 2.5-mm flat-blade screwdriver, loosen the small screws on the side of the terminal block. Remove existing wires from the slots in the front of the block and insert replacement wires. Tighten the screws to secure the wire.
    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.
