Replacing the M320 Connections to Routing Engine Interface Ports
The ports on the CIP connect the Routing Engine to external management devices (see Figure 1).
Figure 1: Routing Engine Interface Ports and Alarm Relay Contacts
To replace the cables that connect to the ports, perform the procedures described in the following topics:
Replacing the M320 Management Ethernet Cables
To replace the management Ethernet cables:
- Press the tab on the connector and pull the connector straight out of the ETHERNET port. Figure 2 shows the connector.
- Disconnect the cable from the network device.
- 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).
- Plug the other end of the cable into the network device.

Removing an M320 Console or Auxiliary Cable
To replace a serial cable connected to a management console or auxiliary device, see Figure 3:
- Turn off the power to the console or auxiliary device.
- Unscrew the screws that secure the cable connector to the port, using a 2.5-mm flat-blade screwdriver if necessary.
- Pull the cable connector straight out of the port.
- Disconnect the cable from the console or auxiliary device.

Installing an M320 Console or Auxiliary Cable
To install a console or auxiliary cable:
- Turn off the power to the console or auxiliary device.
- Connect one end (shown in Figure 4) of the replacement serial cable into the appropriate CONSOLE or AUX port. The external device ports on the CIP. 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).
- Using a 2.5-mm flat-blade screwdriver, tighten the screws on the connector.
- Attach the other end of the cable to the console
or auxiliary device.

- Connect the other end of the serial cable into the serial port on the console or auxiliary device.
Replacing the M320 Alarm Relay Wires
To connect the router to external alarm-reporting devices, attach wires to the RED and YELLOW 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 (see Replacing Connections to the M320 Routing Engine Interface Ports):
- Disconnect the existing wire at the external device.
- Prepare the required length of replacement wire with gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm2).
- 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.
- 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.
- 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.
- Attach the other end of the wires to the external device.
