Removing an M320 CIP

The CIP is located to the left side of the FPC card cage, as shown in M320 Chassis Description. It houses the Routing Engine interface ports, which accept connections to external management and alarm-reporting devices.

The CIP is hot-pluggable. It weighs approximately 6.8 lb (3.1 kg). When the CIP is removed, you cannot control or communicate with the router using an external device.

To remove the CIP (see Figure 1):

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. For more information about ESD, see Preventing Electrostatic Discharge Damage to an M Series, MX Series, or T Series Router.
2. Disconnect any external devices connected to the CIP. For instructions, see Replacing Connections to the M320 Routing Engine Interface Ports.
3. Loosen the captive screws at the top and bottom of the CIP faceplate.
4. Grasp the handle on the CIP faceplate, and carefully pull the CIP straight out of the chassis.

   Caution: Be sure to slide the CIP straight within the slot to avoid damaging the connector pins on the front of the midplane.

Installing an M320 CIP

To install the CIP (see Figure 2):

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. Grasp the CIP handle with one hand and hold the bottom edge of the CIP with the other hand to support its weight.

   Note: The components on the CIP are on the left side of the board, unlike the components of an FPC, which are on the right side. Verify that the components are on the left before inserting the CIP.

3. Insert the CIP into the leftmost slot of the FPC card cage, carefully aligning the top and bottom of the CIP with the guides in the card cage.
4. Carefully push the CIP straight into the chassis until it contacts the midplane.
5. Tighten the screws at the top and bottom of the CIP faceplate.
6. Reattach any external devices connected to the CIP.

   Caution: Be sure to slide the CIP straight within the slot to avoid damaging the connector pins on the front of the midplane.

7. To verify that the CIP is installed correctly, plug an Ethernet cable into the Ethernet port on the CIP. If the host module is operational, the ACTIVE LED blinks to indicate Ethernet activity. If you can run the CLI, the CIP is installed correctly.

Replacing the M320 Connections to Routing Engine Interface Ports

The ports on the CIP connect the Routing Engine to external management devices (see Figure 3).

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

• Replacing the M320 Management Ethernet Cables
• Removing an M320 Console or Auxiliary Cable
• Installing an M320 Console or Auxiliary Cable
• Replacing the M320 Alarm Relay Wires

Replacing the M320 Management Ethernet Cables

To replace the management Ethernet cables:

1. Press the tab on the connector and pull the connector straight out of the ETHERNET port. Figure 4 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.

Removing an M320 Console or Auxiliary Cable

To replace a serial cable connected to a management console or auxiliary device, see Figure 5:

1. Turn off the power to the console or auxiliary device.
2. Unscrew the screws that secure the cable connector to the port, using a 2.5-mm flat-blade screwdriver if necessary.
3. Pull the cable connector straight out of the port.
4. Disconnect the cable from the console or auxiliary device.

Installing an M320 Console or Auxiliary Cable

To install a console or auxiliary cable:

1. Turn off the power to the console or auxiliary device.
2. Connect one end (shown in Figure 6) 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).
3. Using a 2.5-mm flat-blade screwdriver, tighten the screws on the connector.
4. Attach the other end of the cable to the console or auxiliary device.

5. 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):

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.
