Replacing the T640 CIP

Removing a T640 CIP

The CIP is located to the left side of the FPC card cage, as shown in T640 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 8 lb (3.6 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 T640 Preventing Electrostatic Discharge Damage.
2. Disconnect any external devices connected to the CIP. For instructions, see Replacing the T640 Connections to 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 a T640 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.
