The router uses the following types of FRUs: · Hot-removable and hot-insertable FRUs--You can remove and replace these components without powering off the router or disrupting the routing functions. Hot-pluggable FRUs--You can remove and replace these components without powering down the router, but the routing functions of the system are interrupted when the component is removed. · If the router contains a redundant host subsystem, the Control Board (T-CB), and the Routing Engine are hot-removable and hot-insertable. Before you replace a T-CB or Routing Engine, you must take the host subsystem offline. Table 22 on page 138 lists the FRUs for the T320 Core router.

It houses the Routing Engine interface ports, which accept connections to external management and alarm-reporting devices. When the CIP is removed, you cannot control or communicate with the router using an external device. To remove the CIP, (see Figure 63 on page 140): 1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. 2. 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. Figure 63: Removing the CIP 140 Copyright © 2010, Juniper Networks, Inc. Chapter 14: Replacing the T320 Router Hardware Components Installing the T320 CIP To install the CIP (see Figure 64 on page 142): 1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the 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. 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. [. . . ] Pack the router or component for shipment.
