VIP2 and the PA-MC-2T3+

This chapter provides information on the PA-MC-2T3+ port adapter and its use on the VIP2 in Cisco 7000 series and Cisco 7500 series routers. This chapter contains the following sections:

Installation Overview

The PA-MC-2T3+ port adapter is used on the VIP2 and can be installed in either port adapter slot 0 or port adapter slot 1.

Note Port adapters have a handle attached, but this handle is not shown to allow a detailed view on each port adapter faceplate.

Figure 3-1 shows two PA-MC-2T3+ port adapters installed in port adapter slots 0 and 1 on a VIP2-50.

Removing a Port Adapter

This section provides the standard procedures for removing a port adapter on the VIP2.

Depending on the circumstances, you might need to install a new port adapter on a VIP2 motherboard or replace a failed port adapter in the field. In either case, you need a number 1 Phillips screwdriver, an antistatic mat onto which you can place the removed interface processor, and an antistatic container into which you can place a failed port adapter for shipment back to the factory.

Caution To prevent system problems, do not remove port adapters from the VIP2 motherboard or attempt to install other port adapters on the VIP2 motherboard while the system is operating. To install or replace port adapters, first remove the VIP2 from its interface processor slot.

Note Each port adapter circuit board is mounted to a metal carrier and is sensitive to ESD damage. The following procedures should be performed by a Cisco-certified service provider only. Although the VIP2 supports online insertion and removal (OIR), individual port adapters do not. To replace port adapters, you must first remove the VIP2 from the chassis and then install or replace port adapters as required. If a blank port adapter is installed on the VIP2 in which you want to install a new port adapter, you must first remove the VIP2 from the chassis, and then remove the blank port adapter.

When only one port adapter is installed on a VIP2, a blank port adapter must fill the empty slot to allow the VIP2 and router chassis to conform to electromagnetic interference (EMI) emissions requirements, and to permit proper airflow through the chassis. If you plan to install a new port adapter, you must first remove the blank port adapter.

Following is the standard procedure for removing and replacing any type of port adapter on the VIP2:

Step 1 Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.

Step 2 For a new port adapter installation or a port adapter replacement, disconnect all interface cables from the ports on the front of the port adapter. You can remove VIP2s with cables attached; however, we do not recommend it.

Step 3 Remove the VIP2 from the chassis. To do so, follow the steps in the section "Removing a VIP2" in the configuration note Second-Generation Versatile Interface Processor (VIP2) Installation and Configuration that shipped with your VIP2.

Step 4 Place the removed VIP2 on an antistatic mat.

Step 5 Locate the screw at the rear of the port adapter (or blank port adapter) to be replaced. (See Figure 3-2.) This screw secures the port adapter (or blank port adapter) to its slot.

Step 6 Remove the screw that secures the port adapter (or blank port adapter).

Step 7 With the screw removed, grasp the handle on the front of the port adapter (or blank port adapter) and carefully pull it out of its slot, away from the edge connector at the rear of the slot. (See Figure 3-3.)

Step 8 If you removed a port adapter, place it in an antistatic container for safe storage or shipment back to the factory. If you removed a blank port adapter, no special handling is required; store the blank port adapter for potential future use.

This completes the procedure for removing a port adapter from a VIP2.

Installing a Port Adapter

This section provides the standard procedures for installing a port adapter on the VIP2.

Step 1 Remove the new port adapter from its antistatic container and position it at the opening of the slot so that the leading edges of the carrier are between the upper and lower slot edges. (See Figure 3-4.)

Step 2 Carefully align the port adapter carrier between the upper and lower edges of the port adapter slot, as shown in Figure 3-4.

Caution To prevent jamming the carrier between the upper and lower edges of the port adapter slot, and to ensure that the edge connector at the rear of the port adapter mates with the connector at the rear of the port adapter slot, make certain that the carrier is positioned correctly, as shown in the cutaway in Figure 3-4.

Step 3 Carefully slide the new port adapter into the port adapter slot until the connector on the port adapter is completely seated in the connector on the motherboard.

Step 4 Install the screw in the rear of the port adapter slot. (See Figure 3-2 for its location.) Do not overtighten this screw.

Step 5 Replace the VIP2 in the chassis. To do so, follow the steps in the section "Installing a VIP2" in the configuration note Second-Generation Versatile Interface Processor (VIP2) Installation and Configuration that shipped with your VIP2.

Step 6 If they have been disconnected, reconnect the interface cables to the interface processor.

This completes the procedure for installing a new port adapter or replacing a port adapter on a VIP2. Proceed to the "Installing the PA-MC-2T3+ Interface Cables" chapter to connect the necessary cables to your port adapter.
