VIP2 and the PA-F/FD

This chapter provides information on the PA-F/FD-SM and PA-F/FD-MM full-duplex FDDI port adapters and their use on the VIP2 in Cisco 7000 series and Cisco 7500 series routers. This chapter contains the following sections:

Installation Overview

The PA-F/FD-MM and the PA-F/FD-SM used on the VIP2 can be installed in either port adapter slot 0 or port adapter slot 1.

The PA-F/FD-MM uses multimode MIC optical-fiber interface connections, and the PA-F/FD-SM uses single-mode SC-type optical-fiber interface connections. Both the PA-F/FD-MM and the PA-F/FD-SM have optical bypass switching capability in the form of a mini-DIN connector.

Figure 3-1 shows two PA-F/FD-SM port adapters installed in slot 0 and slot 1 on a VIP2-15 or VIP2-40.

Note Port adapters have a handle attached, but this handle is not shown to allow a full view of detail on each port adapter's faceplate.

Removing a Port Adapter

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 the following tools:

Number 1 Phillips screwdriver
Antistatic mat
Antistatic container

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. Each port adapter has one Phillips-head screw that secures it to its port adapter slot. We strongly recommend that the following procedures be performed by a Cisco-certified service provider; however, this is not a requirement.

Although the VIP2 supports online insertion and removal, 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.

Caution
To prevent interface reconfiguration requirements, you should replace a port adapter with the same type of port adapter you removed, but this is not a requirement.

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 allow proper airflow across the port adapters.

To remove any type of port adapter from a VIP2, follow these steps:

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

Note

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

Step 3 Remove the VIP2 from the system. (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.) Place the removed VIP2 on an antistatic mat.

Step 4 Locate the screw at the rear of the port adapter (or blank port adapter) to be replaced. (See Figure 3-5.) This screw secures the port adapter (or blank port adapter) to its slot.

Figure 3-5: Location of Port Adapter Screw

Step 5 Remove the screw that secures the port adapter (or blank port adapter).

Step 6 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 3-6.)

Step 7 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; however, store the blank port adapter for potential future use.

Installing a Port Adapter

To install any type of port adapter on a VIP2, follow these steps:

Step 1 Remove the new port adapter from its antistatic container and position it at the opening of the slot. (See Figure 3-6.)

Step 2 Carefully align the port adapter carrier between the upper and the lower edges of the slot, as shown in the cutaway in Figure 3-6.

Figure 3-7: Aligning a Port Adapter in a Port Adapter Slot

Caution
To prevent jamming the carrier between the upper and the lower edges of the port adapter slot, and to ensure that the edge connector at the rear of the port adapter seats in the connector at the rear of the port adapter slot, make certain that the leading edges of the carrier are between the upper and the lower slot edges, as shown in the cutaway in Figure 3-6.

Caution
To ensure a positive ground attachment between the port adapter carrier and the VIP2 motherboard and port adapter slot, and to ensure that the connectors at the rear of the port adapter and slot seat properly, the carrier must be between the upper and the lower slot edges.

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 Replace the screw in the rear of the port adapter slot. (See Figure 3-5 for the screw location.) Do not overtighten this screw.

Step 5 Reinstall the VIP2 in the system. (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.)

This completes the procedure for installing a new port adapter or replacing a port adapter on a VIP2. To attach the necessary cables, proceed to "Attaching the PA-F/FD Port Adapter Cables."
