Removing and Installing Port Adapters

This chapter describes how to remove the PA-4E1G port adapter from supported platforms and also how to install a new or replacement port adapter. This chapter contains the following sections:

•Handling Port Adapters

•Online Insertion and Removal

•Warnings and Cautions

•Port Adapter Removal and Installation

•Installing Interface Cables

Handling Port Adapters

Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage.

Note When a slot is not in use, a blank port adapter must fill the empty slot to allow the router or switch to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the installed port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove the blank port adapter.

Caution When powering off the router, wait a minimum of 30 seconds before powering it on again.

Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter components or connector pins. (See Figure 3-1.)

Figure 3-1 Handling a Port Adapter

Online Insertion and Removal

Several platforms support online insertion and removal (OIR) of port adapters; therefore, you do not have to power down routers when removing and replacing a PA-4E1G in the Cisco 7100 series routers, Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco uBR7200 series routers, Cisco 7201 router, Cisco 7301 router, or Cisco 7401ASR router.

Although the Cisco 7304 PCI port adapter carrier card and VIP support OIR, individual port adapters do not. To replace port adapters, you must first remove the Cisco 7304 PCI port adapter carrier card or VIP from the chassis and then install or replace port adapters as required. If a blank port adapter is installed on the Cisco 7304 PCI port adapter carrier card or VIP on which you want to install a new port adapter, you must first remove the Cisco 7304 PCI port adapter carrier card or VIP from the chassis and then remove the blank port adapter.

Caution To prevent system problems, do not remove port adapters from the Cisco 7304 PCI port adapter carrier card or VIP or attempt to install other port adapters on the motherboard when the system is operating. To install or replace port adapters, first remove the Cisco 7304 PCI port adapter carrier card or VIP from its interface processor slot.

Note As you disengage the port adapter from the router or switch, OIR administratively shuts down all active interfaces in the port adapter.

Warnings and Cautions

Observe the following warnings and cautions when installing or removing port adapters:

•Do not slide a port adapter all the way into the slot until you have connected all required cables. Trying to do so disrupts normal operation of the router or switch.

•If a port adapter lever or other retaining mechanism does not move to the locked position, the port adapter is not completely seated in the midplane. Carefully pull the port adapter halfway out of the slot, reinsert it, and move the port adapter lever or other mechanism to the locked position.

•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 mates with the connection at the rear of the port adapter slot, make certain that the carrier is positioned correctly, as shown in the cutaway illustrations in the "Port Adapter Removal and Installation" section.

Note Before you begin installation, read Chapter 2, "Preparing for Installation," for a list of parts and tools required for installation.

Warning When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the card. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the midplane or backplane with your hand or any metal tool, or you could shock yourself.

Port Adapter Removal and Installation

In this section, the illustrations that follow give step-by-step instructions on how to remove and install port adapters. Although the procedures may refer to a particular type of port adapter, the steps are the same for installing and removing all types of port adapters.

Cisco 7304 PCI Port Adapter Carrier Card—Removing and Installing a Port Adapter

You can install one single-width port adapter in a Cisco 7304 PCI Port Adapter Carrier Card. This section provides step-by-step instructions for removing and installing a port adapter in a Cisco 7304 PCI Port Adapter Carrier Card.

Warning When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the Cisco 7304 PCI Port Adapter Carrier Card. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the midplane or backplane with your hand or any metal tool, or you could shock yourself.

To remove and install a port adapter in a Cisco 7304 PCI Port Adapter Carrier Card, refer to Figure 3-2 and do the following:

Step 1 If the Cisco 7304 PCI Port Adapter Carrier Card is still in the router, you must remove the Cisco 7304 PCI Port Adapter Carrier Card before removing a port adapter.

Step 2 To remove the port adapter from the Cisco 7304 PCI Port Adapter Carrier Card, turn the port adapter lock from its locked and horizontal position shown in A of Figure 3-2 to its unlocked and vertical position shown in B of Figure 3-2.

Step 3 Grasp the handle of the port adapter and pull the port adapter from the Cisco 7304 PCI Port Adapter Carrier Card. (You have already disconnected the cables from the port adapter when removing the Cisco 7304 PCI Port Adapter Carrier Card).

Step 4 To insert the port adapter in the Cisco 7304 PCI Port Adapter Carrier Card, locate the guide rails inside the Cisco 7304 PCI Port Adapter Carrier Card that hold the port adapter in place. They are at the top left and top right of the port adapter slot and are recessed about an inch, as shown in C of Figure 3-2.

Step 5 Carefully slide the port adapter in the Cisco 7304 PCI Port Adapter Carrier Card until the port adapter makes contact with the port adapter interface connector. When fully seated, the port adapter front panel should be flush with the face of the Cisco 7304 PCI Port Adapter Carrier Card.

Step 6 After the port adapter is properly seated, turn the port adapter lock to its locked and horizontal position, as shown in A of Figure 3-2.

Figure 3-2 illustrates how to remove and install a port adapter in a Cisco 7304 PCI Port Adapter Carrier Card.

Installing Interface Cables

To continue your PA-4E1G installation, you must install the port adapter cables. The instructions that follow apply to all supported platforms.

Use the following procedure to connect cables to the PA-4E1G in unbalanced mode:

Step 1 Attach the DB-15 end of a 75-ohm, unbalanced coaxial cable with BNC connector to the first DB-15 port you plan to use on the unbalanced, 75-ohm PA-4E1G.

Step 2 Attach the network end of the 75-ohm, unbalanced coaxial cable to your external E1-G.703/G.704 equipment.

Step 3 Repeat Steps 1 and 2 for each additional interface you plan to use on the port adapter.

Use the following procedure to connect cables to the PA-4E1G in balanced mode:

Step 1 Attach the DB-15 end of one of the following types of cables to the first DB-15 port you plan to use on the balanced, 120-ohm PA-4E1G (see Figure 3-3):

•Balanced (120-ohm) cable with an RJ-45 connection at the network end

•Balanced (120-ohm) cable with twinaxial connectors and cables at the network end

•Balanced (120-ohm) cable with DB-15 connectors on both ends

Step 2 Attach the network end of the 120-ohm, balanced cable to your external E1-G.703/G.704 equipment.

Step 3 Repeat Steps 1 and 2 for each additional interface you plan to use on the port adapter.

Figure 3-3 Connecting a PA-4E1G 120-Ohm DB-15 Cable—Front View (Shown Without Handle)

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.

When attaching the cable receptacle on the PA-4E1G, use the cable-management bracket that shipped with your router for extra strain relief.

This completes the procedure for attaching a balanced or unbalanced cable to the PA-4E1G. Proceed to Chapter 4, "Configuring the PA-4E1G."
