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 port adapter 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 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

The Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco 7201 router, Cisco 7301 router, and Cisco 7401ASR router support the online insertion and removal (OIR) of all port adapters. Therefore, you do not have to power down routers when removing and replacing port adapters in these chassis.

The FlexWAN module, Cisco 7304 PCI port adapter carrier card, and VIP do not support OIR of individual port adapters. To remove or install port adapters on a FlexWAN module, Cisco 7304 PCI port adapter carrier card, or VIP, you must first remove the FlexWAN module, Cisco 7304 PCI port adapter carrier card, or VIP from the router and then remove or install the port adapters as required.


Note To prevent system problems, do not remove or install port adapters from a FlexWAN module, Cisco 7304 PCI port adapter carrier card, or VIP when the system is operating. To install or replace port adapters, first remove the FlexWAN module, Cisco 7304 PCI port adapter carrier card, or VIP from the router.



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



Tip 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.



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


Warnings and Cautions

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


Caution 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.


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 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.


Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first. Statement 1026


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. This section contains the following illustrations:

Note The steps in the "Cisco 7600 Series Routers—Removing and Installing a Port Adapter" section apply to Catalyst 6500 series switches and Cisco 7600 series routers.



Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the midplane with your hand or any metal tool, or you could shock yourself. Statement 181

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.

Connecting Interface Cables

The PA-MC-8TE1+ port adapter uses shielded twisted-pair cables with RJ-48C connectors to connect to a PBX or to the Public Switched Telephone Network (PSTN).

Shielded FTP (foil twisted-pair) cables with 120-ohm impedance are required to comply with CE marking requirements. These shielded cables are not available from Cisco Systems; they are available from outside commercial cable vendors.

To connect FTP cables with RJ-48C connectors to the PA-MC-8TE1+port adapter, proceed as follows:


Step 1 Attach the cable directly to one of the RJ-48C ports on the PA-MC-8TE1+ port adapter.

Step 2 Attach the network end of the cable to your external equipment.

Step 3 Repeat Step 1 and Step 2 for the other PA-MC-8TE1+ ports.

Note Port adapters have a handle attached, but this handle is not shown in Figure 3-3 to allow a full view of the detail on each port adapter's faceplate.



Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023



Warning Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of electric shock from lightning. Statement 1038



Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001



Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021
