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

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-MC-2E1 and PA-MC-8E1 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 Catalyst RSM/VIP2, Catalyst 6000 family FlexWAN module, 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 Catalyst RSM/VIP2, Catalyst 6000 family FlexWAN module, 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 Catalyst RSM/VIP2, Catalyst 6000 family FlexWAN module, Cisco 7304 PCI port adapter carrier card, or VIP on which you want to install a new port adapter, you must first remove the Catalyst RSM/VIP2, Catalyst 6000 family FlexWAN module, 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 Catalyst RSM/VIP2, Catalyst 6000 family FlexWAN module, 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 Catalyst RSM/VIP2, Catalyst 6000 family FlexWAN module, Cisco 7304 PCI port adapter carrier card, or VIP from its interface processor slot.

It is wise to gracefully shut down the system before removing a port adapter that has active traffic moving through it. Removing a port adapter while traffic is flowing through the ports can cause system disruption. Once the port adapter is inserted, the ports can be brought back up.


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


OIR allows you to install and replace port adapters while the router is operating; you do not need to notify the software or shut down the system power, although you should not run traffic through the port adapter you are removing while it is being removed. OIR is a method that is seamless to end users on the network, maintains all routing information, and preserves sessions.

The following is a functional description of OIR for background information only; for specific procedures for installing and replacing a port adapter in a supported platform, refer to the "Port Adapter Removal and Installation" section.

Each port adapter has a bus connector that connects it to the router. The connector has a set of tiered pins in three lengths that send specific signals to the system as they make contact with the port adapter. The system assesses the signals it receives and the order in which it receives them to determine if a port adapter is being removed from or introduced to the system. From these signals, the system determines whether to reinitialize a new interface or to shut down a disconnected interface.

Specifically, when you insert a port adapter, the longest pins make contact with the port adapter first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them.

When you remove or insert a port adapter, the pins send signals to notify the system of changes. The router then performs the following procedure:

1. Rapidly scans the system for configuration changes.

2. Initializes newly inserted port adapters or administratively shuts down any vacant interfaces.

3. Brings all previously configured interfaces on the port adapter back to their previously installed state. Any newly inserted interface is put in the administratively shutdown state, as if it was present (but not configured) at boot time. If a similar port adapter type is reinserted into a slot, its ports are configured and brought online up to the port count of the originally installed port adapter of that type.


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.


Note 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.



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 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.

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.

Connecting a Network Interface Cable

To continue your multichannel E1/PRI port adapter installation, you must install the port adapter interface cables. The following instructions apply to all supported platforms.

On a single multichannel E1/PRI port adapter, you can use up to two (PA-MC-2E1) or eight (PA-MC-8E1) RJ-48C connections. RJ-48C shielded cables are not available from Cisco Systems; they are available from outside commercial cable vendors.


Note The Catalyst RSM/VIP2 and the Catalyst 6000 family FlexWAN module support only the PA-MC-8E1 port adapter.


Connect RJ-48C shielded cables to the PA-MC-28E1 or PA-MC-8E1 port adapter using this procedure:


Step 1 Attach the Category 3 or 5 unshielded twisted-pair (UTP) cable directly to one of the RJ-48C ports on the multichannel E1/PRI port adapter.


Note To meet VCCI Class II EMI requirements, you must use foil twisted pair (FTP) cables.


Step 2 Attach the network end of your RJ-48C shielded cable to your external equipment.

Step 3 Repeat Step 1 and Step 2 for each of the remaining interfaces you want to install.


Verifying the Port Adapter Connection

Verify that the multichannel E1/PRI port adapter is connected correctly using this procedure:


Step 1 While the system reinitializes each interface, observe the console display messages and verify that the system discovers the PA-MC-2E1 or PA-MC-8E1 port adapter. The system should recognize the PA-MC-2E1 or PA-MC-8E1 port adapter interfaces but leave them configured as down.

Step 2 When the reinitialization is complete, verify that the enabled LED on the multichannel E1/PRI port adapter is on and remains on. If the LED does stay on, proceed to Step 5. If the enabled LED does not stay on, proceed to the next step.

Step 3 If the enabled LED on the multichannel E1/PRI port adapter fails to go on, suspect that the multichannel E1/PRI port adapter board connector is not fully seated in the backplane. Reinsert the port adapter until the connector is completely mated with the backplane. After the system reinitializes the interfaces, the enabled LED on the multichannel E1/PRI port adapter should go on. If the enabled LED goes on, proceed to Step 5. If the enabled LED does not go on, proceed to the next step.

Step 4 If the enabled LED still fails to go on, remove the multichannel E1/PRI port adapter and try installing it in another available port adapter slot.

If the enabled LED goes on when the multichannel E1/PRI port adapter is installed in the new slot, suspect a failed backplane port in the original port adapter slot.

If the enabled LED still fails to go on, but other LEDs on the multichannel E1/PRI port adapter go on, indicating activity, proceed to Step 5 to resume the installation checkout and suspect that the enabled LED on the multichannel E1/PRI port adapter has failed.

If no LEDs on the multichannel E1/PRI port adapter go on, suspect that the multichannel E1/PRI port adapter is faulty. Do not proceed with the installation. Contact a service representative to report the faulty equipment and obtain further instructions.

Step 5 Use the show interfaces command to verify the status of the multichannel E1/PRI port adapter interfaces. (If the interfaces are not configured, you must use the procedures in the "Configuring the Interfaces" section on page 4-2.)


This completes the port adapter cable installation. Proceed to Chapter 4, "Configuring the PA-MC-2E1 and PA-MC-8E1."
