Removing and Installing Port Adapters
This chapter describes how to remove the PA-VXA, PA-VXB, and PA-VXC port adapters 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
•Connecting Interface Cables
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.Handling Port Adapters
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
Caution Always handle the VIP by the carrier edges and handle; never touch the VIP components or connector pins. (See Figure 3-2.)Figure 3-2 Handling the VIP—Horizontal Orientation Shown
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-VXA, PA-VXB, or PA-VXC port adapter in Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco 7301 routers, and Cisco 7401ASR routers.
Note The Cisco 7301 router is currently supported by the PA-VXB-2TE1+(=) and the PA-VXC-2TE1(=) port adapters only.
Note The Cisco 7401ASR router is currently supported by the PA-VXB-2TE1+(=) and the PA-VXC-2TE1+(=) port adapters only.
Although the Cisco 7500 series routers support online insertion and removal of the VIP motherboard, individual port adapters cannot be inserted or removed from a VIP without first removing it from the chassis. To install a new port adapter in a Cisco 7500 series router, you must first install it on a VIP motherboard.
Caution To prevent system problems, do not remove the PA-VXA, PA-VXB, or PA-VXC from the VIP motherboard. To install or replace these port adapters, first remove the 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 module while traffic is flowing through the ports can cause system disruption. Once the module is inserted, the ports can be brought back up.
Note As you disengage the module from the router or switch, online insertion and removal (OIR) administratively shuts down all active interfaces in the module.
OIR allows you to install and replace modules 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 module 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 module in a supported platform, refer to the "Port Adapter Removal and Installation" section.
Each module 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 module. The system assesses the signals it receives and the order in which it receives them to determine if a module 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 module, the longest pins make contact with the module 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 module, the pins send signals to notify the system of changes. The router then perfoms 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 module 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 module type is reinserted into a slot, its ports are configured and brought online up to the port count of the originally installed module 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 or VIP motherboard 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 or VIP motherboard it is installed on is not completely seated in the midplane or backplane. Carefully pull the card halfway out of the slot, reinsert it, and move the port adapter lever or other mechanism to the locked position.

Connecting Interface Cables
The PA-VXA, PA-VXB, and PA-VXC port adapters use shielded twisted-pair cables with RJ-45 connectors to connect to a PBX or to the PSTN.
Shielded cables (foil twisted-pair [FTP]) 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 shielded twisted-pair cables with RJ-45 connectors to the PA-VXA, PA-VXB, or PA-VXC port adapters, proceed as follows:
Step 1 Attach the cable directly to one of the RJ-45 ports on the PA-VXA, PA-VXB, or PA-VXC 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-VXB or PA-VXC port.
Figure 3-3 Connecting the PA-VXC Twisted-Pair Cable with RJ-45 Connector
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 faceplate.
