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.
When powering off the router, wait a minimum of 30 seconds before powering it on again.
Always handle the port adapter by the carrier edges and handle; never touch the port adapter components or connector pins. (See
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-2FE 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 in the Cisco 7304 router or Cisco 7500 series routers, you must first remove the Cisco 7304 PCI port adapter carrier card or VIP from the router and then install or replace port adapters as required. If a blank port adapter is installed in 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 router and then remove the blank port adapter.
To prevent system problems, do not remove port adapters from the Cisco 7304 PCI port adapter carrier card or Cisco 7500 VIP motherboard or attempt to install other port adapters when the system is operating.
OIR allows you to install and replace port adapters and service adapters (carrier cards and VIPs) 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.
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.
The following is a functional description of OIR for background information only; for specific procedures for installing and replacing a PA-2FE in a supported platform, refer to the "Port Adapter Removal and Installation" section.
Each PA-2FE 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 "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.
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.
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.
When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the Cisco 7304 PCI port adapter carrier card.
Note If the Cisco 7304 PCI port adapter carrier card is still in the router, you must remove the port adapter carrier card before removing a port adapter.
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 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 2 Ensure that the cables are disconnected from the port adapter before removing the Cisco 7304 PCI port adapter carrier card from the chassis.
Step 3 Grasp the handle of the port adapter and pull the port adapter from 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 a PA-2FE RJ-45 or SC Cable
To continue your PA-2FE port adapter installation, you must install the port adapter's interface cables. The following instructions apply to all supported platforms.
RJ-45 and SC-type fiber-optic cables are not available from Cisco; they are available from commercial cable vendors.
Use the following procedure to connect RJ-45 or SC cables:
Step 1 If you have RJ-45 connections (PA-2FE-TX), attach the Category 5 unshielded twisted-pair (UTP) cable directly to an RJ-45 port on the PA-2FE-TX. (See Figure 3-3.) The PA-2FE is an end-station device and not a repeater. You must connect the PA-2FE to a transceiver, switch, hub, repeater, DTE, or back-to-back to another 10/100-Mbps Fast Ethernet adapter.
If you have SC connections (PA-2FE-FX), attach the cable directly to an SC port on the PA-2FE-FX. (See Figure 3-4.) Use either one duplex SC connector or two simplex SC connectors, and observe the correct relationship between the receive (RX) and transmit (TX) ports on the PA-2FE-FX and your repeater.
Note Port adapters have a handle attached, but this handle is not shown to allow a full detailed view of each port adapter's faceplate.
Step 2 Attach the network end of your RJ-45 or SC-type cable to your 10/100BASE-T transceiver, switch, hub, repeater, DTE, or other external 10/100BASE-T equipment.
