Removing and Installing Port Adapters
This chapter describes how to remove the DPT port adapter port adapter from supported platforms and also how to install a new or replacement port adapter. This chapter contains the following sections:

Port Adapter Removal and Installation
Installation Overview
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.
Handling Port Adapters
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 DPT port adapter on Cisco 7200 series, Cisco 7200 VXR, or Cisco uBR7246 routers.
Although Cisco 7500 series routers do support OIR, VIPs do not. To remove or install a port adapter on the VIP, first remove the VIP from the chassis, and then remove or install the port adapter.
Note As you disengage the port adapter from the router or switch, OIR administratively shuts down all active interfaces in the port adapter.
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.
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.
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 in the following illustrations.
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 Slot Divider
If you are installing a DPT port adapter in a Cisco 7200 series or Cisco 7200 VXR router that has two single-width port adapters installed, you need to perform the procedure shown in the "Cisco 7200 Series—Removing the Slot Divider" section. If you are installing a DPT port adapter in a Cisco uBR7246 router that has two single-width port adapters installed, you need to perform the procedure shown in the "Cisco uBR7200 Series—Removing the Slot Divider" section. If you are installing a DPT port adapter in a Cisco 7500 series router with a VIP that has two single-width port adapters installed, you need to perform the procedure shown in the "VIP—Removing the Slot Divider" section.
Cisco 7200 Series—Removing the Slot Divider
Cisco uBR7200 Series—Removing the Slot Divider
Step 1 Remove installed single-width port adapters from the slots on both sides of the port adapter slot divider.
Step 2 With one hand, raise the slot divider lever to unlock the slot divider from the chassis.
(See Figure 3-2.)

Step 3 With the slot divider lever still raised, use your other hand to pull the slot divider from the chassis.
(See Figure 3-3.)

Step 4 Store the slot divider in a location where you can retrieve it for use later.
Note The port adapter slot divider is available from Cisco Systems as a spare. Use Product Number MAS-72KSLOTDIV= when ordering a spare port adapter slot divider.
VIP—Removing the Slot Divider
Dual-width port adapters occupy both slots on a VIP. Before you can install a dual-width port adapter, you must first remove the slot divider that is located between the two slots. (See Figure 3-4.)
Figure 3-4 Location of VIP Slot Divider and Screws
Use the following procedure to remove the slot divider from a VIP:
Step 1 Attach an ESD-preventive wrist strap between you and an unpainted chassis surface.
Step 2 Remove the VIP from the router.
Step 3 Place the removed VIP on an antistatic mat or foam pad.
Step 4 Remove any installed modules or blanks from the slots on the VIP. To do this, use a number 1 Phillips screwdriver to remove the screw located at the rear of each slot.
•To locate this screw on dual-width modules, see the "Cisco 7500 Series Routers with VIP—Removing and Installing a Port Adapter" section.
•Use a number 1 Phillips screwdriver to remove the four slot divider screws that secure the slot divider to the VIP motherboard. (See Figure 3-4.)
Step 5 Remove the slot divider and store it (and the screws) in a location where you can retrieve it for use later.
Note If you need to reinstall the slot divider, place the slot divider in position on the VIP and secure it with the four Phillips screws.
Once the slot divider is removed, refer to the "Cisco 7500 Series Routers with VIP—Removing and Installing a Port Adapter" section, which describes the steps required to install or remove a dual-width module.
This completes the procedure for removing a port adapter slot divider from a Cisco 7200 series, Cisco 7200 VXR, Cisco uBR7200 series, or Cisco 7500 series router with VIP.
