This chapter describes how to remove the CSA from supported platforms and also how to install a new or replacement service adapter. This chapter contains the following sections:
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 Always handle the port or service adapter by the carrier edges and handle; never touch the port adapter components or connector pins. (See Figure 3-1.) |
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 CSA on Cisco 7100 series routers, Cisco 7200 series routers, or Cisco uBR7200 series routers.
Although the VIP2 supports online insertion and removal, individual service and port adapters do not. To replace service and port adapters, you must first remove the VIP2 from the chassis and then install or replace service or port adapters as required. If a blank port adapter is installed on the VIP2 on which you want to install a new service or port adapter, you must first remove the VIP2 or from the chassis and then remove the blank port adapter.
|
Caution To prevent system problems, do not remove service or port adapters from the VIP2 motherboard or attempt to install other service or port adapters on the motherboard when the system is operating. To install or replace service or port adapters, first remove the VIP2 or from its interface processor slot. |
|
Note As you disengage the service or port adapter from the router or switch, online insertion and removal (OIR) administratively shuts down all active interfaces in the service or port adapter. |
|
Note Before you begin installation, read "Preparing for Installation," for a list of parts and tools required for installation. |
Observe the following warnings and cautions when installing or removing service or port adapters.
|
Caution Do not slide a service or 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 service or port adapter lever or other retaining mechanism does not move to the locked position, the service or port adapter is not completely seated in the midplane. Carefully pull the service or port adapter halfway out of the slot, reinsert it, and move the service or 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 service or 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. |
In this section, the illustrations that follow give step-by-step instructions on how to remove and install service adapters. This section contains the following illustrations:

Note The CSA can be installed in port adapter slot 0 or slot 1 on a VIP2 motherboard; however, the CSA will only compress and decompress data passing through interfaces on the serial port adapter in the adjacent VIP2 port adapter slot. The CSA can be installed in any available port adapter slot in a Cisco 7200 series chassis and will compress and decompress interfaces on serial port adapters installed in any other port adapter slot. The Cisco 7000 series, 7200 series, and 7500 series routers support multiple installed CSAs. |
