OL-7861-01
Removing and Installing a Line Card
Required Tools and Equipment
You need the following tools and parts to remove and install Ethernet line cards:
• Flat-blade or Phillips screwdriver
• ESD-preventive wrist or ankle strap and instructions
• Interface cables to connect the Ethernet line card with another router or switch
• Any EPAs, GBICs, SFP modules, or memory you need to install (and are not already installed)
Note If you need additional equipment, see Cisco.com or your service representative for ordering information.
Refer to the individual line card descriptions in the “Product Overviews” section on page 4 for more
information. Table 4 on page 4 summarized the hardware requirements for each Ethernet line card.
Removing and Installing a Line Card
The following sections provide procedures for removing or installing a line card:
• Guidelines for Line Card Removal and Installation, page 10
• Removing a Line Card, page 11
• Installing a Line Card, page 13
Note See the “Guidelines for Line Card Removal and Installation” section on page 10 before removing a line
card while power to the router is on.
Note The procedures in the following sections use illustrations of a Cisco 12012 Internet Router to support
the descriptions of removing and installing line cards. Although the card cages of the Cisco 12000 Series
Routers differ in the number of card slots, the designated use of slots and the process of removing and
installing a line card are basically the same. Therefore, separate procedures and illustrations for other
Cisco routers are not included in this publication.
Guidelines for Line Card Removal and Installation
Guidelines for line card removal and installation include the following:
• Online insertion and removal (OIR) is supported, enabling you to remove and install line cards while
the router is operating. OIR is seamless to users on the network, maintains all routing information,
and ensures session preservation.
Note With OIR, notifying the software or resetting the power is not required. However, you have the
option of using the shutdown command before removing a line card.
