Handling Line Cards

Caution Always handle the line card by the carrier edges and handle; never touch the line card components or

connector pins. (See Figure 3-1.)

Figure 3-1 Handling a Line Card

Online Insertion and Removal

The Cisco 7304 router supports online insertion and removal (OIR) of line cards; therefore, you do not

have to power down the router when removing and replacing a 6T3 line card on a Cisco 7304 router. The

Cisco 7304 router also supports CLI-controlled OIR (see the “CLI-Controlled OIR” section on

page 4-17), which allows for the completion of data traffic before the active interfaces are shut down.

Note CLI-controlled OIR is the recommended way of performing OIR on this platform.

Note As you disengage the line card from the router, online insertion and removal (OIR) administratively

shuts down all active interfaces on the line card.

Note Before you begin installation, read Chapter 2, “Preparing for Installation,” for a list of parts and tools

required for installation.
