Installing the Router 3-31
Using the Flash Memory Card
Formatting the Flash Memory Card
The Flash memory card shipped with a spare RP or shipped with a system is already formatted.
However, a spare Flash memory card is shipped blank and must be reformatted before use. Also, if
you plan to use a Flash memory card that was formatted on an RSP-based system (Cisco 7500
series), you must first reformat the card on your system.
Note The following procedure assumes you have already booted your router.
Caution The formatting procedure erases all information on the Flash memory card. To prevent the
loss of important data that might be stored on a Flash memory card, proceed carefully. If you want
to save the data on a Flash memory card, copy the data to a server before you format the card.
Use the following procedure to format a new Flash memory card:
Step 1 Using the procedures in the section “Installing and Removing the Flash Memory Card,”
insert the Flash memory card into the PCMCIA slot.
Step 2 To format the Flash memory card, use the format slot0 command as follows. (Use only
Intel Series 2+ Flash memory cards.)
Router# format slot0:
All sectors will be erased, proceed? [confirm]
Enter volume id (up to 30 characters): MyNewCard
Formatting sector 1
Format device slot0 completed
Router#
Note For this example, an 8-MB Flash memory card was used, and at the line “Formatting sector,”
the system counted the card’s sectors backwards from 64 to 1 as it formatted them. For 16-MB Flash
memory cards, the system counts backwards from 128 to 1.
The new Flash memory card is now formatted and ready to use.
Note For complete command descriptions and configuration information, refer to the Router
Products Command Reference publication and the Router Products Configuration Guide.
Copying an Image into the Flash Memory Card
With the Flash memory card formatted, you can now copy an image into it. To copy an image, use
the following procedure, which assumes the following:
• The system is running Cisco IOS Release 11.0 or later.
• The bootable image you wish to copy to the Flash memory card exists on a TFTP server to which
you have access (meaning you know its name and have connectivity to it), and at least one
interface is available over which you can access this server.
