Formatting a Flash PC Card

Chapter 3 Configuring the Catalyst 4840G Processor

Using Flash PC Cards

A Flash PC card is blank and must be formatted before use. The formatting procedure erases all information on the Flash PC card.

To format a Flash PC card, follow these steps:

Step 1 Back up files that you have on an existing Flash PC card by copying them to a TFTP server using the copy flash tftp: command.

Step 2 Insert the Flash PC card you want to format into slot 0. Step 3 Format the Flash PC card using the format command.

This example shows how to format a Flash PC card in slot 0 and name it “NewPCcard”:

SLB-Switch#format slot0:

Format operation may take a while. Continue? [confirm] y

Enter volume ID (up to 30 characters): NewPCcard

Formatting sector 1

Format device slot0 completed

This example uses a 16-MB Flash PC card. At the line Formatting sector 1, the system counts the card’s sectors backward from 128 to 1 as it formats them. For 20-MB Flash PC cards, the system counts backward from 160 to 1.

Note For more information on inserting a Flash PC card, refer to the Catalyst 4840G Chassis Installation Guide.

Copying the Startup Configuration File to the Flash PC Card

Command	Purpose

This example shows how to copy the startup configuration file to the Flash PC card in slot 0; the default filename is used:

SLB-Switch#copy nvram:startup-config slot0:

Destination filename [startup-config]? y 3790 bytes copied in 0.484 secs SLB-Switch#
