Chapter 3 Configuring the Catalyst 4840G Processor
Using Flash PC Cards
Formatting a Flash PC Card
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
To copy the startup configuration file from NVRAM to a Flash PC card after the Flash PC card is
formatted and ready to use, perform this task:
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#
Command Purpose
