Chapter 3 Configuring the Catalyst 4840G Processor
Using Flash PC Cards
Copying a System Image from a TFTP Server to a Flash PC Card
You should have a copy of the current system image on a Flash PC card in case the file in Flash memory
becomes corrupted. You can replace the system software by copying the backup image from the Flash
PC card to the onboard Flash memory.
Note Be sure that you have a properly formatted Flash PC card in the appropriate slot before
beginning this procedure.
To copy the system image from the TFTP server to a Flash PC card, perform this task:
This example shows how to copy a system image file from the default TFTP server to the current Flash
PC card:
SLB-Switch# copy tftp flash:
Source filename []? cat4840G-in-mz.X.bin
Address or name of remote host [172.8.1.129]? y
Destination filename [cat4840g-in-mz.X.bin]? y
5746016 bytes available on device slot0, proceed? [confirm] y
Now that you have configured the processor, see Chapter 4, “Configuring Interfaces,” for instructions
on interface configurations for your SLB switch.
Command Purpose

card.
