Router in Boot Mode: Router (boot)>
If the router is in boot mode, it means the router has a corrupt or missing Cisco IOS image. Use this procedure to upgrade the
Cisco IOS software.
Set the configuration register value to 0x0 for the next reload.
Step 1
Do not save anything while you are in boot mode. Do not use the saving commands (write mem or copy run start) and
Note
answer no to any prompt suggesting that you save your current configuration. If you save while you are in this mode,
your configuration can be partially or completely erased.
Router(boot)>
Router(boot)>enable
Password: password
Router(boot)# conf t
Enter configuration commands, one per line.
Router(boot)(config)# con
Router(boot)(config)# config-register 0x0
Router(boot)(config)# ^Z
Verify the TFTP server has IP connectivity to the router by confirming that the router IP address and default gateway
Step 2
(if necessary) are set. Ping the router to verify that a network connection exists between it and the TFTP server.
Step 3 Copy the new software image from the TFTP server to the router. (Keep a copy of the router configuration before
upgrading the router software.)
Router> enable
Password: password

Router# copy tftp disk0:
Step 4 Specify the IP address of the TFTP server.
Address or name of remote host [255.255.255.255]? 172.17.247.195
Step 5 Specify the filename of the new Cisco IOS software image.
Source file name? c7300-js-mz.121-9.E
The image name varies depending on the filename of the image on the TFTP server.
Note
Step 6 Specify the destination image filename. This is the name the new software image will have when it is loaded onto the
router. The image can be named anything, but common practice is to enter the UNIX image filename.
Destination file name c7300-js-mz.121-9.EP
The copying process takes several minutes; the time differs from network to network. During the copy process,
messages are displayed to indicate which files have been accessed.
The exclamation point (!) indicates that the copy process is taking place. Each exclamation point (!) indicates that ten
packets were transferred successfully. A checksum verification of the image occurs after the image is written to Flash
memory. The router reloads itself with the new image when the software upgrade is complete.
Step 7 Reload the router.
Router(boot)# reload
*Mar 1 00:30:49.972: %SYS-5-CONFIG_I: Configured from console by console
System configuration has been modified. Save? [yes/no]: NO
Proceed with reload? [confirm] YES
Because the configuration register is set to 0x0, the router will go into ROMmon when you reload and you will load
the image you just copied. Follow the instructions in the
End with CNTL/Z.
"ROMmon prompt: rommon # >" section on page 34.
