Chapter 5 Installing Memory in the Router

Installing and Configuring Flash Memory Cards in Cisco 3620, Cisco 3640, and Cisco 3660 Routers

Step 3 Enter the boot system flash {slot0: slot1:}[partition:filename] command to specify the boot image location and name. In the following example, the boot image is located on the Flash memory card in the

0 slot, partition 3, and the filename is new.image:

Router(config)# no boot system

Router(config)# boot system flash slot0:3:new.image

Note If you omit the partition and filename variables, you are prompted for them.

Step 4 Set the configuration register to 0x2102 (the default setting), which indicates that the router should attempt to boot a Cisco IOS image from Flash memory:

Router(config)# config-register 0x2102

Step 5 Exit global configuration mode:

Router(config)# exit

Step 6 Enter the copy running-configstartup-configcommand to save the configuration changes to NVRAM.

Step 7 Enter the reload command to reload the router. When the router reloads, it will boot the image new.image from the Flash memory card in slot 0.

Erasing the Contents of a Flash Memory Card

To erase a partition or the entire contents of a Flash memory card, enter the command erase {slot0:

slot1:} [partition:]. Replace partition with the partition number. You cannot specify a filename. The following example erases the contents of partition 2 of the card in slot 1.

Note Cisco recommends first displaying the contents of the partition that you plan to erase.
