Use this command to load the new system image after the next system reload or power cycle. Step 5 Optional Repeat to specify the order in which the router should attempt to load any backup system images. Step 6 exit.
Use this command to exit global configuration mode:. Step 7 show version. Use this command to display the configuration register setting:. Step 8 If the last digit in the configuration register is 0 or 1, proceed to Step 9. Step 9 configure terminal. Step 10 config-register 0x Use this command to set the configuration register so that, after the next system reload or power cycle, the router loads a system image from the boot system commands in the startup configuration file:.
Step 11 exit. Step 12 copy run start. Use this command to copy the running configuration to the startup configuration:. Step 13 reload. Step 14 When prompted to save the system configuration, enter no :. Step 15 When prompted to confirm the reload, enter y :. Step 16 show version. Use this command to verify that the router loaded the proper system image:. To load the new system image from ROM monitor mode, follow these steps. Step 1 dir flash0: [ partition-number : ].
Note whether the new system image is the first file or the only file listed in the dir flash0: command output. Step 2 confreg 0x Step 3 boot flash0: [ partition-number : ] filename. Use this command to force the router to load the new system image:. Step 5 enable. Use this command to enable privileged EXEC mode, and enter your password if prompted:. Step 6 configure terminal. Step 7 no boot system. Eliminate all entries in the bootable image list, which specifies the system image that the router loads at startup:.
Step 8 If the new system image is the first file or only the file displayed in the dir flash0: command output, this step is not required. Use this command to load the new system image after the next system reload or power cycle:.
Step 9 Optional Repeat to specify the order in which the router should attempt to load any backup system images. Step 10 exit.
Step 11 copy run start. To aid file recovery and to minimize downtime in the event of file corruption, we recommend that you save backup copies of the startup configuration file and the Cisco IOS software system image file on a server. Tip Do not erase any existing backup copies of your configuration and system image that you saved before upgrading your system image.
If you encounter serious problems using your new system image or startup configuration, you can quickly revert to the previous working configuration and system image. This section describes how to upgrade the Cisco IOS image on the access point. To upgrade the IOS image on the access point, establish connectivity between the access point and the download server by following these steps:.
Enters the configuration mode for a Gigabit Ethernet interface on the router. Router config-if ip address Sets the IP address and subnet mask for the specified Gigabit Ethernet interface. Enables the Gigabit Ethernet interface, changing its state from administratively down to administratively up. Exits configuration mode for the Gigabit Ethernet interface and returns to global configuration mode.
The access point communicates with the external server and setup option 43 for the controller IP address in the DHCP pool configuration.
The following example shows a dhcp pool configuration:. Perform the following steps to confirm connectivity. Ping the external server from the router to confirm connectivity. Enter the service-module wlan-ap 0 session command to establish a session into the access point.
Ping the external server from the access point to confirm connectivity. The following example shows a sample router and access point configuration:. Follow the image upgrade instructions at Cisco. Note If the access point enters Bootloader mode, manually configure the IP address, default router, netmask, and default gateway to upgrade the IOS image.
Here is an example configuration. JDA flash0: apk9w7-tar. The following sections provide references related to upgrading the system image on your router. Matching Cisco IOS releases and features to hardware.

Router copy flash0: tftp: Source filename [running-config]? Address or name of remote host []? Ensuring Adequate Flash Memory for the New System Image This section describes how to check whether your router has enough flash memory to upgrade to the new system image and, if necessary, how to properly delete files in flash memory to make room for the new system image.
Copying the System Image into Flash Memory This section describes how to copy the system image into the compact flash memory card for your router. Prerequisites The following details the logistics of upgrading the system image. Establish a console session to the router.
We recommend that you connect your PC directly to the router console port. Typically, the same filename is entered as was used in Step 4 : Destination filename []? Erase flash0: before copying? Caution Using the tftpdnld ROM monitor command may erase the system image, configuration, and data files.
System image, configuration, and data files must be present on USB CF in slot0 for the router to boot and perform normal file operations. Enter ROM monitor mode 2. Locate the compact flash memory card slot on the router chassis. For help with locating the slot and instructions for removing and inserting the card, see the hardware installation guide for your router. Caution Removing the compact flash memory card may disrupt the network because some software features use the compact flash memory card to store tables and other important data.
