Upgrading to a New Firmware Release

Perform the following steps to upgrade to a new firmware release:

1. Download the new firmware from Cisco.com Software Center at http://www.cisco.com/cisco/software/navigator.html.

Choose Products -> Routers -> Branch Routers -> Cisco 800 Series Routers -> Cisco 886, 887, 896 or 897 VA Integrated Services Router -> Very High Bitrate DSL (VDSL) Firmware > VA_A_38q_B_38r1_24j.bin

2. Copy the VA_A_38q_B_38r1_24j.bin firmware to a designated location; for example, router flash or a TFTP server.

3. Configure the router to load the new firmware from a designated location.

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
