Recovering from Corrupted Software 89 Recovering from Corrupted Software If the Alert LED remains permanently on following power-up, it is possible that the system software has become corrupted. In this condition, the Gateway will enter a "recovery" state; DHCP is disabled, and the LAN IP address is set to 192.168.1.1. Follow the instructions below to upload a new copy of the system software to a Gateway unit in this state. Ensure that one of your computers has a copy of the new software image file stored on its hard disk or available on CD-ROM. The latest software is available on 3Com's Web site at: www.3com.com. 1 Remove power from the Gateway and disconnect the Cable/DSL modem and all your computers, except for the one computer with the software image. 2 You will need to reconfigure this computer with the following static IP address information: ■ IP address: 192.168.1.2 ■ Subnet mask: 255.255.255.0 ■ Default Gateway address: 192.168.1.1 3 Restart the computer, and re-apply power to the Gateway. 4 Using the Web browser on the computer, enter the following URL in the location bar: http://192.168.1.1. This will connect you to the Microcode Recovery utility in the Gateway. 5 Follow the on-screen instructions. Enter the path and filename of the software image file. 6 When the upload has completed, the Gateway will restart, run the self-test and, if successful, resume normal operation. The Alert LED will go out. 7 Refer to the Installation Guide to reconnect your Gateway to the Cable/DSL modem and the computers in your network. Do not forget to reconfigure the computer you used for the software upload. If the Gateway does not resume normal operation following the upload, it may be faulty. Contact your supplier for advice.
