Overview
Broadxent 8120-R1 with firmware 6.0.25.2.0 is certified by Network Engineering to 
be use on Covad's network. This release notice is to inform about the limited 
capabilities of the firmware and the work around to make it possible to run on 
Covad's Network.
Important Notes:
1. Upgrade firmware from 5.0.0.16 to 6.0.25.2.0. 
a. Current configuration will be lost when doing the upgrade.
b. All configurations should be written down and will have to be re-created when

compatible to run on 6.0.25.2.0 release.
d. Once upgraded to 6.0.25.2.0, the CPE can no longer be downgraded to 5.0.0.16 
release.
2. When the firmware crashed, firmware recovery is done using Broadxent's Ethernet 
protocol. A PC is connected on the Ethernet port of the CPE. An application is run 
on the PC that automatically looks for the CPE and upgraded the firmware. Upgrade 
firmware using console is disabled. Console is only used for CLI.
3. When there is no Internet connection from the CPE, the web browser will 
redirect to the Broadxent Web-based DSL Configuration home page.

assigned IP and DNS information. Secondary subnet cannot use DHCP.
