Cisco Cisco IOS Software Release 12.2(10) 發佈版本通知

When you upgrade from Cisco IOS Release 12.1(5)DA2 or earlier images on the NI-2 card to 
Release 12.2(10)DA5, you must reformat the bootflash on the NI-2 card.

If you are upgrading from Cisco IOS Release 12.1(6)DA, 12.1(6)DA2, 12.1(7)DA, 12.1(7)DA2, 
12.1(7)DA3, 12.2(1b)DA, 12.2(1b)DA1, 12.2(5)DA, 12.2(5)DA1, 12.2(7)DA, 12.2(10)DA, 
12.2(10)DA1, 12.2(10)DA2, 12.2(10)DA3 or 12.2(10)DA4, you do not need to reformat 
the bootflash. You can skip this section and follow the DSLAM upgrade procedure at the following 
URL:

.

We highly recommend that you have console access to the NI-2 card during the upgrade procedure. 
You can use the console connection to troubleshoot any unexpected events that occur during 
the upgrade.
