How to upgrade the system Flash in Cisco 2600 series routers
By Brad Reese on Tue, 04/29/08 - 8:13am.
The Cisco 2600 series routers have a single Flash SIMM that contains the Cisco IOS Software.
The Flash upgrade SIMMs are delivered blank, without any Cisco IOS Software.
After the upgrade, the router is in ROM Monitor (ROMmon) mode, and requires software recovery.
To resolve, you may wish to perform these steps:
| 1. | Copy the existing Cisco IOS Software to a TFTP server. |
For instructions refer to:
