Preparing for the upgrade
Before you upgrade system software, complete the following tasks:
Set up the upgrade environment as shown in Table 20.
Configure routes to make sure that the router and the file server can reach each other.
Run a TFTP or FTP server on the file server.
Log in to the CLI of the router through the console port.
Copy the upgrade file to the file server and correctly set the working directory on the TFTP or FTP server.
Make sure the upgrade has minimal impact on the network services. During the upgrade, the router
cannot provide any services.
e BootWare menu, if you choose to download files over Ethernet, the Ethernet port must be
GE0 on an MSR2003, MSR2004
-24, MSR2004-48, MSR3012, MSR3024, MSR3044, and
MSR3064 router, and must be M-GE0 on an MSR4060 and MSR4080 router.
