2 Enter the BootROM password. After entering the correct password (no password

The Switch 8800 uses the application and configuration files it finds on the Flash 
of the Fabric from which it booted the previous time. To back up these files, you 
can copy them from Flash to compact Flash. However, there are some important 
things to know before you copy files to compact Flash:

■

If the Switch 8800 has two Fabrics installed, and you execute a 

 

command, it synchronizes the configuration file on the Flash on both Fabrics so 
that both Fabrics can use the same configuration information. 

■

The Switch 8800 does not synchronize versions of the application file between 
Fabrics. Therefore, you must manually download the application file to one 
Fabric, then copy the application file between Flashes to insure that both 
Fabrics can boot from the same file.

■

To insure that both Fabrics boot the same way, you must configure boot 
parameters with the same values on each Fabric. 

■

The system does not synchronize files between compact Flash cards or 
between compact Flash and Flash. 

■

For compact Flash to serve as a reliable file backup, you must take care that 
files are copied to compact Flash after every modification or download. 
Otherwise, you could have multiple versions of a file on your system. 

To verify the names and contents of the Flash and compact Flash on your system, 
you can use the 

 commands, as shown in the following examples:

<SW8800>dir ?

  /all           List all files 

  STRING<1-136>  [drive][path][file name]

  cf:            Device name

  flash:         Device name

  slot5#cf:      Device name

  slot5#flash:   Device name

  <cr>           

The entries 

 and 

 refer to the compact Flash and Flash on the Fabric from 

which the system last booted. If more than one Fabric is intalled on the Switch
