Instruction

Perform these steps:

  1. Once you boot the CE-590, log in with the admin/default user name and password.

  2. Issue the show disks current command to be sure of the completion of the partition.

    If incomplete, partition the disk with the issue of this command:

    ContentEngine# disk config sysfs 5%
    
    
    !--- This can be any number, which depends on how you choose 
    !--- to do the configuration.
    
    
  3. Reload the CE-590.

  4. Log in, go to config mode, and configure any one interface.

    For example, configure e0, as this example shows:

    ContentEngine(config)# interface Ethernet0
    ContentEngine(config-if)# ip address x.x.x.x m.m.m.m
    
    ContentEngine(config-if)# exit
    ContentEngine(config)# ip route 0.0.0.0 0.0.0.0 g.g.g.g
    
    
  5. Copy the downgrade image from the FTP server.

    This is an example:

    ContentEngine# copy ftp install  
    ce590-ACNS-4.2.3-TO-CE-Cache-231.bin
  6. Reload the CE-590.

  7. Follow Step 4, and configure the interface IP and gateway IP address.

  8. Issue the show disks command for each disk in the list.

    The command syntax is:

    ContentEngine# show disks
    
  9. Transfer the upgrade image ce590-cache-251.pax via TFTP from the TFTP server.

    Issue these commands:

    ContentEngine# cd /local
    ContentEngine# copy tftp disk
    

    Follow the screen prompts.

  10. Reload the CE-590.

  11. Issue the show version command to be sure that you have the correct image.
