Note: In a cell environment, the DPOD server mentioned below is the Cell Manager.

In order to use the appliance firmware upgrade feature, some special configuration needs to be done:

1. Change the "Firmware Upgrade - Repository Path" in the system parameters page to a new dedicated mount point on DPOD server.

2. Change the "Firmware Upgrade - Local Node IP Address" in the system parameters page to the IP address of the DPOD server that monitored gateways should use to access it via SSH.
   Make sure the gateways can access the DPOD server using this IP address and port 22, and that no firewall or routing issues prevent that.

3. During a firmware upgrade, the DataPower gateway will use SSH to pull the firmware image from DPOD. Use the following steps to configure a new OS user that will be used for that.

   1. The system administrator should create a non-privileged user in the DPOD server (e.g: dpodssh) and set its password:

      sudo useradd -md /home/dpodssh -s /bin/bash dpodssh sudo passwd dpodssh

   2. Verify that user and password configured above are valid, and that the password is not expired, by manually logging in to the DPOD server using SSH with the configured user name and password.

   3. Verify that the user has access to the repository path configured at item 1. The access to the directory should include x (execute), so the user is able to list the files in the directory.
      While connected with the user, try to list (ls) the repository path and make sure the user can access it.

   4. Change the "Firmware Upgrade - OS User Name" and "Firmware Upgrade - OS User Password" in the system parameters page to the DPOD server user and password configured above.
