If an FTP server does not use standard FTP port numbers, you cannot use it to download FTP servers for Nortel software. For more information, contact Nortel Customer support.

Note: You cannot upgrade the software through a branch office tunnel that is translating the management address with dynamic Network Address Translation (NAT).

If file retrieval fails, the VPN Router retries the transfer. The WU-FTP server does not support this behavior and can cause the negotiation to fail. Explore connectivity issues as the first possible level of failure.

Checking available disk space

Nortel recommends that you keep a maximum of four software versions on the system disk. If four versions already exist on the Admin > Upgrade window, you must delete one version before you download another version.

To remove a software version:

1Select Admin > File System.

2Select the Hard Drive (/ide0/).

3Click Display.

A list of the versions on the VPN Router appears.

4Click the version you want to view and click Details. When the window refreshes, you see the directory that you just selected. Click Delete Directory.

A new window appears verifying this is what you intended to do. If there is more then one image on the hard drive, follow the above process to delete all the older image upgrades.
