Updating POST Code

This procedure shows you how to upgrade POST code from a file or TFTP.

Typically, POST upgrades are not required and should only be done if the

firmware release notes indicate that this step is required.

Note: The preferred method is to use your web browser and download the file onto

your PC. TFTP, however, is often used in UNIX environments, so TFTP is

supported as well.

Prerequisite

This procedure assumes that:

• You have already downloaded the firmware file from the Digi web site

• TFTP is running (if you are using the TFTP option)

Procedure

Open a web browser and enter the device server’s IP address in the

URL window.

2. When the device server prompts you to log in, enter the following:

• User Name is root

• The root default password is dbps

3. Choose Upgrade Firmware from the main menu.
