Introduction

This section describes how to perform tasks performed either by root or the system administrator.

These tasks fall under the general heading of system administration and include firmware upgrades,

saving configurations, resetting the unit to defaults, and disaster recovery procedures.

Upgrade the firmware

Web interface

The web interface allows you to download the latest firmware version to the Digi CM unit. The latest

firmware can be found at:

https://www.digi.com/products/consoleservers/digicm#productsupport

Do the following to upgrade the firmware:

Access the web interface.

Under the

System administration

heading, choose

Firmware upgrade

Select Local machine or CF card (if configured).

Choose the Browse button and locate the firmware download.

Choose

Upgrade

. The Digi CM unit will automatically reboot when the upgrade is complete.

Note

Do not power cycle the unit for five minutes after the firmware upgrade is completed, as the

unit is writing the firmware to flash!

Configuration management

Configuration management allows you to save all or parts of your configuration. You can also

establish the time frame to save the configuration either periodically or 10 minutes after the latest

changes. The Digi CM unit saves all configurations when the

Save & apply

button is used or the

Apply changes

link is used. These configurations are saved to the loca lDigi CM unit in /tmp/cnf

directory by default. Manage these configurations by exporting the files to your location of choice.

Click

System administration

Configuration management

. The Configuration management

screen appears.
