"This message is sent by the system ("RAS" displays as
the system name if you haven’t configured one) when the
router generates a syslog. The facility is defined in the web
MAIN MENU->LOGS->Log Settings page. The severity is
the log’s syslog class. The definition of messages and
notes are defined in the various log charts throughout this
appendix. The “devID” is the last three characters of the
MAC address of the router’s LAN port. The “cat” is the
same as the category in the router’s logs.

Overview
This chapter explains how to upload new firmware, manage configuration files and restart
your ZyXEL Device.
Use the instructions in this chapter to change the device’s configuration file or upgrade its
firmware. After you configure your device, you can backup the configuration file to a
computer. That way if you later misconfigure the device, you can upload the backed up
configuration file to return to your previous settings. You can alternately upload the factory
default configuration file if you want to return the device to the original default settings. The
firmware determines the device’s available features and functionality. You can download new
firmware releases from your nearest ZyXEL FTP site (or www.zyxel.com) to use to upgrade
your device’s performance.
1
Only use firmware for your device’s specific model. Refer to the label on the
bottom of your ZyXEL Device.
21.1.1
What You Can Do in the Tool Screens
•
Use the
Firmware Upgrade
screen (
Section 21.2 on page 293
) to upload firmware to
your device.
•
Use the
Configuration
screen (
Section 21.3 on page 295
) to backup and restore device
configurations. You can also reset your device settings back to the factory default.
•
Use the
Restart
screen (
Section 21.4 on page 297
) to restart your ZyXEL device.
21.1.2
What You Need To Know About Tools
Filename Conventions
The configuration file (often called the romfile or rom-0) contains the factory default settings
in the menus such as password, DHCP Setup, TCP/IP Setup, etc. It arrives from ZyXEL with a
“rom” filename extension. Once you have customized the ZyXEL Device's settings, they can
be saved back to your computer under a filename of your choosing.
