Good Habits For Managing The Zyxel Device; Leds; Figure 3 Front Panel - ZyXEL Communications P-660HW-D User Manual

• Web Configurator. This is recommended for everyday management of the ZyXEL Device
using a (supported) web browser.
• Command Line Interface. Line commands are mostly used for troubleshooting by service
engineers.
• FTP for firmware upgrades and configuration backup/restore
• SNMP. The device can be monitored by an SNMP manager. See the SNMP chapter in this
User's Guide.
• SPTGEN. SPTGEN is a text configuration file that allows you to configure the device by
uploading an SPTGEN file. This is especially convenient if you need to configure many
devices of the same type.

1.3 Good Habits for Managing the ZyXEL Device

Do the following things regularly to make the ZyXEL Device more secure and to manage the
ZyXEL Device more effectively.
• Change the password. Use a password that's not easy to guess and that consists of
different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an
earlier working configuration may be useful if the device becomes unstable or even
crashes. If you forget your password, you will have to reset the ZyXEL Device to its
factory default settings. If you backed up an earlier configuration file, you would not have
to totally re-configure the ZyXEL Device. You could simply restore your last
configuration.
