• Web Configurator. Use this for everyday management of the ZyXEL Device using
a (supported) web browser.
• SNMP. The device can be monitored by an SNMP manager. See the SNMP
chapter in this User’s Guide.
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.
1.4 Hardware Connections
See the Quick Start Guide for the ZyXEL Device’s main hardware connections.
1.4.1 Connecting POTS Splitters
Use POTS (Plain Old Telephone Service) splitters to separate the telephone and
ADSL signals. This allows simultaneous Internet access and telephone service on
the same line. A splitter also eliminates the destructive interference conditions
caused by telephone sets.
Install the POTS splitters at the point where the telephone lines enter your
premises.
1 Connect the side labeled “Phone” to your telephone.
2 Connect the side labeled “Modem” or “DSL” to your ZyXEL Device.
3 Connect the side labeled “Line” to the telephone wall jack.
