ZyNOS FAQ

1. What is ZyNOS?

ZyNOS is ZyXEL's proprietary Network Operating System. It is the platform on
all Prestige routers that delivers network services and applications. It is
designed in a modular fashion so it is easy for developers to add new features.
New ZyNOS software upgrades can be easily downloaded from our FTP sites
as they become available.

2. What's Multilingual Embedded Web Configurator?

Multilinggual Embedded Web Configurator means that it can display with 3
kinds of languanges: English, French, and German. By factory default it
displays with English, and you can change it in Web GUI.

3. How do I access the P-662H-D Command Line Interface (CLI)?

The Command Line Interface is for the Administrator use only, and it could be
accessed via telnet session or consol connection.
Note: It is protected by super password, '1234' by factory default.

4. How do I update the firmware and configuration file?

You can do this if you access the P-662H-D as Administrator. You can upload
the firmware and configuration file to Prestige from Web Condigurator, or using
FTP or TFTP client software. You CAN NOT upload the firmware and
configuration file via Telnet because the Telnet connection will be dropped
during uploading the firmware. Please do not power off the router right after the
FTP or TFTP uploading is finished, the router will upload the firmware to its
flash at this moment.
Note: There may be firmware that could not be upgraded from Web
Configurator. In this case, ZyXEL will prepare special Upload Software
for you. Please read the firmware release note carefully when you want to
upload a new fireware.
