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. How do I access the Prestige SMT menu?
The SMT interface is a menu driven interface, which can be accessed via a RS232
console or a Telnet connection. To access the Prestige via SMT console port, a
computer equipped with communication software such as HyperTerminal must be
configured with the following parameters.
• VT100 terminal emulation
• 9600bps baud rate
• N81 data format (No Parity, 8 data bits, 1 stop bit)
The default console port baud rate is 9600bps, you can change it to 115200bps in
Menu 24.2.2 to speed up the SMT access.
3. What is the default console port baud rate? Moreover, how do I change it?
The default console port baud rate is 9600bps. When configuring the SMT, please
make sure the terminal baud rate is also 9600bps. You can change the console baud
rate from 9600bps to 115200bps in SMT menu 24.2.2.
4. How do I update the firmware and configuration file
?
You can upload the firmware and configuration file to Prestige using console port,
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.
5. How do I upload the ZyNOS firmware code via console?
The procedure for uploading ZyNOS via console is as follows.
a. Enter debug mode when powering on the Prestige using a terminal emulator
b. Enter 'ATUR' to start the uploading
