Firmware Upgrade Download new firmware (when available) from the ZyXEL web site and
use the web configurator, CLI or an FTP/TFTP tool to put it on the
Switch.
Note: Only upload firmware for your specific model!
Configuration Backup &
Restoration Make a copy of the Switch’s configuration and put it back on the Switch
later if you decide you want to revert back to an earl
i er configuration.
Access Control You can specify the service(s) and computer IP address(es) to control
access to the Switch for management.
Cluster Management Cluster management (also known as iStacking) allows you to manage
switches through one switch, called the cluster manager. The switches
must be directly connected and be in the same VLAN group so as to be
able to communicate with one another.
