zreset the Device Server to the factory defaults

password
DHCP/BOOTP
You can use DHCP/BOOTP to perform the following actions on a single or multiple Device Servers
on bootup:
zauto-configure with minimal information; for example, only an IP address
zauto-configure with basic setup information (IP address, subnet/prefix bits, etc.)
zdownload a new version of firmware
zdownload a full configuration file
DHCP/BOOTP is particularly useful for multiple installations: you can do all the Device Server’s
configuration in one DHCP/BOOTP file, rather than configure each Device Server manually.
Another advantage of DHCP/BOOTP is that you can connect a Device Server to the network, turn on
its power and let autoconfiguration take place. All the configuration is carried out for you during the
DHCP/BOOTP process.

DHCP/BOOTP Parameters

The following parameters can be set in the DHCP/BOOTP bootp file:
zSW_FILE—The full path, pre-fixed by hostname/IP address (IPv4 or IPv6), and file name of the
firmware update.
zCONFIG_FILE—The full path, pre-fixed by hostname/IP address (IPv4 or IPv6), and file name
of the configuration file. Note: these parameters include clear text user passwords.
zGUI_ACCESS—Access to the Device Server from the HTTP WebManager. Values are on or
off.
zSECURITY—Restricts Device Server access to devices listed in the Device Server’s host table.
Values are yes or no.
zTFTP_RETRY—The number of TFTP attempts before aborting. This is a numeric value, for
