After changing the network parameters, the device attempts to load the device's firmware
file (cmp) and various configuration files from the TFTP server’s IP address received from
the BootP/DHCP server. If a TFTP server’s IP address isn’t received, the device attempts
to load the cmp file and / or configuration files from a preconfigured TFTP server. Thus, the
device can obtain its network parameters from BootP or DHCP servers, and its software
and configuration files from a different TFTP server (preconfigured in the ini configuration
file).
If BootP/DHCP servers are not found or when the device is reset using the Web interface
or SNMP, it retains its network parameters and attempts to load the cmp file and / or
configuration files from a preconfigured TFTP server. If a preconfigured TFTP server
doesn’t exist, the device operates using the existing software and configuration files on its
flash memory.

one second (configured by the BootPDelay ini file parameter). By default, the
