on the Apply button. Clicking on Logout and Save saves the
new setting in the USB-Server and the device can again be
accessed under the new IP address.
3.2.3 System Name
To support a possible later automated updating of the DNS
system using the DHCP server, the USB-Server identifies itself
within the DHCP protocol by its system name. The factory
default name is USBSERVER- followed by the last three places of
the Ethernet address. For example the factory set system name
of a USB-Server having Ethernet address 00:c0:3d:01:02:03 is
USBSERVER-010203. The system name of the USB-Server can be
changed using Web Based Management.
3.2.4 Lease time
The lease time determined and sent by the DHCP server
specifies the time limit of the assigned IP address. After half
the lease time has expired the USB-Server attempts to extend
the time and update the address. If this is not possible by the
time the lease time expires, for example because the DHCP
server can no longer be reached, the USB-Server deletes the IP
address and reverts to the factory default address
190.107.233.110. At the same time the cyclical search for
alternate DHCP servers for assigning a new IP address is started.
Because the clock is absent the lease time for the current IP
address is no longer available after a reset. After the restart
there is then a corresponding update request with the original
DHCP server. If the latter cannot be reached at this point in
time, the USB-Server deletes the IP address and reverts to the
factory default address 190.107.233.110. At the same time the
cyclical search for alternate DHCP servers for assigning a new
IP address is started.
