IRMWARE UPDATE
The
NetMan plus
firmware can be updated via serial line or via network (Netboot).
WARNING:
updating the firmware resets the current password (de
fault configuration: “password”),
loses the clock‟s settings and deletes the event.log and data.log files.
Update via serial line
Connect the “Serial” port of
NetMan plus
to the serial port of the PC by means of the null-
modem cable provided;
Execute the NetManplus.exe program;
Select the folder containing the update files;
When prompted, press the
NetMan plus
RESET button and click on the “OK” key. Wait for
the end of the operation.
Firmware update via serial line
Update via network (Netboot)
Configure and start the DHCP/BOOTP server. The DHCP/BOOTP configuration must
include the TFTP server address at the item “next server IP” or “option 150”. On Windows
Server for example, it is “TFTP server name” on “code 66”.
Start the TFTP server; the update file must be present on this server. The TFTP server
must have the address configured in the previous step.
Start the update in one of the following ways:
1. by closing the jumper JP14.
NetMan plus
automatically starts Netboot at each device
start-up;
2. by sending a network command via Telnet or via UDP as described below. The service
relating to the command used must be active;
Telnet: connect with user “root” and own password, enter the
Save and load
menu
and select “Netboot”;
UDP: execute the “upgrade <ip address> -n” command (where <ip address> is the
address of
NetMan plus
). A group of addresses can be set for the simultaneous
update of several
NetMan plus
; for example, by setting an IP address
10.1.255.255, the command is sent to all the devices within the address range
10.1.*.*.
3.
by connecting to the configuration serial port and choosing the “Netboot” option.
