FIRMWARE UPDATE
The NetMan plus firmware can be updated via serial line or via network (Netboot).
WARNING: updating the firmware resets the current password (default 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 SNMP, via Telnet or via UDP as described below.
The service relating to the command used must be active;
SNMP: send a SET 3.6.1.4.1.5491.6.8.1 command with value 2;
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.
