in order to make the new file the default program to run after a reset.
8. Depress the “ F4 ” key to log-off the session with the current gateway. “Econ” displays the list of
all devices from the initial discovery phase. Select another gateway in the network and repeat
steps 4 through 7.
9. Once all the gateways in the network have the new program, log onto each one (using econsole)
and issue the command:
>reboot
to cause the gateway to restart using the new firmware.
10. Wait at least ten seconds from the moment you entered the reboot command, then press <CR>.
Econsole automatically attempts to reconnect to the same gateway. Once a new session with that
gateway is reopened issue the command:
> version
and check that the gateway is indeed executing the new version.
11. Repeat the previous two steps for each gateway in the network.
Note that the file downloads are executed with serial links in full operation. The only downtime in
the link occurs when the gateways are rebooting. Unless the major version of the firmware has
changed the gateway configuration is kept intact when a new version is started (see the release notes
for details). The downtime for the gateway being restarted, is typically less than twenty seconds.
3.2.3 Installing new firmware using Telnet
Telnet is a protocol that allows you to conduct a remote gateway command session from a local host.
The gateway must have been pre-configured with an IP address and be reachable, over the network,
from the local host. Refer to section 5 for details on how to configure a gateway IP address and
initiate a Telnet session. The Telnet terminal emulation must have the capability of sending an
ASCII file to the remote machine. The following description assumes you are using Hyperterminal as
the local Telnet terminal emulation.
1. Verify that the new software is available in the local machine. The download software for
upgrade via Telnet must have a “.dwn” extension, e.g., nxg01_05.dwn.
2. Initiate a Telnet session with the gateway as described in section 5.
3. If the gateway configuration has been password protected, you must first unlock the protection
with the command:
> unlock enable-configuration= password
(when the configuration is unlocked, the gateway prompt ends with the characters ‘#>. In locked
mode the prompt does not include the ‘#’ character).
4. Issue the command:
