Select FTP update… and press <SEL>. Press <

The unit will reboot once the update is complete. It may also give a message about
"invalid non volatile RAM values". This message is normal.
8. Press <SYSTEM> once and verify that the new software version is shown. If not,
repeat the update. The update process is now complete.
NOTE: It is not abnormal for the system to display a message "Some corrupt non volatile
values were detected". You can disregard this message.
Updating a 10 Base-T Xstream directly from the Telos ftp site
Note: This method is preferred if your firewall allows access to the Telos ftp site
(ftp.zephyr.com). In this case, you need only a connection to the internet ‐ a local computer is
not needed.
If your firewall allows FTP (usually port 21) through, then the Xstream can download the new
software directly from the Telos FTP site (
ftp.telos‐systems.com) . If your firewall does not allow
direct FTP download, see sections I and II, above.
Software update step-by-step (Telos Remote Server)
It is important that the download process completed without interruption. If local power is not
reliable, you might wish to place the Zephyr Xstream on an uninterruptible power supply.
1. Connect the Zephyr Xstream to a network with internet access.
2. Program the following information into your Zephyr Xstream. Ask your network
administrator if you need help.
Press the <SYSTEM> button three times and enter the following information in this
menu:
IP Address –
(The IP address for this unit). As with any computer on an IP network, the
Xstream must have an IP address before it can be used over the network.
SN Mask –
The subnet mask is to determine the size of your local network. All packets
addressed to a destination outside this local area are sent to the gateway
node entered in the next selection. Normally you should enter
255.255.255.0 here.
Gateway –
This is the IP address of a gateway router connecting you to the internet.
