Chapter 10 Update
The following screen capture shows the Update tab.
The Update tab on the Web interface provides one method to update the ZyWAN firmware to a later version.
See the following section, Updating Using WinSCP on page 106 , for a more recommended method of
updating, especially for systems where the default network is a cellular or private network.
Warning:
The update process may take a significant amount of time, possibly several minutes,
depending on the size and number of updates that have to occur. Do not remove
power or perform a Linux command line ‘
reboot
’ until the updates have completed.
In some cases, the ZyWAN will be required to reboot automatically in the middle of its
update process. If this occurs, it will continue installing additional files after the reboot.
When this occurs, the following line will be seen on a serial console after the
intermediate reboot:
**** more updates available ****
Updating Via the Web Interface
In the Update URL field, enter the network address URL (Uniform Resource Locator) from which an update
file may be downloaded. The address must be accessible through the default network interface of the
ZyWAN and must point to a file server location containing update files for the ZyWAN. Some examples of
addresses which could be used are:
http://files.arcom.com/Zywan/updates (HTTP download over the Internet)
http:// ip_address/pathname (HTTP download from ip_address which must be
an HTTP server, with the files existing in pathname )
--ftp-user=
username
--ftp-password=
password
ftp://
ip_address
/
somepath
(for FTP download from ip_address/somepath ,
using username and password )
The server location must contain the latest versions of the files, such as:
version_multi.txt
version_multi2.txt
Zywan-update-1_
x
.star
(where files for versions 1.5 and higher would be
or
Zywan-update_v1. xx .star
required to update a version 1.4 ZyWAN)
If no Update URL is entered, the ZyWAN will use the default address of
http://files.arcom.com/Zywan/updates . When the Update Zywan button is pressed, the files are downloaded
and installed. After the update is complete, the ZyWAN must be rebooted.
