Firmware Upgrades 

If you need to re-install your current firmware, it is located in the firmware directory of the CD 
you received with your Blue Heat/Net Sync. 
 
Newer firmware versions are available from Connect Tech‟s website, 

http://www.connecttech.com/asp/Support/DownloadZone.asp

. Choose Blue Heat/Net Sync 

product. Ensure the following parameters are set: 

mip, sip, gip

 and 

dns_ip

 using the SCM. To 

upgrade your Blue Heat/Net Sync firmware, you can use any of the following three methods, 
depending on your preference. 

Upgrade using WCM (Web Configuration Manager)

 

 

The Web Configuration Manager is the easiest way to upgrade your firmware.  Simply log onto 
the WCM as described in the

 WCM (Web Configuration Manager)

 section, and click on the 

Firmware link on the left menu. This will bring you to the Firmware page.  You will have the 
option to upgrade from the remote CTI website, or to download the upgrade from a local FTP 
server. 
If you choose to upgrade via a local FTP server, copy the firmware (*.tar) file to the anonymous 
directory of a local FTP server. If you do not have a local FTP server, contact your system 
administrator to set one up.  
 

Upgrade using SCM (Serial Configuration Manager) 
 

The SCM method of upgrading is used when the Blue Heat/Net Sync does not boot properly. 
You can reinstall your original firmware from the supplied CD, or you can download any newer 
versions that exist from the CTI website in the 

http://www.connecttech.com/asp/Support/DownloadZone.asp 

or go directly to the FTP site as 

indicated below. 
 
You will need the use of a TFTP server.  (Contact your system administrator to obtain access to 
a TFTP server).  Download the most recent firmware components from the FTP site 

ftp://ftp.connecttech.com/pub/BHN/ . 

These files include 

BHNuClinux_X.XX.gz

, 

BHNloader_VXXX.gz

 and 

BHNjffs2_X.XX.gz.

 

These files contain all of the Blue Heat/Net Sync firmware. Follow the 

update

 command 

instructions for the 

SCM Command Reference 

to update each component.
