The operating system (CentOS) software upgrade is performed using yum software package manager. The repositories sites providing RPM packages are configured from /etc/yum.repos.d/. TelcoBridges provides a modified CentOS repository copy (http://repo.telcobridges.com) of the official CentOS repository.

If the unit or Linux server does not have access to Internet (or does not have DNS configured), you should configure an offline CentOS repository on your local machine as explained in the section bellow.

Offline repository configuration

First, SSH to your unit do determine which version of the OS your system is using:

# cat /etc/redhat-release

CentOS release 5.11 (Final)

CentOS Linux release 7.2.1511 (Core)
