9.1 Upgrade and Maintenance Overview
Devices can be upgraded and maintained by activating GTL license files, upgrading system
software, managing patches, monitoring CPU and memory usage, or restarting devices.
9.1.1 License Authorization
The AR2200 provides a management platform of license authorization. You can apply for,
upgrade, and activate license files to obtain corresponding rights.
If new devices are deployed, you can purchase new licenses as needed to enable license-
controlled features and functions on the devices. This reduces purchase costs. If the capacities
of the existing devices are expanded, you can update the licenses used on the devices to enable
more license-controlled features and functions.
To use the PBX function on the AR2200, apply for a license.
9.1.2 Software Upgrade
Software upgrade meets users' requirements for new functions by upgrading the patch file,
system software, configuration file, PAF file, and license file.
Software upgrade involves software downloading and software loading. Software downloading
includes:
l Remote downloading
l Local downloading
9.1.3 Patch Management
Loading a patch onto the system software allows the system software to be upgraded in service
without interrupting services on the device. This also improves Quality of Service (QoS).
During device operation, the system software may need to be modified due to system bugs or
new function requirements. The traditional way is to upgrade the system software after powering
off the device. This, however, interrupts services and affects QoS.
By means of patch management, the system software can be upgraded in service without
interrupting services.
Table 9-1 provides details on patch status.
