7.System Maintenance

7.1.System Upgrade

7.1.1. Storage Media and File Type

The storage media include:

„DRAM (Dynamic Random Access Memory): The program of the system control board runs in the DRAM.

„Flash (Flash Memory): It saves the software of the system control board and configuration files.

The system supports four types of files:

„System file: Includes the program files of all modules and the FPGA code of the ADU and VDU. The system file is a compressed file, and cannot implement system boot. For example, 04110468_DS41SMU_xducode_V02R00B10D04_20040915.bin.

„Program file of system control board: Used for the system control board to boot the system. It is usually hos_smu_vxxrxxbxxdxx.bin, for example, hos_smu_v02r00b09d06.bin.

„Configuration file: It is a text file that records user configuration information.

„LOG file: System log file.

 

For the V1.00 hardware, the VDU needs to upgrade (board

 

operating system). The download method is the same as

prompt

other methods.

7.1.2. Sequence of System Upgrade

System upgrade includes system file upgrade and upgrade of the program of system control boards without special sequence requirements. However, the version of the system file must be consistent with that of the program of the system control board. Otherwise, it may cause some abnormal symptoms.

7.1.3.Upgrading the System File

You can upgrade the system file in two modes:

„Upgrade the system file through the BOOTROM during equipment power-on

This mode is used under such circumstances: The equipment cannot be started normally because of a failure, so you cannot upgrade the system file through a command line; or software is loaded for the first time before the equipment is delivered (upgrade in the FTP/Xmodem mode).

„Upgrade the system file through a command line in compliance with the FTP/Xmodem protocol after the equipment is started
