ZXR10 5900 5200 Product Description
The functions of the system control module are:
 Starts the processes in the specified order
 Maintains the chassis diagram, which collects and updates running status
information of the switch chassis during its operation, including port status etc.,
and takes appropriate actions when the port is Up/Down
Starts scheduling fixed timer after receiving notification from system process

management module. After the system control process receives notification
from the scheduled timer it displays the result on the user interface, and stops
timer scheduling when the synchronization in finished, and displays welcome
information.
Starts multiple timers of different periods to perform the following functions:
Process monitoring: The system control process starts timer to monitor the

status of all the processes at regular intervals. When any process is suspended,
the system will print prompt message in Debug version, while the system will
reset the board in Release version.
 Clearing the Watchdog: The Watchdog is added to avoid the faults that may
occur during the running of the board. The software can set the WDG_TIME. If
the watchdog is not cleared in this period, the watchdog will reset the
equipment. The watchdog is cleared by the system control process. If the
system control process fails to clear the watchdog within WDG_TIME due to
reasons such as suspension, the equipment will be reset.
System running indicator/panel indicator control: The system running

indicator indicates the current running status of the system, and the panel
indicator indicates the running status of the boards. The system control
process invokes the panel indicator driver function provided by the BSP to
periodically turn on and off the running indicator and other alarm control and
port status indicators.
Providing statistics: It is to provide statistics of the resources and the running

status of the processes in the system. The statistics covers the size of the
memory, memory utilization, CPU utilization, system running time, and the
processes encapsulated by the ROS. The parameters about the processes
include stack size, scheduling times, CPU occupation time, seizure times, and
the information about the process synchronous/asynchronous message
queues.
Software Upgrade

First, the upgrade software is obtained from a specified FTP server from the network and
then stored in the FLASH. The local file system is a DOS-type file system. After the
software has been verified as valid, the compressed software file is decompressed, and
then stored in the RADDISK. Version upgrade is simple, thus remote version upgrade
can be done easily.
