firmware like U-Boot, Linux Kernel, and FPGA must be sent by the factory to
execute updating process.
1.6.9 Power Supply Subsystem
MUXpro can be ordered with100 to 240 +10VAC, 50/60+3 Hz or -36 to -72 VDC
power supply. The unit does not provide a power ON/OFF switch; therefore, starts
operating as soon as power is connected.
1.6.10 Supervision, Diagnostics and Performance Monitoring
The MUXpro supports comprehensive diagnostics, performance monitoring, and
supervision and maintenance capabilities, for easy maintenance and rapid
detection and location of faults.
1.6.10.1 Alarm Reporting
MUXpro generates time-stamped alarm messages that cover all the system
events. The time stamp is provided by an internal real-time clock. Up to 255 of the
most recent alarms can be stored in an internal buffer; in case the MUXpro is
powered down, up to 100 of the most recent alarms are stored in non-volatile
memory, and remain available for display and analysis after the MUXpro is
powered up again.
The alarm messages stored in the buffer can be read on-line by means of the local
supervisory terminal, a Telnet host or Web browser, and can also be automatically
sent as traps to selected management stations.
Note:
Before you upgrade RAMdisk, you are suggested to copy
your VCDB parameters in advance. Otherwise all the
setting will be returned to factory default because after
upgrading RAMdisk, the system will restart to confirm its
version. VCDB parameters make a lot of difference and
lead system cannot save previous parameter setting.
