Fan module management
The EH1D200CMU00 provides the following fan module management functions:
Fan module presence detection
Fan module registration management
Fan speed monitoring
Fan speed control
Management and report of fan module alarms
Query of fan module electronic labels
The EH1D200CMU00 supports real-time fan module presence detection. Fan modules in the chassis register with the EH1D200CMU00. After they register, the EH1D200CMU00 obtains electronic labels of the fan modules and saves the electronic labels for users to query. Meanwhile, the EH1D200CMU00 monitors the speed and alarms of the fan modules in real time.
When detecting an alarm about a fan module, the EH1D200CMU00 reports the alarm to the MPU. When the alarm is cleared, the EH1D200CMU00 reports alarm clearance to the MPU.
When the EH1D200CMU00 receives a fan speed adjustment instruction from the MPU, it delivers the instruction to the fan modules. The fan modules then adjust their speed according to the instruction. If a chassis has no EH1D200CMU00 installed, fans run at full speed.
The EH1D200CMU00 supports real-time power module presence detection. Power modules in a chassis register with the EH1D200CMU00. After they register, the EH1D200CMU00 obtains electronic labels of the power modules and saves the electronic labels for users to query. Then the power modules are managed using the RS485 bus or I2C bus:
Using the RS485 bus:
The EH1D200CMU00 queries the current and voltage of power modules in real-time.
When detecting an alarm about a power module, the EH1D200CMU00 sends the alarm to the MPU. When the alarm is cleared, the EH1D200CMU00 reports alarm clearance to the MPU.
When the switch is working in deep energy saving mode, the EH1D200CMU00 automatically shuts down redundant power modules to save power. You can set the deep energy saving mode using the set power manage mode command.
Using the I2C bus:
When detecting an alarm about a power module, the EH1D200CMU00 sends the alarm to the MPU. When the alarm is cleared, the EH1D200CMU00 reports alarm clearance to the MPU.
