Introduction
The EH1D200CMU00 can be installed in:
- Slots CMU1 and CMU2 in an S12700E-4 chassis.
- Slots CMU1 and CMU2 in an S12700E-8 chassis.
- Slots CMU1 and CMU2 in an S12700E-12 chassis.
Functions
The EH1D200CMU00 consists of the following modules:
- Device management module: sends interface control signals for device management.
- Backplane interface module: provides management channels for power modules, fan modules, and communication channels between the active and standby EH1D200CMU00 cards.
The EH1D200CMU00 manages power modules and fan modules in a chassis. The EH1D200CMU00 is hot swappable. Two EH1D200CMU00 cards can be installed in a chassis to work in active/standby mode.
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.
Power module management
- Power module presence detection
- Power module shutdown
- Power module registration management
- Voltage and current monitoring
- Management and report of power module alarms
- Query of power module electronic labels
The EH1D200CMU00 supports real-time power module presence detection. Power modules in the 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. Meanwhile, the EH1D200CMU00 queries the current and voltage of power modules in real time.
When detecting an alarm about a power module, the EH1D200CMU00 reports 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.
