Functions and Features:
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 EH1D200CMU00installed, fans run at full speed.
Power Module Management:
The EH1D200CMU00 provides the following power module management functions.
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.
Indicators and Ports

Table 2 Indicators on the EH1D200CMU00 panel
| Number | Indicator | Color | Description |
| 1 | RUN/ALM: running status indicator | Green | Slow blinking: The card software is running properly. Fast blinking: The card software is unregistered. |
| Red | Steady on: The card has failed, and the fault requires manual intervention. Slow blinking: The switch is reporting an alarm. For example, a CMU, fan module, or power module on the switch fails. Fast blinking: The input power is insufficient or a 1600 W DC power module is installed. |
| 2 | ACT: active/standby status indicator | Green | Steady on: The card is the active CMU. Off: The card is the standby CMU. |
