EH1D200CMU00 Hardware Description

 

Introduction

The EH1D200CMU00 can be installed in:

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

 

Power module management
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.
