Introduction to the Dorado management module

Dorado disk modules are described as follows: Disk modules provide storage capacity for service data and function as system coffers.

Dorado power modules are described as follows: The storage system supports AC power modules. Power modules can ensure that the controller enclosure works correctly in maximum power consumption mode.

Indicators on a Dorado power module are described as follows: Power module running/alarm indicator Steady green: The power supply is correct. Blinking green: The power input is normal but the device is powered off. Steady red: The power supply is faulty. Off: No external power is input. BBU running/alarm indicator Steady green: The BBU is fully charged. Blinking green (1 Hz): The BBU is being charged. Blinking green (4 Hz): The BBU is being discharged. Steady red: The BBU is faulty.

Dorado expansion modules are described as follows: Each expansion module provides one PRI expansion port and one EXP expansion port. An expansion module is connected to controller or disk enclosures through expansion ports to support communication and data transmission between controller and disk enclosures.

Indicators on a Dorado management module are described as follows: Power indicator on a management module Steady green: The interface module is working correctly. Blinking green: The interface module receives a hot swap request. Steady red: The interface module is faulty. Off: The interface module is powered off or is hot-swappable. Management network port speed indicator Steady orange: Data is being transferred at the highest rate. Off: The data transfer speed is lower than the highest speed. Link/Active indicator of the management network port Steady green: The port module is properly connected. Blinking green: Data is being transferred. Off: The port is incorrectly connected.
